Obsevations were taken on percent infestation of shoot and fruit on day before, 7DAS and 14DAS after two sprays Results revealed that highest yield is recorded in Spinosad 45 SC (101.4 q/ha), followed by nisco sixer plus (82.2 q/ha), Imidacloprid 17.8 SL (72.5 q/ha). Insecticidal treatment with Spinosad 45 SC with 1:5.66 had the highest cost benefit ratio, followed by Nisco sixer plus (1:4.99).

Insecticide Usage Pattern and Knowledge Level of Farmers on Insecticides Handling to Manage Leucinodes orbonalis Guenee in Brinjal Across Different Localities

A detailed survey was carried out to record the insecticide usage pattern in brinjal and knowledge level of farmers on insecticides handling to control brinjal shoot and fruit borer, Leucinodes orbonalis from brinjal growing farmers of Shivamogga (Karnataka), Coimbatore (Tamil Nadu), Tirupati and Vijayawada (Andhra Pradesh), Pune (Maharashtra) and Gadwal (Telangana) Districts of India during 2020-21. The information on insecticide usage pattern was gathered from twenty progressive farmers from each selected location using well-structured questionnaire. The data revealed that farmers used eighteen different insecticides to manage L. orbonalis in brinjal. Among the different insecticides the highest usage of chlorantraniliprole 18.5 SC (70%) was reported followed by emamectin benzoate (55%) and lambda-cyhalothrin (33.33%). The number of application of insecticides in the six locations varied from 10.8 to 22.20 per cropping season at an interval ranging from 7.0 to 12.4 days. In order to get information on insecticide recommendation, 48.33 per cent of brinjal farmers approached pesticide dealer shops and 78.33 per cent farmers did not pay attention towards label information given in pesticide containers. In different localities, around 51.67 per cent of farmers sprayed insecticides at recommended dose and nearly 71.67 per cent of farmers did not follow any safety measures while undertaking spraying operation. In all the locations (83.33%) farmers relied only on Insecticides and only around 10.0 per cent famers followed cultural control methods for L. orbonalis control.

IDENTIFIKASI SERANGGA (INSEKTA) YANG MERUGIKAN PADA TANAMAN CABAI RAWIT DI DESA SISARAHILI EKHOLO KECAMATAN LOLOWAU KABUPATEN NIAS SEALATAN

Agriculture is an activity of utilizing biological resources by humans to produce food, industrial raw materials with the aim of fulfilling their needs. Chili (Capsicum annuum L.) is a horticultural commodity that has important economic value in Indonesia, so chili cultivation is very attractive to farmers. This study aims to determine the types of insects that are detrimental to chili plants. This type of research is descriptive qualitative research. This research was conducted from 16 December to 12 January 2023. This research was also carried out in the village of Sisarahili Ekholo, Lolowa'u District, Nias Selatan Regency. Identification is one of the ways or actions taken to find out the description of something being studied as a determinant or determination of identity, one example is insects (Insecta). Insects as a component of biodiversity have an important role in agricultural ecosystems, namely as herbivores, parasitoids, predators and environmental bioindicators. Based on the results of the research and discussion, it was found that the research obtained several types of insects, namely green grasshoppers (Atractomorpha), stinging bugs, stem and shoot borer insects (Scirpophaga innotata), green ladybugs (Hemiptera), and caterpillars. Suggestions from researchers are that people should be able to use appropriate techniques in exterminating insects on rice plants, because not all types of insects found on rice plants are harmful but some are beneficial such as: bees, butterflies and dragonflies and several other types of insects .

The Effect of Combining Repellent Intercrops on the Host-Finding, Ovipositional Preference, and Damage Potential of Eggplant Fruit and Shoot Borer, Leucinodes orbonalis Guen´ee

The eggplant fruit and shoot borer (Leucinodes orbonalis Guen´ee), also known as EFSB, is anotorious major insect pest of eggplants. Researchers have been striving to find effective management strategies to reduce the population of this pest and achieve higher yields with minimal or no insecticide application. This study aimed to investigate the influence of intercropping eggplants with different repellent plants as a means to mitigate EFSB infestation, considering the heavy reliance on insecticides in eggplant production. The experiment followed a Complete Randomized Design (CRD) with six treatments replicated three times.The treatments included lemongrass, oregano, marigold, a combination of repellent plants (lemongrass + oregano + marigold), farmers’ practice (methomyl), and the control (sole eggplant). Data analysis was conducted using analysis of variance, and the differences across treatment means were calculated using Tukey’s Honest Significant Difference. The results revealed that intercropping eggplants with marigold, oregano, and lemongrass exhibited repellent effects on EFSB moths, leading to a significant reduction in the percentage of shoot damage. These findings suggest the potential utilization of intercropping with repellent plants as a more environmentally friendly approach, reducing the need for insecticide usage and potentially increasing farmers’ income.

