Improving the cost-effectiveness, trade and safety of biological control for agricultural insect pests using nuclear techniques
An FAO/IAEA Coordinated Research Project (CRP) addressed constraints related to costly production systems for biological control agents, and the presence of accompanying pest organisms during their shipment, and demonstrated the feasibility of integrating augmentative and sterile insect releases in area-wide IPM programmes.

Survival at low temperature of larvae of the pine processionary moth Thaumetopoea pityocampa from an area of range expansion
Investigating the survival at low temperature of larvae originating from a population with range expansion in an alpine valley in Northern Italy found that feeding activity and survival can be impaired by adverse climatic factors. Expand

Vertical transmission and the overwintering success of three different microsporidia infecting Lymantria dispar larvae were investigated, finding the infectivity of spores that overwintered in cadavers of infected L. dispar varied by species, placement in the environment, and weather conditions.

Horizontal transmission pathways of terrestrial microsporidia: A quantitative comparison of three pathogens infecting different organs in Lymantria dispar L. (Lep.: Lymantriidae) larvae
Pathways for horizontal transmission of three microsporidian species, such as transmission via silk, feces, cadaver, exuviae and direct contact, were studied in Lymantria dispar larvae, finding that the release of spores from decomposing cadavers is the main transmission pathway. Expand
Interactions between an entomopathogenic microsporidium and the endoparasitoid Glyptapanteles liparidis within their host, the gypsy moth larva.
Host selection experiments revealed that G. liparidis females did not discriminate between infected and uninfected host larvae for oviposition, and negative effects of host infection on Parasitoid larvae were detectable from the beginning of parasitoid larval development. Expand
Low temperature tolerance and starvation ability of the oak processionary moth: implications in a context of increasing epidemics
It is concluded that, in the oak processionary moth, neonate larvae are relatively well adapted to early hatching relative to budburst, ensuring them the highest foliage quality for development. Expand
Impact of predators on artificially augmented populations of Lymantria dispar L. pupae (Lep., Lymantriidae)
Spatial differences in predation were ascertained, suggesting that the aggregation of small mammals, for example, is related to patches of dense shrub vegetation. Expand
Vairimorpha disparis n. comb. (Microsporidia: Burenellidae): A Redescription and Taxonomic Revision of Thelohania disparis Timofejeva 1956, a Microsporidian Parasite of the Gypsy Moth Lymantria
The octospores of certain microsporidia infecting Lepidoptera that were previously described as Thelohania spp. Expand
Alterations in carbohydrate and fatty acid levels of Lymantria dispar larvae caused by a microsporidian infection and potential adverse effects on a co-occurring endoparasitoid, Glyptapanteles
It is concluded that the microsporidia-induced decrease in hemolymph carbohydrates and fatty acids adversely affects growth and development of parasitoid larvae. Expand
