Life history and population dynamics of Aspidiotus nerii (Bouche, 1833), Homoptera: Diaspididae, Saissetia oleae (Olivier, 1751), Homoptera: Lecanidae and Pollinia pollini (Costa, 1857), Homoptera: Asterolecanidae on olive trees in the Blida Region (Algeria)

Irradiation as a phytosanitary treatment for Aspidiotus destructor (Homoptera: Diaspididae).

Coconut scale, Aspidiotus destructor Signoret (Homoptera: Diaspididae), is a quarantine pest of banana (Musa spp.) and many tropical crops. Irradiation was examined as a potential phytosanitary treatment to control coconut scale. Dose-response tests were conducted with second-stage nymphs, adult females without eggs, and adult females with eggs at a series of irradiation doses between 60 and 20...

A guide to the winged aphids (Homoptera) of Costa Rica.

This guide is a compilation of limited morphological and biological information on the winged morphs of 60 species of aphids that have been collected in Costa Rica. It should not be viewed as a definitive taxonomic treatise on the aphids of Costa Rica, rather it is a tool that can be used to assist in research on the biology, host plant relationships, taxonomy, and virus transmission capabiliti...

The Phylogeny of the Homoptera

Collective Defense of Aphis nerii and Uroleucon hypochoeridis (Homoptera, Aphididae) against Natural Enemies

The prevalent way aphids accomplish colony defense against natural enemies is a mutualistic relationship with ants or the occurrence of a specialised soldier caste typical for eusocial aphids, or even both. Despite a group-living life style of those aphid species lacking these defense lines, communal defense against natural predators has not yet been observed there. Individuals of Aphis nerii (...