Efficacy of Native, Commercial <i>Bacillus thuringiensis</i> and Fungal Formulations Against Okra Shoot and Fruit Borer

Okra shoot and fruit borer commonly known as spotted bollworm is a major pest of the economically important crops, viz., cotton and okra. Field experiment was conducted with 13 treatments including seven native Bt isolate treatments viz., 49, 51, 52, 55, 16, HD1 and 493 along with commercial Bt treatment (Dipel), three Entomopathogenic fungal treatments viz., Metarhizium anisopliae, Beauveria bassiana, Metarhizium rileyi, one chemical check viz., chlorantraniliprole and untreated control. The cumulative efficacy of treatments tested for the management E. vitella on okra during kharif 2021-2022 revealed that all the treatments were found effective over untreated control (20.08%). Among the treatments, Chlorantraniliprole 18.5% SC @ 0.27 ml l-1 was found superior with lowest mean fruit infestation (8.05%) and it was on par with M. rileyi (1x108 CFU g-1) @ 5 g l-1 (9.70%), isolate 493 (1x1010 CFU g-1) @ 3 g l-1 (9.17%), M. anisopliae (1x108 CFU g-1) @ 5 g l-1 (9.90%) and isolate 16 (1x1010 CFU g-1) @ 3 g l-1 (9.87%).

Evaluation of IPM Against Pest Complex of Okra

With the major pests such as shoot and fruit borer, Earias vittella (Lepidoptera: Noctuoidea), whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae) are causing qualitative and quantitative loss to okra. In this study along with this two other important pests like leafhopper, Amrasca bigutulla bigutulla and aphids, Aphis gossypii were also studied. For controlling pests sustainable approach is required which causes less environmental hazard and economically affordable to farmers. The Integrated Pest Management (IPM) module based upon integration of resistant cultivars, cultural, mechanical and physical methods, natural enemies, biopesticides and pesticides to suppress pest population is the best solution.

Bio-efficacy of Solvent Extracts of Botanicals against Brinjal Shoot and Fruit Borer, Leucinodes orbonalis (Guenee) under in vitro Condition

This study evaluated the effectiveness of solvent extracts of A. indica, C. inerme, and O. sanctum against Leucinodes orbonalis, a borer of brinjal shoots and fruit. The room temperature solvent extraction method was used to get the acetone, petroleum ether, and methanol extracts of the botanicals, A. indica 100% (76.54%) methanol extract had the highest antifeedant efficacy. The acetone and petroleum ether extracts of A. indica 100% (65.45%; 60.42%) and C. inerme 100% (57.25%; 51.78%) were also effective antifeedants. The per cent larval mortality of L. orbonalis was highest in the methanol, acetone and petroleum ether extracts of A. indica 100% (89.33%; 80%; 71.33%), A. indica 75% (76.67%; 70%; 67%) and A. indica 50% (68.67%; 63.67%;58.67%), respectively.

Comparative efficacy of some botanical insecticides in the control of eggplant fruit and shoot borer (leucinodes orbonalis guenee)

