Abstract BACKGROUND The Japanese giant silkworm (JGS) Caligula japonica is a significant defoliator pest in East Asia, causing severe economic losses forest and fruit production. To establish cost‐effective biological control program against JGS, the age‐stage, two‐sex life table method was used to accurately assess potential efficacy of two Mesocomys species ( M. albitarsis trabalae ) controlling this pest. Our study focused on functional response Chinese oak (COS) Antheraea pernyi eggs (factitious host), as well their reproductive attributes when exposed JGS (target host). RESULTS Both exhibited type II increasing densities COS eggs. Mutual interference greater than that at high parasitoid densities. Two parasitoids reared from effectively parasitized eggs, albeit with differing parasitism capacities. had an average fecundity 190.4 offspring, which 3.8‐fold higher .

Abstract Biological control is a pest method that can offer an environmentally safer alternative to chemical pesticides. The proven safety record of both augmentative and classical biological technologies allows its utilization against indigenous non‐indigenous but well‐established pests, whether under protected conditions (e.g., glasshouses) or in open field cropping systems.

ABSTRACT Insects have evolved a spectrum of strategies that facilitate survival in the face adverse environmental conditions and bottom‐up or top‐down pressures. The egg is first stage life cycle most insects. It not only immobile but many insects survives unfavourable seasons when food resources are unavailable. Eggs targeted by oophagous natural enemies also subject to abiotic stresses. In response these diverse stresses, developed various protection strategies. Females lay eggs clusters then use their own body cover them provide from harsh environments biotic attack. Such allowed some herbivorous thrive new become serious invasive pests. protect other ways (e.g. laying concealed places, direct parental care) while others do at all.

Abstract Background Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is an invasive pest that can cause serious crop loss to various important food crops and risk global security. FAW damage over 350 plant species by feeding on vegetative reproductive stages of crops. Currently, chemical pesticides transgenic maize are widely used safeguard from this pest. However, biological control a safer more sustainable alternative in the long term for management. Of natural enemies FAW, egg parasitoids genus Trichogramma have been augmentative Americas invaded regions such as Africa Asia. Main body Several reported naturally parasitizing eggs emerged biocontrol agents. This paper presents comprehensive review potential challenges associated with FAW. A total 11 trichogrammatids occurred eggs. includes occurrence attributes, mass rearing, release techniques, field efficacy interaction integration other parasitoids.

Abstract Background Fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is one of the new alien destructive pests maize and other 350 economic crops. The majority farmers are still depended upon chemical insecticides to suppress pest, but S. has succeeded develop resistance against most families. Improving an effective environmentally-friendly approach highly recommended. Therefore, egg parasitoids best weapon for managing FAW in early stage due feeding behavior their larvae. In this regard, impact mass layers scale thicknesses, as physical barriers, on parasitic performance egg-parasitoid species, Trichogrammatoidea bactrae Nagaraja (Hymenoptera: Trichogrammatidae), non-choice choice tests was assessed. Besides, efficacy FAW-produced adult wasps next generation based rates parasitism, adults' emergence, female progeny determined.
