A New Cypovirus-1 Strain as a Promising Agent for Lepidopteran Pest Control

Abstract

In this article, we describe a newly discovered cypovirus strain that displays features ideally suited for the development of a modern biological insecticide: high potency, relatively broad host range, true regulating effect, flexible production (possibility to choose host species for production), interaction with enhancing adjuvants, and ecologically friendly. Based on an alignment of CPV genomes, we suggest that the enhanced host range of this new strain is the sequence of evolutionary events that occurred after coinfections involving different CPV species within the same host.

The Impact of a Cypovirus on Parental and Filial Generations of Lymantria dispar L.

“…DsCPV-1 is a potential biocontrol agent for several lepidopteran species [18]. The results of the current study provide valuable insights into the virulence of DsCPV-1 against L. dispar larvae and its direct and indirect impact on both the infected and subsequent generation of L. dispar.…”

“…DsCPV-1 OBs were isolated from cadavers of D. sibiricus larvae. A detailed description is presented in [18]. Briefly, the D. sibiricus larval cadavers were homogenized in sterile wa-ter, filtered through three layers of cheesecloth, and centrifuged at 20,000× g for 20 min.…”

“…In a recent study, we isolated and investigated a new cypovirus from naturally infected Dendrolimus sibiricus larvae (DsCPV-1) [18]. In the present work, we studied DsCPV-1 against L. dispar larvae, and then estimated the impact on surviving parents and an indirect impact on a filial generation of L. dispar.…”
