Successful Control

AbstractThe potential distribution of the South African weevil, Perapion antiquum (Gyllenhal), a biological control agent for the weeds Emex spp., was deter mined by the computer program CLIMEX, using its native distribution, phenology and abundance together with development parameters. The predicted distribution included parts of Hawaii where the weevil successfully controlled Emex australis and E. spinosa. In Australia, sites of past unsuccessful releases have climates that this analysis indicates are unsuitable for the insect. The most favourable regions for establishment of the weevil are near the coast in the southern half of Australia, but most of these do not overlap with regions where Emex spp. are a problem. In western Cape Province, South Africa, E. australis plants are abundant and the weevil attacks the plant after seeds have formed. In Hawaii, a fortuitous combination of climatic conditions favours the weevil during the period after seed germination, and this may be the key to its control of the weed. Sites with climatic conditions similar to successful control sites in Hawaii are not found in Australia. It was concluded that P. antiquum will be of limited use as a biological control agent in Australia even in areas suitable for its establishment.

Two strains of Microctonus aethiopoides with differing host preferences have been released in New Zealand The first was released in 1982 to suppress Sitona discoideus a pest of lucerne and the second was released in 2006 for biological control of Sitona lepidus This paper describes three genetic approaches (esterase isozymes aldehyde oxidase allozymes and nucleotide sequences in a 676 bp region of the mitochondrial cytochrome oxidase subunit one gene) for distinguishing between the M aethiopoides strains A range of research applications for these methods is discussed

Different Populations

AbstractLaboratory studies were carried out on different populations of Aphidius ervi Hal., A. picipes (Nees) and A. rhopalosiphi De Stef. collected in England from Acyrthosiphon pisum (Harris), Sitobion spp., Microlophium carnosum (Buckt.) and Metopolophium dirhodum (Wlk.). When mated females from each population were confined separately with 4–5 other species of these and other genera, each population varied in their host preferences, even though individual populations of each species were electrophoretically and morphometrically homogeneous. These host preferences differed in terms of fecundity. Different populations of Aphidius ervi exhibited markedly different host ranges. This behaviour is probably conditioned rather than inherited, and its significance to biological control is discussed. The results suggest a need to assess quantitatively the effect of temperature, host size and host species on the parasitoids' ability to control pest aphids.
