Dissemination of phosphorescent microbial agents by honey bees (Apis mellifera L.) in apple orchards

Honey bees are commonly used for pollination in apple orchards. This study aimed to develop a bee-vectoring scheme whereby honey bees (Apis mellifera L.) deliver microbial agents (Bacillus amyloliquefaciens MBI600) against fire blight from a dispenser at the entrance of the beehive to apple flowers. The efficiency of disseminating phosphorescent microbial agents (PMA) by honey bees was compared across four apple orchards; (A) with installed insect nets, (B) isolated on an island, (C) adjacent to other apple orchards and apiaries, and (D) near C within 50 m and without beehives. The average detection ratio of PMA on bees visiting flowers was 100 % in orchard (A) and (B), whereas in (C) and (D) it was 54.5 % and 40.0 %, respectively. Detection of PMA on apple blossoms was also 100 % in (A) and (B), but significantly low in (C) and (D) at 52.8 % and 12.9 %. In orchards (A) and (B), PMA adhered to pistils at high ratios of 98.0 % and 96.3 %, while in orchard (C), it was significantly lower at 9.3 %. Phosphorescence intensity in flowers and the proportion of apple pollen loads collected from incoming bees were also investigated. Finally compared to the orchard (A) and (B), open orchard (C) and (D) showed significantly lower microbial agent spread efficiency by honey bee vectoring. For open orchards, supplemental strategy to enhance bee vectoring could include increasing the number of hives in the orchard and temporarily relocating neighbor’s beehives during flowering, or supplying additional dispensers to nearby apiaries.

Insect community structure in young and productive coffee farms under leucaena shade of Jember Regency, East Java, Indonesia

The developmental phase of Robusta coffee plantations with agroforestry systems exhibits varying ecosystem characteristics (biotic and abiotic), therebyinfluencing the dynamics of insect community composition within them. One of the major coffee-producing centers in East Java is Jember Regency, where coffeecultivation commonly employs agroforestry systems with various shade trees. Understanding the abundance of insect species in agroforestry coffee plantations is important for determining insect pest control measures. This research aims to study the insect community structure in young coffee and productive coffee farms. Insect sampling was conducted in young coffee farms and productive coffee farms at the Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute (ICCRI), by using road sampling methods with insect nets and pitfall traps. Both types of plantations utilize Leucaena sp. var L2 as shade trees, forming agroforestry coffee plantation systems. Data analysis was performed by calculating the Shannon-Wiener diversity index (H’) to assess insectdiversity and the independent sample t-test to determine differences in insect abundance based on functional roles between the two farms. The results indicatethat the composition and abundance of insects in productive coffee farms are higher than in young coffee farms, resulting in a higher insect diversity index valuefor productive coffee farms (categorized as high), while young coffee farms fall into the moderate category. Furthermore, based on their functional roles, productive coffee farms positively influence the abundance of herbivorous, predatory, parasitoid, and detritivorous insects.

Zoophilic flies (Diptera) of South Iran–the dominance structure and species composition

ABSTRACT Zoophilic flies play an important role in dairy farms by transmitting diseases to livestock. These flies can cause significant damage to animal husbandry through physical disturbance and the spread of pathogens. This study aims to identify insect species in both traditional and industrial animal husbandry settings, focusing on the dominant species of zoophilic flies. The research involved collecting livestock insects from March to October, between 2017 and 2021, using insect nets, sticky nets, and light traps. A total of 10,942 flies were collected from livestock farms in three counties Marvdasht, Shiraz, and Zarghan. The collected flies belong to 21 species from 6 families. Musca domestica, Fannia canicularis, Musca autumnalis, Stomoxys calcitrans, Muscina stabulans, Calliphora vomitoria, and Lucilia cuprina were identified as the dominant species. Musca domestica, F. canicularis and M. autumnalis accounted for 70.24% of the total number of flies on livestock farms. Among the collected samples, Eristalis tenax (Syrphidae) was found with a frequency of 0.96%. The importance of this species is related to the presence of its larvae that cause myiasis in livestock. Identification of the dominant species of flies put the scientific basis to reduce their populations in dairy farms and the costs caused by the damage made by these pests to livestock farms through safe ways, such as biological control.

