“…Many studies have reported the use of dsRNA to down-regulate insect genes through feeding. Recently, dsRNA feeding was used for downregulating genes in insects, such as dsRNases of corn leafhopper, Dalbulus maidis ( 23 ) and the glutamate-gated chloride channel gene of the fall armyworm, Spodoptera frugiperda ( 24 ). Further, dsRNA is taken up through an active process involving receptor-mediated endocytosis in Drosophila emanogster S2 cells ( 25 ).…”

Parasitoid wasps control pests via a precise attack leading to the death of the pest. However, parasitoid larvae exhibit self-protection strategies against bracovirus-induced reactive oxygen species impairment. This has a detrimental effect on pest control. Here, we report a strategy for simulating Microplitis bicoloratus bracovirus using Mix-T dsRNA targeting 14 genes associated with transcription, translation, cell–cell communication, and humoral signaling pathways in the host, and from wasp extracellular superoxide dismutases. We implemented either one-time feeding to the younger instar larvae or spraying once on the corn leaves, to effectively control the invading pest Spodoptera frugiperda. This highlights the conserved principle of “biological pest control,” as elucidated by the triple interaction of parasitoid-bracovirus-host in a cooperation strategy of bracovirus against its pest host.

BACKGROUNDAphid infestation adversely affects the yield and quality of crops. Rapid reproduction and insecticidal resistance have made controlling aphids in the field challenging. Therefore, the present study investigated the insecticidal property of Penicillium oxalicum (QLhf‐1) and its mechanism of action against aphids, Hyalopterus arundimis Fabricius.RESULTSBioassay revealed that the control efficacy of the spores against aphids (86.30% and 89.05% on the third day and fifth day after infection, respectively) were higher than other components, such as the mycelium. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) showed that QLhf‐1 invaded the aphid cuticle through spores and used the aphid tissues as a nutrient source for growth and reproduction, causing stiffness and atrophy and a final death. Three extracellular enzymes, lipase, protease, and chitinase had a synergistic effect with spores, and they acted together to complete the infection process by degrading the aphid body wall and accelerating the infection process.CONCLUSIONThe newly discovered endophytic penicillin strain P. oxalicum ‘QLhf‐1’ can effectively kill aphids. The results provided strong evidence for the biological control of aphids, and lay a foundation for the development and utilization of QLhf‐1. © 2024 Society of Chemical Industry.
