Linking behavioural phenotypes to their underlying genotypes is crucial for uncovering the mechanisms that underpin behaviour and for understanding the origins and maintenance of genetic variation in behaviour. Recently, interest has begun to focus on the transcriptome as a route for identifying genes and gene pathways associated with behaviour. For many behavioural traits studied at the phenot...

Plant essential oils are being increasingly studied as a potential environmentally friendly alternative to synthetic insecticides. The insecticidal efficacy of on the cabbage seedpod weevil ( Ceutorhynchus obstrictus ), an important oilseed rape pest, has not been previously tested. We examined impact six C . via contact with dry residues leaf and flower surfaces. also effect these model non-ta...

Abstract Necrophagous flies are of great importance for human and animal health. In places where their development occurs, parasitoids can be used as a tool to control these dipterans. Brazil, the fauna has been investigated in some regions. However, Rio Grande do Sul, it is known occurrence only one species. Thus, this study aimed create first list medical veterinary Southern Brazil. Collectio...

Optimal foraging theory, specifically the marginal value theorem, predicts quicker leaving (shorter residence time) from poorer patches. One proximal mechanism for achieving the leaving is that exposure to lower-quality resources may trigger increased restlessness (proportion of time in locomotion). Which aspects of host quality, if any, affect restlessness was examined in females of the parasi...