Advanced methods for insect nets: red-colored nets contribute to sustainable agriculture

Development of advanced pest control methods that do not rely on insecticides is an important issue for sustainable agriculture. Particularly with regards to micro pests that are not only highly resistant to various insecticides but also because we are running out of options for which insecticide to use against them, resulting in enormous economic damage worldwide. Here we report that the effectiveness of the conventional insect net can be greatly advanced by changing their color to red that helps significantly reduce pesticide use. We demonstrate the red effect using Onion thrips, Thrips tabaci a main vector of Iris Yellow Spot Virus (IYSV) and Tomato Spotted Wilt Virus (TSWV) that cause serious damage to various vegetables. New red nets succeeded in suppressing the invasion rates and damages (white spots on the leaves) in a Welsh onion greenhouse with minimum use of pesticides. We discuss how red nets are compatible with labor-saving, sustainable agriculture and the future potential of “optical pest control” based on insect color vision and its behavioral response.

Keanekaragaman Coccinellidae Predator pada Ekosistem Pertanian Organik dan Anorganik di Provinsi Sumatera Barat

The main principle of pest control in organic farming is to reduce the use of synthetic chemicals, especially pesticides. On the other hand, pest control in agricultural systems prioritizes the conservation of natural enemies in these ecosystems. Coccinellidae predators are one of the potential natural enemies available in organic farming ecosystems. To optimize the potential of these natural enemies, it is necessary to study the diversity of these predators in organic farming. By knowing the species and abundance of Coccinellidae predators in organic farming ecosystems, a suitable conservation model can be designed for these natural enemies so that these predators can carry out their functions to control pests, especially aphids. This study aims to study the diversity of predatory Coccinellidae in organic and inorganic agriculture in West Sumatra Province. Coccinellidae predators are collected directly and use insect nets. The diversity of Coccinellidae predators was analyzed with the Shannon Winner and Simpson abundance indexes. Based on the exploration carried out on several organic farms in West Sumatra, 18 species of Coccinellidae Predators have been collected, and six species have not been identified. Next, it is proven that organic farming has a high diversity of 1.90 compared to inorganic farming, which is 1.65. The presence of predatory Coccinellidae in organic farming is more evenly distributed, namely 0.67. Menochilus sexmaculatus is one species that has the potential to be optimized as a biological control agent for aphids.

Exploration of The Species Richness of Butterfly (Hexapoda: Odonata) in The Rice Field Ecosystem of Perian village, Montong Gading, East Lombok

Several Odonata studies on Lombok Island still focus on forest and river habitat types. This causes the diversity of this insect group to be unknown in other habitats such as rice fields. This research aims to explore the richness of dragonfly species in the rice field ecosystem of Perian village, Montong Gading subdistrict, East Lombok district. Sample collection was carried out in May – June 2022. Dragonfly searches were carried out in the morning from 08.00 – 12.00, and in the afternoon from 14.00 – 18.00 on two transects determined purposively. The odonata found were documented using a digital camera, and captured using insect nets. Samples that were successfully collected were identified to the species taxon. The total odonata we found were 2 suborders, 5 families and 11 species. The suborder Zygoptera is the group with the highest species richness. For families, Libellulidae and Coenagrionida are the families with the highest species richness compared to other families. Of the 11 species that we found, 1 species is endemic, namely Euphaea lara lombokensis. Compared with the results of previous research conducted in Suranadi and Batu Bolong River, there are 5 species which are new records. The five species are Copera ciliata, Rhinocypha bisignata, Ischnura senegalensis, Ischnura heterosticta, and Brachythemis contaminata. The results of this study indicate that there are more species from the Odonata order on Lombok Island compared to previous reports.

