A range of nuclear magnetic resonance (NMR) techniques, 1H liquid spectroscopy and T1 and T2 relaxation measurements, and microimaging, have been used to observe changes taking place within the bodies of live samples of Coccinella septempunctata, und

Dinocampus coccinellae females which eclose in mid-summer have the opportunity to oviposit in overwintered or in newly eclosed coccinellid hosts. Given the short further longevity of overwintered hosts, offspring fitness would be increased by oviposi

Summary Foliage of potato cv. Desiree was harvested from glasshouse-cultivated plants of five experimental transgenic lines expressing three different insecticidal proteins (snowdrop lectin, Galanthus nivalis agglutinin (GNA); jackbean lectin, Concan

We investigated if the activity of soil invertebrates (protozoa and earthworms) affected the performance of barley and if effects propagated higher up the above-ground food chain into herbivores (cereal aphid, Sitobion avenae). Barley plants were gro

Ladybirds have a certain fascination to children, making them an ideal tool to aid the teaching of biological science. They are accessible and amenable to study, and a wide variety of topics can be investigated, for example, insect life cycle, parasi

Summary 1. Two lectins, concanavalin A (Con A) and Galanthus nivalis agglutinin (GNA), have anti-feedant properties that suggest a potential for the control of invertebrate pests of plants. We tested potato plants genetically engineered to produce ea

Transgenic crops genetically engineered for enhanced insect resistance should be compatible with other components of IPM for the pest resistance to be durable and effective. An experimental potato line was genetically engineered to express an anti-ap

The effects of concanavalin A (ConA), a glucose/mannose-specific lectin from jackbean (Canavalia ensiformis), on insect crop pests from two different orders, Lepidoptera and Homoptera, were investigated. When fed to larvae of tomato moth (Lacanobia o

Proteinase activities in the midguts of adult and larval two-spot ladybirds were investigated. Both extracts showed a slightly acidic pH optimum for proteolysis against azocasein (pH 6.0 and pH 5.5 for larvae and adults respectively), which correlate