An Experiment was conducted from December, 2021 to April, 2022 in an open field of the Teaching and Research Farm of Akwa Ibom State University, Obio Akpa Campused to evaluate the efficacy of botanical insecticides in the control of eggplant (Solanum melongena L.) fruit and shoot borer (EFSB) Leucinodes orbonalis Guenne), Four week-old eggplant seedlings (ARJANI FI) were transplanted to bags filled with 30kg top soil, each. There were nine insecticide treatments (T0 = Control (No insecticide), T1 = Scent leaf extract (SLE 10% w/v), T2 = Pawpaw leaf extract (PLE 10% w/v), T3 = Neem leaf extract (NLE 5% w/v), T4 = Neem oil (N.O 3% v/v), T5 = Neem oil (N.O 5% v/v), T6 = Garlic bulb extract (GBE 3% v/v), T7 = Emamectin Benzoate (EB 1.33g/L) and T8 = Neemsol (0.2% v/v). Plants were sprayed three times: four weeks after transplanting (4WAT), 6WAT and 8WAT. The experiment was laid out in a completely randomized design. Data obtained were subjected to analysis of variance and means compared at 5% probability level using Student-Newman-Keuls Test. The results obtained showed that the insecticide treated plants significantly (P< 0.05) had lower percentage of fruit and shoot infestation by EFSB relative to the untreated plants. The unsprayed plant significantly (P< 0.05) had the highest percentage of Fruit infestation by both number and weight basis. Fruits from the untreated plants had significantly (P< 0.05) more number of bored holes and larvae than the insecticide treated plants. Among the insecticide treatments, EB and N.O 5% had plants with significantly lower shoot infestation (10.42 and 12.50%), fruit infestation by weight (17.07 and 25.60%), number of larvae/fruit (0.33 and 1.00), respectively. The botanicals tested in this work could be incorporated into integrated pest management programme of eggplant fruit and shoot borer. Therefore, Emamectin Benzoate was observed to be the best and hence recommended treatment based on parameters measured.

The Apanteles adelinamoralesae species group (Hymenoptera, Braconidae) from Brazil, with descriptions of three new species reared from fruit borers(Lepidoptera, Depressariidae).

With more than 633 species, Apanteles is the largest genus within the subfamily Microgastrinae (Hymenoptera, Braconidae). We describe three new species reared from pests of commercial fruits, Apanteles ahuacatl Shimbori, Giacomelli & Fernández-Triana sp. n., A. aratiku Shimbori sp. n., and A. mayochinchipe Shimbori sp. n. They parasitize caterpillars in the subfamily Stenomatinae (Depressariidae): the soursop moth Cerconota anonella (Sepp), in fruits of sweetsop (Annona squamosa L.) and atemoya (Annona squamosa x Annona cherimola Mill.) (Annonaceae), the avocado borer Stenoma catenifer Walsingham, in fruits of avocado (Persea americana Mill.) (Lauraceae), and the cacao shoot borer Stenoma decora Zeller, in fruits and shoots of cacao (Theobroma cacao L.) (Malvaceae). The new Apanteles species are included in an expanded version of the key provided by Fernández-Triana et al. (2014) for the Apanteles adelinamoralesae species group. In addition, the previous record of Apanteles stenomae Muesebeck in Brazil is revised and considered to actually represent the species A. yolandarojasae Fernández-Triana.

A SIMPLE MASS REARING METHOD FOR BRINJAL SHOOT AND FRUIT BORER <i>LEUCINODES ORBONALIS</i> GUENEE

A simple, effective and economically cheaper method for mass rearing of the brinjal shoot and fruit borer, Leucinodes orbonalis Guenee was developed using both modified artificial diet fortified with brinjal powder and natural diet - potato. A comparison of the various biological parameters such as egg incubation period, larval period, larval weight (12-day old), pre-pupal period, pupal period, pupal weight (1-day old), adult longevity, fecundity, oviposition period and sex ratio of different life stages of the test-insect were studied for both the food sources in this investigation. The larval and pupal periods on natural (potato) diet were 14.58± 1.51 and 6.7± 1.22 days respectively, with a mean fecundity of 165.55± 36.26 per female and a mean life cycle of 26.91days. The larval and pupal period of shoot and fruit borer reared on modified diet were 15.97± 1.24 and 6.25± 1.23 days respectively with a mean fecundity of 149.45± 25.83 per female and a mean life cycle of 25.26 days. Provision of a suitable site for adult mating and oviposition was attained by designing a separate mating chamber along with a suitable egg laying substratum. Thus, an easy and economical rearing technique could successfully support the rearing to six generations of target-insect in laboratory.

