Over 10 years of field trials show reductions of most of the pests in Brassicas undersown by clover. The pest-reducing effects are due to the 'appropriate / inappropriate landings' hypothesis (Finch, 1996), and the 'host plant quality' hypothesis (Th

Summary 1 In two successive years, the olfactory responses of Pterostichus melanarius Illiger (Coleoptera: Carabidae) to intact cabbage and white clover plants were studied, using a four-arm olfactometer. 2 The first set of experiments tested the res

Five genotypes of swede (Brassica napus var. napobrassica), two genotypes of kale (B. oleracea var. acephala), and two genotypes of rape (B. napus var. napus) were each inoculated at the 8-10 true leaf stage with five cabbage root fly (Delia radicum)

The post-alighting behaviour of gravid female turnip root fly, Delia floralis (Fallen) (Diptera: Anthomyiidae), was observed in the laboratory, using four plant genotypes differing in antixenotic resistance, to stimulate a range of oviposition-relate

Populations of the mealy cabbage aphid, Brevicoryne brassicae (L.), on Brussels sprout plants, Brassica oleracea (L.) were sampled, fortnightly throughout the early season of 1996, in 2 ha 2 blocks. Sampling was done on two spatial scales, firstly ov

Peach potato aphids Myzus persicae (Sulzer) (Homoptera: Aphididae) were reared on artificial diets containing the steroidal glycoalkaloids (GAs) α-solanine and α-chaconine in concentrations lower or similar to those observed in potato leaves. The a

The effect of increasing herbivore pressure, in the form of larval feeding damage by the turnip root fly, Delia floralis, on the glucosinolate content of swede roots (Brassica napus ssp. rapifera) was investigated. Only one of the 14 root glucosinola

The role of leaf surface compounds influencing the oviposition of the turnip root fly, Delia floralis, was investigated using bioassays and fractionation of leaf surface extracts from four Brassica genotypes. Polar leaf surface extracts contained bet

Intercropping has potential as an alternative to chemical methods of pest control, and one of its effects may be to provide a favourable environment for beneficial invertebrates, including polyphagous predators such as carabid beetles (Coleoptera: Ca

The decision to oviposit on or reject a plant is central to the evolution and maintenance of insect host range. However, detailed analyses of oviposition sequences are uncommon. Important information can be retrieved from behavioural sequences of ind
