The effects of infection by a microsporidium, Vairimorpha necatrix (Kramer), on the endogenous levels of juvenile hormones in tomato moth (Lacanobia oleracea L.) larvae were investigated. Levels of juvenile hormone II (JH II) were 10-fold greater in

Commodities may be attacked by a multitude of pest species simultaneously and so to be cost-effective any lure must be attractive to a range of target species. The objective of this study was to test a multi-species lure formulation with different di

Chemicals used in communication are divided into signals and cues. Signals are moulded by natural selection to carry specific meanings in specific contexts. Cues, on the other hand, have not been moulded by natural selection to carry specific informa

The objective of this study was to identify the attractive components of a carob–peanut extract which is known to be attractive to the three principal grain beetle pests in the UK (Oryzaephilus surinamensis, Sitophilus granarius and Cryptolestes fe

Methods for detecting and discriminating volatile organic compounds emitted by statutory pathogens in potato tubers are reported. Analyses were performed utilising headspace solid phase microextraction gas chromatography–mass spectrometry (HS-SPME-

Foodstuffs give rise to complex volatile profiles which may consist of several hundred components. Determination of the key components that elicit specific insect behaviour enables simplification of constituents for incorporation into attractive lure

The behavioural responses of Sitophilus granarius , S. oryzae and S. zeamais to synthetic 4S,5R-sitophinone alone and in combination with volatiles from kibbled carob have been investigated with a view to the development of a single lure to attract a

The most likely entry pathways of veterinary pharmaceuticals to the environment are via slurry or manure from intensively reared animals to soil and via dung or urine from animals grazing on pasture. These pathways may result in contamination of surf

Experiments examined the accepted modes of action of the desiccant dust, diatomaceous earth (DE), against the flour mite, Acarus siro (L.) (Astigmata). Adult mites were exposed to three DE products for periods of 3, 18 and 72 h under conditions desig

Several authors have suggested that edible plants could avoid herbivory by mimicking olfactory cues of toxic plants. However, very few studies have been carried out to test this hypothesis. The aims of the present study were to identify the volatiles
