Feeding Preference and Foraging Behaviour of Eriopis connexa on Two Aphid Species
ABSTRACT Aphids are phloem‐feeding insects that cause both direct and indirect damage to crops, reducing agricultural productivity. Among the available pest control strategies, biological control using natural enemies is a sustainable and effective approach. The ladybird Eriopis connexa (Germar, 1824) is a generalist predator known for its voracity and

Evolution of crop phenotypic spaces through domestication
Summary We used domestication as an in vivo replicated experiment to investigate how divergent selection has shaped the evolution of multivariate phenotypic spaces. We measured 11–57 qualitative and quantitative traits in 13 species, either unique or shared between species, and established a framework for cross‐species comparisons. Our results revealed

ABSTRACT A key challenge for the genetic improvement of canola (Brassica napus), one of the world's most important oilseeds, is the limited natural variation for commercially important traits. The creation of new variation is hindered by the lack of functional knowledge about genes controlling these traits.

Glucosinolate types and concentrations in seedlings of different Brassica species used for food [PDF]
Brassicaceous food crops contain in their tissues different quantities of the glucoside allelochemicals known as glucosinolates (Bellostas et al., 2004; Sørensen, 1990).

Qualitative and quantitative evaluation of glucosinolates in cruciferous plants during their life cycles [PDF]
Glucosinolates produced by Brassica species were investigated in relation to biofumigation, a term used to describe the effects some allelochemicals, including glucosinolate derived products, may have on soil-borne pathogens or other herbivores.
