Ocorrência de Baculovirus em Lagartas de Perigonia lusca (Fabr.) (Lep., Sphingidae) no Brasil

Abstract

Occurrence of Baculovirus on Perigonia lusca (Fabricius) (Lepidoptera, Sphingidae) Larvae in Brazil ABSTRACT-A large number of dead Perigonia lusca (Lepidoptera, Sphingidae) larvae were observed in "Paraguay tea" (Ilex paraguariensis) plantations in the West of Paraná State. Live insects were collected from these fields, maintained on "Paraguay tea" leaves in laboratory and observed daily. The dead larvae were macerated and the resulting suspension was observed under microscope. Occlusion bodies typical of the Baculoviridae family were observed. The pathogenicity of the virus was confirmed by following procedures outlined in Koch's postulates. This is the first register of a virus in Perigonia lusca in Brazil.

Baculovirus Insecticides in Latin America: Historical Overview, Current Status and Future Perspectives

“…This pest was observed in Argentina, Paraguay [ 159 ], and Brazil [ 160 ]. The damage caused by P. lusca increased following the introduction of the monoculture in response to the increasing demands of yerba mate in South American countries [ 161 ]. A baculovirus ( Perigonia lusca SNPV) was isolated from this species first in Argentina [ 162 ] and later in Brazil [ 161 ].…”

“…The damage caused by P. lusca increased following the introduction of the monoculture in response to the increasing demands of yerba mate in South American countries [ 161 ]. A baculovirus ( Perigonia lusca SNPV) was isolated from this species first in Argentina [ 162 ] and later in Brazil [ 161 ]. It has been successfully used by farmers as a crude preparation, in over 2500 ha of yerba mate plantations, at a dose equivalent to 15 infected last instar larvae per hectare [ 159 , 162 ].…”

“…Atacam também abacateiro, mangueira, cafeeiro e nogueira (Penteado et al, 2000e Gallo et al, 2002. Dois picos populacionais anuais são verificados nos meses de setembro e janeiro, coincidindo com os menores índices pluviométricos do ano e com a ocorrência de folhas maduras no campo, respectivamente (Alves et al, 2001). Com seus estiletes, perfuram as folhas, extravasando e sugando o conteúdo das células.…”