Seasonal Incidence of Insect-pests, Natural Enemies and Pollinators of Solanum melongena L. and Correlation between Their Daily Occurrences with Weather Parameters

The investigation was carried out at K.V.K Instructional Farm of Bhawanipatna, Kalahandi, Odisha, India during the cropping season 2020-21. Brinjal shoot and fruit borer (BSFB), whitefly, and jassid were the most significant pests found in brinjal, Solanum melongena L. while epilachna beetle was of minor importance as it was found in much lower numbers and caused less damage. They were found from 2nd to 16th Standard Meteorological Week (SMW). The population of whitefly had significant negative correlation with morning, evening and mean Relative Humidity (RH). There was a significant negative correlation of population of jassids with evening and mean RH but significant positive correlation with bright sunshine hours. The population of epilachna had significant negative correlation with morning, evening and mean RH but positive correlation with maximum, minimum and mean temperature. BSFB infestation on fruit had significant negative correlation with morning, evening and mean RH but positive correlation with maximum and mean temperature. There was a significant positive correlation of BSFB infestation on shoot with maximum, minimum and mean temperature but significant negative correlation with rainfall. The natural enemies found in brinjal ecosystem from 4th to 16th SMW and belonged to ladybird beetles, spiders, preying mantids, black ant, carabid beetle, syrphid flies, damselfly and chrysopids. The population of spiders had significant negative correlation with evening and mean RH but positive correlation with bright sunshine hours. There was a significant negative correlation of population of coccinellids with evening RH. The pollinators recorded from experimental field were honeybee and carpenter bee from 3rd to 16th SMW. Among them, carpenter bee, Xylocopa sp. was the most dominant visitor of brinjal flower in the field and was identified as potentially important in brinjal. The pollinators appeared in higher numbers during the blooming period and was the dominant species found in the field. The population of honey bees had significant negative correlation with evening RH.

Chemical ecology of Himalayan eggplant variety's antixenosis: identification of geraniol as an oviposition deterrent against the eggplant shoot and fruit borer.

Eggplant (Solanum melongena) suffers severe losses due to a multi-insecticide-resistant lepidopteran pest, shoot and fruit borer (SFB, Leucinodes orbonalis). Heavy and combinatorial application of pesticides for SFB control renders eggplant risky for human consumption. We observed that gravid SFB females do not oviposit on Himalayan eggplant variety RC-RL-22 (RL22). We hypothesized that RL22 contained an antixenosis factor. Females' behavior indicated that the RL22 cue they perceived was olfactory. To identify it, leaf volatile blends of seven eggplant varieties were profiled using solid phase microextraction and gas chromatography mass spectrometry. Seven RL22-specific compounds were detected in the plant headspace. In choice assays, oviposition deterrence efficacies of these candidate compounds were independently tested by their foliar application on SFB-susceptible varieties. Complementation of geraniol, which was exclusively found in RL22, reduced oviposition (> 90%). To validate geraniol's role in RL22's SFB-deterrence, we characterized RL22's geraniol synthase and silenced its gene in planta, using virus-induced gene silencing. Geraniol biosynthesis suppression rendered RL22 SFB-susceptible; foliar geraniol application on the geraniol synthase-silenced plants restored oviposition deterrence. We infer that geraniol is RL22's SFB oviposition deterrent. The use of natural compounds like geraniol, which influence the chemical ecology of oviposition, can reduce the load of hazardous synthetic larvicides.

Influence of Weather Factors on Incidence and Infestation of Shoot and Fruit Borer in Brinjal

Aims: To correlate the influence of weather variables on population dynamics, incidence and infestation of Brinjal shoot and fruit Borer (BFSB) in Brinjal.
 Place and Duration of Study: The study was carried out at Regional Research and Technology Transfer Station (RRTTS) at Ranital, Bhadrak Odisha and at Instructional Farm at OUAT, Bhubaneswar, Odisha for period of 1 year.
 Methodology: The population of Brinjal shoot and fruit Borer were recorded from transplanting to harvest of the crop. Five random plants were selected and tagged for observation recording, except boarder plants. To determine the percentage of affected shoots, brinjal plants showing signs of delicate shoots drooping, withering, and drying were counted. Similarly, the population was correlated with weather conditions and the number of fruits showing signs of bore holes on fruits was tallied to estimate the percent fruit infection.
 Results: The investigation indicates that quantitatively establish the relationship of weather parameters as varied with the dates of sowing (23 May,20 November2021, 21 January2022) and Brinjal fruit and shoot borer (BFSB).The studies revealed that the peak population of brinjal shoot and fruit borer was observed during 34th SMW (22-28 August), 5th SMW(30 January- 5 February) and 18th SMW(1-7May) with shoot infestation(38.44%), (11.10%) and (57.99%) respectively. The fruit was infested with a peak of 47.55%, 27.07% and 63.84% on 39th SMW (26 September- 2 October), 9th SMW (27February-5March) and 18th SMW (1-8May) respectively. The BSFB shows positive significant correlation with relative humidity.
 Conclusion: The population of BSFB fluctuates with change in temperature, rainfall, and relative humidity. On first sowing date BSFB population has a less population dynamics comparatively to other two sowing dates. So it is concluded for early sowing results in less pest population.

