Larval infestation rates on susceptible wheat tended to show the same patterns as oviposition rates (fig. 2). The level of infestation varied with location ranging from 3.0 to 97.2 flies per kg of fruit. However, cattle producers used to controlling tick infestations with chemical acaricides typically treat reactively. The role of the integrated host stress response in ectoparasite infestation is critical for understanding reduced parasite settlement and elimination of attached parasites. A prerequisite for this is a minimum of variation among hosts in the time from infestation to elimination of the parasites. Such elimination of infestation sources by means of a biological control agent might be more economic than by manual labour. The study of the biology suggested that infestation might be checked by delaying harvesting until after the larvae hatched. Infestation-based discrimination among seeds is of great potential relevance for the population dynamics of the plants and the insects, as well as the vertebrates, involved. The result was that the abandoned fields served as permanent foci of infestation throughout the island. For this reason, reliance on insecticides as the sole means of managing infestations was considered at best a short term solution. Antibiosis was estimated as the biomass accumulated by each aphid species on each accession during infestation. These properties define the patch-specific longterm probability of occupancy or, in this case, the probability of an infestation being established and maintained. This was explained to the volunteers, and every single one expressed his willingness to submit to prolonged infestation with the itch mites. The snails were characterized and the prevalence of their infestation by schistosomes was investigated. Three days after the infestation, the number and weight of surviving aphids on each plant were recorded. Ten pesticide applications were made to avoid shedding of fruiting organs due to insect infestation. Ten pesticide treatments were applied to avoid shedding of fruiting organs due to insect infestation. An infestation might well damage poultry farms and fisheries, but it was for the industries to protect their stock as best they could. Further study is needed to determine whether wasp infestation influences pathogen infection in ticks. Early detection is essential to stop infestation and work is underway to develop systems capable of detecting early instar larvae. These effects became particularly marked following the 5th or 6th successive infestations in lambs. As such, the host-parasite interaction significantly affects the development of infestations and therefore the potential for transfer of the parasite or gene flow between populations. A soil insecticide was applied to plots at different times during the tillering phase of rice in order to manipulate the timing of weevil infestation.
