Biological control of pests in the field - a possibility? - A survey of aphids and parasitoids in cereals


, : Biological control of pests in the field - a possibility? - A survey of aphids and parasitoids in cereals. SP Rapport Statens Planteavlsforsog ( 8): 149-158

A survey of the abundance and species composition of cereal aphid (Sitobion avenae, Rhopalosiphum padi and Metopolophium dirhodum) primary and secondary parasitoids was conducted in spring barley, winter wheat and durum wheat fields in Denmark during 1996 with the aim of gaining a better understanding of the mechanisms underlying aphid-parasitoid dynamics (which will be useful when developing biological control methods).

The dorsal ectoderm of the limb bud is known to regulate anterior-posterior patterning as well as dorsal-ventral patterning during vertebrate limb morphogenesis. Wnt-7a, expressed in the dorsal ectoderm, encodes a key molecule implicated in these...

The addition of 1-50 mM MgCl2 to low salt [pea] thylakoid membranes causes a monotonic decrease in the transverse, aqueous proton relaxation rate (R.2) and an increase in the 6-line ESR spectrum characteristic of free Mn(II) but does not affect th...

The flash-induced thermoluminescence (TL) technique was used to investigate the action of N,N,N',N'-tetramethyl p-phenylenediamine (TMPD) on charge recombination in photosystem II (PSII). Addition of low concentrations (mu M range) of T...

To assess contaminant concentrations in the Firth of Clyde in relation to the former sewage sludge dump site at Garroch Head, and investigate any temporal changes, fish have been sampled annually since 1992 and sediment since 1999. In addition, a...

In connection with the introduction of the non-ionic radiographic contrast medium metrizamide (Amipaque), no significant albumin binding of metrizamide could be revealed by the use of equilibrium dialysis. The protein binding of metrizamide was in...
