Abstract

The large-scale production of Baculovirus to control fall armyworm, Spodoptera frugiperda, presents many limitations. The most important limiting factor is that the baculovirus, which infects fall armyworm, causes liquefaction of the integument immediately after death.

Highlights

NOVO ISOLADO DE BACULOVÍRUS QUE NÃO CAUSA LIQUEFAÇÃO DO INTEGUMENTO EM LARVAS MORTAS DE Spodoptera frugiperda
The use of chemical insecticides to control S. frugiperda has increased over the years, reaching in some producing regions 10 to 14 applications to control this insect in corn (Valicente, personal observation)
Valicente (1989) sampled more than 14.000 larvae from Minas Gerais State/ Brazil and a high percentage of parasitism was found in some areas, and several Baculovirus isolates, including nucleopolyhedrovirusNPV and granulovirus-GV

Summary

Introduction

NOVO ISOLADO DE BACULOVÍRUS QUE NÃO CAUSA LIQUEFAÇÃO DO INTEGUMENTO EM LARVAS MORTAS DE Spodoptera frugiperda. Spodoptera frugiperda (J.E. Smith), is one of the most important maize insect pests in Brazil and its damage may reduce yield up to 52% (Cruz et al 1996, 1999; Figueiredo et al 2006). Valicente & Cruz (1991) recommended isolate 18 (disrupts the integument of dead insects) to be used into the Maize Insect Pest Management (IPM) program, large scale production has many limitations.
