Feasibility of Using Cryostored Colorado Potato Beetle (Coleoptera: Chrysomelidae) Eggs for Rearing \u3ci\u3eEdovum Puttleri\u3c/i\u3e (Hymenoptera: Eulophidae) [PDF]
Cryostored eggs of Colorado potato beetle, Leptinotarsa decemlineata (Say) eggs were suitable hosts for Edovum puttleri. Parasitism rates were low, however this study was first to show that rearing the parasite on eggs stored at ultra low temperatures ...

Abstract This review provides a synthesis of the available knowledge on Carmenta foraseminis, an emerging cocoa pest in northern South America. This moth was first described in 1995 in Panama, and its proliferation across the Amazon basin is currently threatening the production of cocoa in the region and may endanger the sector's sustainability. Hence,

Does Wolbachia infection affect Trichogramma atopovirilia behaviour? [PDF]
Unisexual Trichogramma forms have attracted much attention due to their potential advantages as biocontrol agents. Fitness studies have been performed and understanding the cost that Wolbachia may inflict on their hosts will help in deciding if Wolbachia

Abstract Invasive eucalypt psyllids pose a threat to the long‐term production of eucalypts worldwide. In order to reduce their economic impact, classical biological control using Psyllaephagus species has been used successfully. The objectives of this study were to determine the host specificity and host stage preference of Psyllaephagus blastopsyllae,

Plant architecture and vegetation structure: Two ways for insect herbivores to escape parasitism
Interactions between herbivorous insects and their parasitoids occur in highly structured and complex environments. Habitat structure can be an important factor affecting ecological interactions between different trophic levels.

A New Host Record for the Egg Parasitoid Anagrus nigriventris (Hymenoptera: Mymaridae) of the Corn Leafhopper, Dalbulus maidis (Hemiptera: Cicadellidae) [PDF]
A survey of the eggs parasitoids of the corn leafhopper, Dalbulus maidis (DeLong & Wolcott) was carried out in Tucumán Province, Argentina. Samples were collected during the summer of 2004-2005 with sentinel eggs.

Stabilizing adaptation in an invasive species: Alfalfa weevil as a case study
Comparison of thermal thresholds, fecundity and longevity across three alfalfa weevil strains (California in the United States, Hamadan in Iran, Ebro Valley in Spain) reveal significant differences in demographic parameters. Weather‐driven physiologically based demographic models (PBDMs) developed from life table data explore strain adaptation to ...
