The rearing of beneficial insects
New Zealand Entomologist, 1982Rearing of beneficial insects encompasses the synchronisation of 3 biological entities—the beneficial species, its host species, and the host plant or food. The purposes of rearing beneficial insects (parasitoids and predators) in the laboratory may be to study the insect itself, to facilitate the establishment of an introduced species, to accomplish a

The benefits that insects offer to nature and humans are as diverse as they are inestimable. Insects pollinate plants, thus enabling many cycles to take place in our ecosystem in the first place. They are growth accelerators and make an essential contribution to the diversity of species and habitats (the so-called biodiversity).

Microencapsulated Medicines for Beneficial Insects
2003Few veterinary medicines are used for treating invertebrate micro-livestock. We made and tested a specially designed microcapsulated medicament that disguised antifeedant properties of active ingredients and were of appropriate, ingestable sizes to enter the alimentary tracts where the active ingredient was liberated.

Dissemination of beneficial microbial agents by insects
2000Recent trends in pest management show an increased shift from insecticidal sprays towards the use of transgenic crops with insecticidal properties. This shift is partly due to the development of insect resistance to conventional insecticides and the large and increasing costs of developing and registering new chemicals.

Beneficial Insects and Insect Pollinators on Milkweed in South Georgia
Journal of Entomological Science, 2009A study was conducted to monitor feeding activity of beneficial insects and insect pollators on nectar of tropical milkweed Asclepias curassavica near a maize field in Georgia, USA. Insects visiting these milkweed plants were observed weekly throughout the maize-growing season in 2008. Each plant was observed for 2 minutes on an hourly basis from 09.00
