The role of Hymenoptera parasitoids as mortality factors of Silba adipata McAlpine on cayenne pepper plants: parasitism and distribution patterns

Silba adipata (Diptera: Loncaeidae) is a new species that attacks white cayenne pepper in Bali. The research aimed to explore the role of these three types of parasitoids. New variables that have never been used before include spatial and altitudinal distribution patterns, the relationship between the level of parasitism and the level of population density of A. adipata according to plant phenology, and the level of parasitization of parasitoids on hosts at various altitudes in Bali, Indonesia. This research was carried out from April to July 2021 using a survey method in which samples were taken purposively from sample plants. The three parasitoids were distributed in all districts, except F. arisanus and A. japonica which were not found in Denpasar and Jembrana. Three parasitoid species play a role in controlling S. adipata in Bali Indonesia, namely A. japonica, F. arisanus, and D. longicaudata. Among the three parasitoids, A. japonica was most dominant at altitudes >750-1000 MASL, while F. arisanus at altitudes >500 - >1000 MASL and D. longicaudata at altitudes >250-500 MASL. The population densities of the three parasitoids were densely associated with S. adipata populations. The parasitoid that most effectively controls S. adipata in the field is F. arisanus.

ОБ ЭФФЕКТИВНОСТИ ПРИРОДНОЙ ПОПУЛЯЦИИ ПАРАЗИТОИДА ГРОЗДЕВОЙ ЛИСТОВЕРТКИ BASSUS TUMIDULUS (NEES, 1812) (HYM.: BRACONIDAE) НА ТАМАНСКОМ ПОЛУОСТРОВЕ

The paper presents the results of studies of trophic relationships of Lobesia botrana Den. et Schiff. (Lepidoptera, Torticidae) in the «parasitoid - insect-host» system in ampelocenoses. For the first time for the Anapa-Taman viticulture zone of the Krasnodar region, the species Bassus tumidulus (Nees, 1812) (Microdus tumidulus (Nees von Esenbeck, 1812), Therophilus tumidulus (Nees von Esenbeck, 1812) was established as a mass natural enemy of the European grape moth in the conditions of industrial plantings of grapes. During the observation period (2021-2023), this type of parasitoid was the most common in terms of the number of infected specimens of L. botrana, its frequency of occurrence exceeded that of other parasitoids recorded in these studies by 2.7 times. There is a lack of knowledge of the parasitoid fauna in the consortia formed around the European grape moth in ampelocenoses. Knowledge of trophic relationships of the main economically significant pest of the vineyards of the Anapa-Taman zone of the Krasnodar region as a mechanism for regulating its abundance can help in the development of effective biologized protection measures in the fight against it. According to the results of extirpation, the seasonal dynamics of the flight of the adult parasitoid was revealed and compared with the life cycle of the harmful lepidopteran host. A complete adaptation of Bassus tumidulus to the target phases of the development of the European grape moth has been established. The conclusion is made about the specialization of the polyphage to this pest in the region. The characteristic features of Bassus tumidulus population dynamics were revealed, namely, an increase in the density of the hymenoptera population in ampelocenosis by the end of the growing season. The data of the biology of Bassus tumidulus, given in the literature, have been confirmed.

The effect of integrated pest management on Scirpophaga innotata population and natural enemies on rice field in South Sulawesi, Indonesia

Abstract. Rahmawasiah, Abadi AL, Mudjiono G, Rizali A. 2022. The effect of integrated pest management on Scirpophaga innotata population and natural enemies on rice field in South Sulawesi, Indonesia. Biodiversitas 23: 4510-4516. White rice stem borer, Scirpophaga innotata, is an important pest on rice plants that needs attention because the population is quite large in Luwu Raya. This pest attacks rice plants at all growth stages and can result in yield losses in rice production. Synthetic insecticides are a common control technique used by farmers to control these pests. The continuous use of pesticides will certainly have a negative impact. Therefore, pursuing effective control strategies and maintaining environmental sustainability is necessary. This study aimed to determine the white rice stem borer population and its natural enemies on rainfed land, and permanent irrigated lands managed conventionally and integrated pest management. The research was carried out using insect sampling techniques and calculating the white rice stem borer population and natural enemies in rice cultivation. In rainfed and irrigated rice fields, rice cultivation was carried out using conventional methods and integrated pest management (in the form of planting refugia and regulating the use of synthetic pesticides). The sampling was carried out on plants from the vegetative phase to the generative phase. The type of insect taken was the white rice stem borer in the form of collecting groups of eggs and larvae. Imago was observed visually and using a farmcop. In addition, the collection of natural enemy insects on the plantation was also carried out. The results showed that the application of the integrated pest management system caused no significant effect on the decline of the white rice stem borer population in both rainfed and permanently irrigated lands in Luwu Raya. The white rice stem borer population was more commonly found in rainfed land than permanently irrigated land. The parasitoids found were Telenomus rowani, Tetrastichus schoenobii and Trichogramma japonicum. The population of Telenomus rowani was more numerous than other types of parasitoids. On average, the parasitoid population was more in the land managed by integrated pest management (IPM) application than the conventionally managed land. The predators found on the land were Oxyopes javanus, Agriocnemis femina, Conocephalus longipennis, Menochilus sexmaculata, Ophionea nigrofasciata, Micraspis lineata, and Paederus fuscipes. Predator populations were more on land managed with the application of IPM than on land managed conventionally.

