摘要: Publisher Summary This chapter summarizes the evidence that parasitoid viruses function as endocrine regulators in host–parasitoid–polydnavirus relationship and ultimately act disruptors leading to death of host. Parasitoids are insect parasites kill their host prior its reproductive stage. Killing is essence being a parasitoid. Hence this explains exploitation biological control reduce pest populations. Many species parasitized lepidopteran larvae developmentally arrested terminal instar when parasitoids emerge normal signals accompanying pupation suppressed. Additionally, stops feeding emergence from anorexia irreversible. host–parasitoid systems described deals with larval–larval or egg–larval parasitoids. Because continues feed molt following parasitization, these braconid classified koinobionts.
