Hand rearing is a common procedure in behavioural research on birds. While likely to produce tamer experimental animals, there is a risk that it could induce pathological changes in brain and behaviour similar to those seen in mammals that have experienced maternal separation. We explored the effects of hand rearing on the cognitive and behavioural development of European starlings, Sturnus vul...

BACKGROUND & OBJECTIVES The treatment of wounds with live green bottle fly larvae is receiving considerable attention in many countries. Laboratory rearing of Lucilia sericata is crucially important for the treatment of wounds. STUDY DESIGN The study was carried out for mass rearing of green bottle flies from April to November 2010. Hand catch and net trap baited with beef and cattle liver we...

E€ects of geographical origin of strain, season of ®eld collection, genetic background, and number of generations of laboratory rearing on ̄ight initiation, body weight, and lipid content of lesser grain borer, Rhyzopertha dominica, were studied. Signi®cant di€erences in ̄ight initiation, body weight, and total lipid content occurred among the four ®eld strains collected from Kansas, Oklahoma, ...

The brown moth Thyrinteina arnobia (Stoll, 1872) (Lepidoptera: Geometridae) is an important pest in Brazilian eucalyptus plantations. A gynandromorph individual of T. arnobia was found in a population of this pest in a laboratory rearing and it is described.

Animal societies vary in the number of breeders per group, which affects many socially and ecologically relevant traits. In several social insect species, including our study species Formica selysi, the presence of either one or multiple reproducing females per colony is generally associated with differences in a suite of traits such as the body size of individuals. However, the proximate mecha...