Native Parasitoids of Fall Army Worm Spodoptera frugiperda (J E Smith) in Maize

Fall Army worm Spodoptera frugiperda (J E Smith) is a devastating, polyphagous pest which entered India during 2018, starting from Karnataka and spreading to other states. This study on its native parasitoids and their parasitisation efficiency in maize crop under Punjab conditions. The S. frugiperda larvae were collected during kharif 2019 and 2020, and it was found that no parasitoids could be observed in 2019, as the pest recently invaded the crop in late season. But, during kharif 2020, two types of parasitoids were observed - Campoletis sp. (Hymenoptera: Ichneumonidae) and Chelonus formosanus Sonan (Hymenoptera: Braconidae); these which existed as natural enemies of Chilo partellus were found to adapt effectively with the new invasive pest. The parasitism rate of 21.92 and 16.33% was observed for the Campoletis sp. and Chelonus formosanus, respectively.

Types and Percentations of Parasitization Egg Parasitoids Spodoptera frugiperda J, E. Smith in North Sulawesi

Corn (Zea mays L) is the main commodity of agricultural crops in Indonesia. There are two groups of corn that are cultivated, namely ordinary corn (food corn) and sweet corn. Food corn is mainly used as a raw material for making food, which is used as a raw material for making animal feed raw materials and other industrial products. Easy cultivation, can grow in various conditions, stable selling prices and easy to market are the main driving force for high interest of the farming community to cultivate it. Spodoptera frugiperda larvae are polyphagous and attack many plant species. S. frugiperda larvae feed on more than 350 species of plants in 76 families. S. frugiperda is a typical migratory pest and this migratory behavior is an adjustment strategy to find a more profitable habitat. S. frugiperda is one of the most dangerous invasive pests due to its short life cycle. An adult female lays 900 – 1200 eggs in her life cycle. The purpose of the study was to inventory and analyze the egg parasitoid of S. frugiperda and the percentage of parasitization The analysis of the types of egg parasitoids of S. frugiperda was carried out through an inventory and identification process, while the percentage of parasitization was carried out using a randomized block design consisting of 5 treatment groups of eggs from 5 regions and three replications. The results of the inventory and identification contained two types of parasitoids, namely: Telenomus sp. and Trichogramma sp. The highest percentage of total parasitization was from Manado City at 85% and the lowest was from Bolaang Mongondow at 5%. Telenomus sp. higher percentage of parasitization than Trichogramma sp. Parasitization percentage of Telenomus sp. on eggs of S. frugiperda the highest came from Manado by 63% and the lowest came from Tomohon by 3%, while the percentage of parasitization of Trichograma sp. The highest came from Manado at 22%, and the lowest came from Bolaang Mongondow Regency at zero percent. In conclusion, there are 2 types of egg parasitoids in S. frugiperda eggs, namely the parasitoid Telenomus sp and the parasitoid Trichogramma sp., the percentage of parasitization of Telenomus sp. on eggs of S. frugiperda the highest sample from Manado and the lowest sample from Tomohon. Percentage of parasitization of Trichograma sp. the highest sample of S. frugiperda eggs from Manado, and the lowest sample from Bolaang Mongondow.

Functional and Taxonomic Diversity of Stinging Wasps in Brazilian Atlantic Rainforest Areas.

Vespoidea are the most functionally diverse superfamily of Hymenoptera. Ecological studies involving this family are primarily based on eusocial groups, including ants and social paper wasps. In the present study, we examine stinging wasp (Vespoidea) faunal diversity in the Atlantic Rain Forest, which is one of the most diverse and threatened ecosystems in the World. Three conservation areas were sampled employing a standardized sample protocol. Families and functional groups of Vespoidea were collected in each area, with the exception ants (Formicidae), and analyzed using diversity analyses, to generate taxonomic diversity and distinctness indices. Results indicated Pompilidae was the most diverse family, and the idiobiont parasitoid type was the most diverse functional group in the three study areas. Núcleo Picinguaba of the Parque Estadual da Serra do Mar was taxonomically and functionally the most diverse and species rich area. Parque Estadual Intervales showed the highest number of dominant species and diversity of koinobiont parasitoids, while the Rebio Sooretama exhibited a decrease in several diversity parameters.

Movement of Introduced Biological Control Agents onto Nontarget Butterflies, Hypolimnas spp. (Lepidoptera: Nymphalidae)

Since 1911, over 100 species of exotic organisms have been deliberately introduced for biological control of various pests on Guam. Of these, 27 species were released against seven lepidopterous pests including one butterfly and one skipper. Recently, concern has mounted about the negative effects of these introduced biocontrol agents on nontarget species, particularly endemic island species. Guam may have suffered extinction of as much as 20–25% of its butterfly fauna. To determine the extent of movement and possible impacts of biocontrol agents on nontarget butterflies, mortality factors affecting juvenile stages of Hypolimnas anomala (Wallace) and Hypolimnas bolina (L.) were studied. Both species were attacked by the same parasitoids and predators, which included native, accidentally introduced, and deliberately introduced species. Parasitoids killed 2.4% of the eggs of H. anomala , and ants removed about 25% of the eggs. Parasitization was about 40% in H. bolina , and ants killed about 35% of the eggs. One species introduced for biological control, Trichogramma chilonis Ishii, was found parasitizing the eggs, but it caused little mortality. No larval parasites were reared for either species. H. anomala suffered heavy mortality from a disease. Both species were attacked by ants and two exotic, self-introduced predators. The major pupal parasite was Brachymeria lasus (Walker), a deliberate biological control introduction. B. lasus parasitized 24.6% of the pupae of H. bolina and 2.9% of those of H. anomala . Ants attacked 17% of H. anomala pupae and 7% of those of H. bolina. B. lasus and T. chilonis are polyphagous parasitoids that have the potential to affect a variety of nontarget species. This type of parasitoid, and highly polyphagous predators like ants, should require more intensive evaluation and review for use in classical biological control programs than more specialized species.