Farmers Perceptions on the Use of Insecticides For Management of Brinjal Shoot and Fruit Borer

The survey was conducted in Chattogram, Jashore and Mymensingh regions of Bangladesh to find out the farmers’ knowledge and perceptions about insecticide usages in brinjal for management of brinjal shoot and fruit borer (BSFB) during August 2014 to April 2015. All the farmers of three different study areas reported that BSFB is a major problem and needs to be controlled. On an average, 91.68% farmers used conventional chemical method as main protection technique by using only insecticide whereas only 5.54% farmers used IPM method and 2.78% used different types of cultural pest management techniques for controlling BSFB. On an average, 40.80% farmers used insecticide as single form and 59.20% farmers used it in the form of cocktail. During three and half months crop season 36.35 to 57.33 times spray can occur depending on the regions. On an average, 73.23% farmers followed the advice of pesticide dealers in selecting pesticides and their doses for spraying against BSFB. Only 7.69% farmers followed the advice of extension workers which is much less as compared to the pesticide dealers. On an average, 73.98% farmers reported that insecticide was applied without any protection measures.

Different Silicon Application Sources and Factors Influencing Mandibular Wear in Sugarcane Early Shoot Borer, Chilo infuscatellus Walker

Silicon (Si) can improve plant resistance to herbivorous insect attack. Early shoot borer (ESB), is one of the most solemn lepidopterans borers on sugarcane in India. Even with insecticide application, management of this pest is difficult. The management requires a fresh new approach. As a result, the current study aims to determine the effect of silicon on the early shoot borer, Chilo infuscatellus Walker, through biophysical factor analysis and mandibular wear documentation. When sugarcane leaves were treated with calcium silicate at 1000 kg/ha, scanning electron microscopy revealed the presence of silicified cells and trichomes, as well as increased cell wall thickness, silicon content, and waxes content. Furthermore, larvae of an early shoot borer fed silica-treated plants showed a complete wearing of mandibles as compared to untreated check.

Farmers perception on pest management practices and profitability analysis for five winter vegetable production

The purpose of the study was to determine the farmers' perceptions of management measures against insect and disease pests and the profitability of five winter vegetables grown in Bangladesh's Sirajganj area. The highest incidences of fungal infections, including curd rot of cauliflower and early blight of tomato, were discovered. One of the most destructive diseases of brinjal and tomato was wilt, which was caused by both fungi and bacteria. Farmers took the necessary steps to control aphids (40-150 insects m–2 or 20-50 infected shoots m–2), brinjal shoot and fruit borer (10-50 insects 10m–2 or 20-60 infected shoots or fruits 10m–2), and other insects at the threshold level. They employed physical, chemical, and Integrated Pest Management (IPM) techniques to manage the disease and insect pests. The greatest amount of insecticide spraying (35-45 times) was performed to control brinjal shoot and fruit borer insects. The entire manufacturing cost followed the pattern tomato > brinjal > bean > cauliflower > bottle gourd. The cultivation of brinjal yielded the highest return, gross margin, and net return (Tk. 987,000.00, Tk. 800,572.00, and Tk. 763,117.00 ha–1, respectively; US$ 1 = Bangladesh currency Tk. In contrast, bottle gourd farming yielded the lowest return (Tk 700,000.00 ha–1), and tomato cultivation yielded the lowest gross margin and net return (Tk 539,152.00 and 507,325.00, respectively). The brinjal cultivation had the highest profitability index, benefit-cost ratio (both variable and total cost basis), and rate of return on investment, whereas tomato cultivation had the lowest. Rot, blight disease, shoot and fruit borer, or fruit borer, and aphid were the most common pests of winter vegetables in the region surveyed. Finally, we discovered that brinjal is the most profitable vegetable in our area of study.
