The brinjal fruit and shoot borer (BFSB), Leucinodes orbonalis Guenée (Lepidoptera: Crambidae), is a very detrimental pest that causes significant economic losses to brinjal crop worldwide. Infested brinjal fruits were collected from vegetable fields located at the ICAR-Indian Agricultural Research Institute (ICAR-IARI), New Delhi, India, during two consecutive seasons (2021-2022). The larvae of the pest were brought to the laboratory and reared under controlled conditions of 25 ± 0.5 °C and 70 ± 5% relative humidity, for the emergence of parasitoids...

Endoparasitoids are insects that develop within other insects, employing unique strategies to enhance their offspring's survival. They inject polydnavirus and/or venom into their hosts along with eggs, effectively suppressing the host's immune system. Polydnavirus from Braconidae and Ichneumonidae wasps can integrate into the host's genome to express viral genes using the host's transcription systems. However, the ability of parasitoids without polydnavirus to manipulate host gene expression remains unclear...

Two new species of Grotea Cresson are described from Brazil, Grotea claudiae Kumagai sp. n. and G. fernandoi Lima sp. n. New records and identification key for Brazilian species of Grotea are provided. Grotea amazonensis Herrera-Flrez, 2019 is proposed as nomen nudum.

Wandering spiders (genus Phoneutria) hold a prominent position as some of the worlds most medically significant venomous arachnids, especially in Brazil. In this study, we record and illustrate for the first time, the Darwin wasp Camera thoracica (Szpligeti, 1916) as a natural enemy of the ctenid Phoneutria nigriventer (Keyserling, 1891). Furthermore, we provide a description of the previously unknown male wasp, update and standardize the description of the female, and provide biological notes.

The parasitoid wasp genus Saltagenes Diller, 1995 is known only from the original description of a single species from Argentina. However, undescribed Saltagenes species occur throughout the Neotropical region and into the southern Nearctic. Here, I review the Saltagenes species of Costa Rica and describe seven new species: Saltagenes alboannulatus sp. nov., S. atrosomus sp. nov., S. escazuensis sp. nov., S. gauldi sp. nov., S. modicum sp. nov., S. pseudatrosomus sp. nov., and S. rotundiceps sp. nov. The generic diagnosis is revised to account for hitherto unknown morphological diversity of Saltagenes...

The Darwin wasp genus Chirotica Frster, 1869 (Hymenoptera: Ichneumonidae, Phygadeuontinae) is poorly represented in Brazilian entomological collections, with only three previously described species. Herein, four new species are described and illustrated: C. juquia sp. nov., C. maraca sp. nov., C. mariua sp. nov. and C. nigra sp. nov..

As a result of continuing research on the ichneumonid wasps of Costa Rica, two new species of Epirhyssa (Rhyssinae) are described: E. leonoreae and E. lewisi. A key is provided for the identification of all 14 species now known to occur in the country.

India is the world's largest cotton producer and the only country that grows all four cultivated cotton species. There have been very few studies on the diversity and abundance of natural enemies of cotton insect pests in these cultivated cotton species. Therefore, the current study (2016-2018) was conducted to assess the diversity and abundance of natural enemies that cultivated cotton species harbour. Phule Dhanwantari, Suraj, Suvin, RCH-2, and DCH-32 were the five genotypes used in the study, each with a distinct genetic background...

The carob moth, Ectomyelois ceratoniae (Zeller) (Lepidoptera: Pyralidae), is an important pest of pistachio causing direct damage to nuts during ripening, and in storage. We examined the tritrophic effects of 5 pistachio cultivars, representing the full range of kernel suitability for E. ceratoniae, on 2 larval parasitoids, Habrobracon hebetor (Say) (Hymenoptera: Braconidae), a gregarious, synovigenic, idiobiont, ectoparasitoid, and Venturia canescens Gravenhorst (Hymenoptera: Ichneumonidae), a solitary, pro-ovigenic, koinobiont, endoparasitoid...

A new species, Priopoda macrophyae sp. nov., is described. This species is an important parasitoid of a serious pest of Japanese ash (Fraxinus japonica), Macrophya satoi Shinohara & Li, 2015. This species resembles P. otaruensis (Uchida, 1930) in the black colouration of the hind coxa, hind femur, and all metasomal tergites, but can be clearly distinguished by the length of the malar space, the smooth interspace of the punctures on the mesopleuron, the large smooth area of the speculum, the complete and strongly raised propodeal carinae, and the length of the first metasomal tergite...

The Japanese species of the genus Leptobatopsis Ashmead, 1900 are revised. A total of eight species are recorded from Japan, including a new species, Leptobatopsis yaima sp. nov., and three species, L. annularis Kasparyan, 2007, L. koreana Lee & Kang, 2015, and L. nigricapitis Chandra & Gupta, 1977, newly recorded from Japan. A Chinese species L. annularis Sheng & Sun, 2013 is a homonym of L. annularis Kasparyan, 2007. Both species are clearly different, and we therefore propose a new replacement name for the former, L...