Dragonfly Inventory and Active Time in Kasang Kulim Zoo Area, Riau, Indonesia

Dragonflies have an important role in ecosystem balance as biological control agents and environmental bioindicators because they are sensitive to changes in water quality. Community activities at the Kasang Kulim Zoo can cause changes to water quality. When habitat conditions change, Odonata (dragonfly) will also changes, both in distribution and diversity. This study aims to identify, invent and determine the activity time of dragonflies found in the Kasang Kulim Zoo area. Research was conducted at the end of March to mid-April 2023. Sampling used exploration method by using insect nets. The results obtained a total of 152 individuals belonging to 14 species, four families and two suborders (Anisoptera and Zygoptera). The family Libellulidae totaled eight species, Gomphidae one species, Coenagrionidae four species and Platycnemididae one species. The Libellulidae family are active from 08.00 am to 05.00 pm, while dragonfly species from the Gomphidae family and the Zygoptera suborder are active from 08.00 am to 03.00 pm. Dragonfly activity is influenced by air temperature, air humidity and sunlight intensity.

PENGGUNAAN HERBISIDA TRIKLOPIR UNTUK MENGENDALIKAN GULMA PADA PERKEBUNAN KELAPA SAWIT FASE BELUM MENGHASILKAN DAN PENGARUHNYA TERHADAP KEANEKARAGAMAN SERANGGA

Weed is one of the major problems in immature oil palm plantations. Weed control is carried out to optimize the growth of oil palm plants, and the method commonly used in the field is chemical control with herbicides. The active ingredient of the herbicide used in the field is triclopyr, however herbicide application is thought to affect the diversity of insects, especially those found in lower vegetation, at the same time it is necessary to observe the effect of herbicide application on insect diversity. This study aims to obtain an effective dose of herbicide to control weeds in immature oil palm plants and to determine the effect of herbicide application on insect diversity. This study used a Randomized Block Design (RBD) which consisted of 6 treatments and 4 replications. Triclopyr herbicide treatment doses were 864 g.ha-1, 768 g/ha, 672 g.ha-1, 576 g.ha-1, mechanical weeding and control. Insect sampling method uses insect nets and pitfall traps. The data obtained were analyzed using variance or F test at 5% level and further test was carried out by DMRT at 5% level. The results showed that the best dose of herbicide triclopir was 768 g/ha because it was effective in controlling the weeds of Borreria latifolia, Calopogonium mucunoides and Asystasia gangetica. Triclopyr herbicide application affects the diversity of insects and the even distribution of insects.

Advances in the Sustainable Use of Plastics in Horticulture—Perspectives, Innovations, Opportunities, and Limitations

The use of plastics in horticulture is reviewed with respect to its sustainability based on the traditional criteria of triple Rs (reduce, reuse, and recycling) plus a re-place strategy, taking into account possible alternatives. Hail (and insect) nets made of HD-PE, with their long-term use mostly on apple and polytunnels of LD-PE for cherry and strawberry as well as solarisation mulches (reuse), were found to be relatively sustainable solutions for their needs and are currently without alternatives. In contrast, standard black mulch, with its largest share among horticultural plastics, had the widest range of sustainable alternatives, ranging from biodegradable to spray mulch; few sustainable alternatives are available for fleeces and reflective mulches. For the third sustainable option, pilot recycling schemes were examined, such as PolieCoTM (Italy), MAPLATM (Spain), and ERDETM (Germany); they collect 30–50% of the agricultural plastics used in their respective areas, with a successful retrieval growth rate of ca. 20% per year in the case of ERDETM. For the fourth new R option (replace), future sustainability perspectives for the predominant black mulch are research into and development of better, biodegradable, non-fossilbased plastics, sprayable mulch; microbes for the digestion of deployed polyolefins and, for a certain limited range (on shade tolerant crops or in high-light intensity environment), hail nets and polytunnels that are equipped/substituted by/with solar panels (“agri pv”) for the concomitant sustainable production of green renewable energy.
