Seven hypotheses, including the 'Resource Concentration Hypothesis' and the 'Enemies
Hypothesis', have been put forward to explain why fewer specialist insects are found on host …

Numerous studies have examined the responses of pest and beneficial arthropods to plant
diversification in ephemeral cropping habitats. Cruciferous crops, mainly cabbage and …

Vegetation complexity is characterized by two major traits, ie, plant chemical and plant
structural complexity. Plant species diversity strongly determines these traits. Furthermore …

There is growing public concern about pesticides' non-target effects on humans and other
organisms, and many pests have evolved resistance to some of the most commonly-used …

Push‐pull or stimulo‐deterrent cropping systems combine a trap crop or other attractant or
arrestant stimulus distant from the crop and a deterrent or repellent near or within the target …

Companion plants grown as 'trap crops' or 'intercrops' can be used to reduce insect
infestations in field crops. The ways in which such reductions are achieved are being …

Brassica and Allium host‐plants were each surrounded by four non‐host plants to determine
how background plants affected host‐plant finding by the cabbage root fly (Delia radicum L.) …

Laboratory and field‐cage tests were done to determine how undersowing brassica plants
(Brassica oleraceae L. and B. rapa L.)(Cruciferae) with subterranean clover (Trifolium …

Why are most herbivorous insects so specialized? How do generalists and specialists differ
ecologically? And what sensory and cognitive processes determine which host species an …

Brassica juncea is the most important oilseed crop in India, and Lipaphis erysimi is a major
pest of this crop. The study aimed at knowing the role of photosynthetic pigments in host …
