The introduction of the Asian gypsy moth into novel environments continues with frequent interceptions in North America. There is a concern that these subspecies will pose greater threat to forests and urban America than established moths (Lymantria dispardispar L.), due their capacity for female flight. populations vary many key traits, including flight capabilities. potential impacts flight, ...

The Lymantria dispar nucleopolyhedrovirus (LdMNPV) gene encoding the 25K FP protein has been cloned and sequenced. The 25K FP gene codes for a 217 amino acid protein with a predicted molecular mass of 24870 Da. Expression of the 25K FP protein in a rabbit reticulocyte system generated a 27 kDa protein, in close agreement with the molecular mass predicted from the nucleotide sequence. The gene i...

Biological control of gypsy moth ( Lymantria dispar ) was carried out in 2021 the field protective forest belts at territory State Hunting Enterprise Balchik by introducing entomopathogenic fungus Entomophaga maimaiga (Entomophthorales: Entomophthoraceae). In same year a mortality rate 26.1% pest population registered. 2022 E. and multiple nuclear polyhedrosis virus L Ld MNPV) caused collapse r...

Transgenic poplar lines 'Shanxin' (Populus davidiana×Populus bolleana) were generated via Agrobacterium-mediated transformation. The transgenic lines carried the expression cassettes of Cry1Ac + SCK, Cry1Ah3, and Cry9Aa3, respectively. The expression levels of the exogenous insect resistance genes in the transgenic lines were determined by Q-PCR and Western blot. Leaves of the transgenic lines ...

How the innate immune system functions to defend insects from viruses is an emerging field of study. We examined the impact of melanized encapsulation, a component of innate immunity that integrates both cellular and humoral immune responses, on the success of the baculovirus Lymantria dispar multiple nucleocapsid nucleopolyhedrovirus (LdMNPV) in its host L. dispar. L. dispar exhibits midgut-ba...
