A new technique has been applied to coincidence measurements between fission fragments (FF) and intermediate mass fragments (IMF) emitted from the composite system 149 65 Tb at an excitation energy of 224 MeV. The method permits simultaneous observat

The effectiveness of biofumigant defatted seed meals and plants to control wireworm populations (Agriotes brevis Candeze, Agriotes sordidus Illiger, and Agriotes ustulatus Schaller) was evaluated under both semi-natural (pot assays) and field conditi

1. Aphid populations on agricultural crops in temperature regions collapse over a few days from peak numbers to local extinction soon after mid-summer (e.g. mid-July in the U.K.). The populations recover 6–8 weeks later. There is anecdotal or incid

Populations of many phloem-feeding aphid species in temperate regions increase exponentially in early summer and then ‘disappear’, usually over a time-scale of a few days, in July. To understand these dynamics, empirical investigation of the caus

SUMMARYTo define plant `nutritional quality' for aphids, the causal basis of the variation in aphid performance between host plants of different developmental ages was explored using the aphids Myzus persicae and Macrosiphum euphorbiae on potato plan

Light charged particles (LCP) have been measured for the reaction 344 MeV 28 Si + 121 Sb in singles and in coincidence with evaporation residues (ER), fusion–fission fragments (FF), and other LCP. A major feature of this experiment was the use of a

The use of vegetable and cereal food baits as an alternative to soil sampling for detecting wireworms ( Agriotes spp.) in field soils was investigated in two field experiments in 1993. A simple cereal-baited trap was found to be at least as effective
