Manipulation of predator chemical ecology by the inclusion of behavior-modifying compounds in a crop spray mix with reduced amounts of insecticide may allow for efficient aphid control with less environmental contamination. Expand
Electrophoresis as a tool for estimating levels of hymenopterous parasitism in field populations of the cereal aphid, Sitobion avenue
Electrophoresis was found to be a much quicker method than live‐rearing and gave similar results for both levels of parasitism and parasitoid species composition, whereas mummy counts tended to give lower estimates than the other two methods. Expand
Flight periodicity and infestation size of Sitona lineatus
Examination of the yields of field experiments at Rothamsted demonstrate an unexpected trend for higher yields in later sown spring bean crops, which may be because late sowing avoids infestation by spring migrants. Expand
Distant olfactory response of the cabbage seed weevil, Ceutorhynchus assimilis, to oilseed rape odour in the field
It is suggested that seed weevils can use odour‐mediated upwind anemotaxis to locate their host‐plants from distances of at least 20 m. Expand
Prey preferences of six species of Carabidae (Coleoptera) and one Lycosidae (Araneae) commonly found in UK arable crop fields
Abstract: Laboratory experiments were used to determine the feeding preferences of six carabid beetles and one lycosid spider on aphid and collembolan prey. The first investigation used only five… Expand
Electroantennogram responses of the cabbage seed weevil,Ceutorhynchus assimilis, to oilseed rape,Brassica napus ssp.Oleifera, volatiles
Electroantennograms (EAGs) were recorded from male and female cabbage seed weevils in response to volatiles isolated and identified from the odor of oilseed rape and several terpenes present in rape flower odor. Expand
Laboratory and field response of the pollen beetle, Meligethes aeneus, to the odour of oilseed rape
Pollen beetles can use odour‐mediated upwind anemotaxis to locate oilseed rape plants from distances of at least 20 m over open ground. Expand
Prey selection and foraging behaviour by Pterostichus cupreus L. (Col., Carabidae) under laboratory conditions
Abstract: Several authors have indicated that carabid beetles offer potential as predators of insect pests on arable crops, but this potential is reduced by their limited ability to climb the crop… Expand
CABBAGE APHID (BREVICORYNE BRASSICAE. L.) âPERFORMANCEâ ON OILSEED RAPE (BRASSICA NAPUS. L.) EXPERIENCING WATER DEFICITS: ROLES OF TEMPERATURE AND FOOD QUALITY.
Larval instar determination of the pea and bean weevil Sitona lineatus L. (Coleoptera: Curculionidae).
Head-capsule measurements on larvae of Sitona lineatus (L.) collected on beans (Vicia faba) in southern England in 1980 showed that there were 5 larval instars. Final-instar larvae, pupae and adults… Expand
