These surveys highlight the existence of a rich naturalenemy guild that is keeping the pest in check in its natural habitat. The naturalenemy exclusion experiment (fig. 6) indicated that the decline in aphid numbers was due, in large part, to increased naturalenemy activity. This approach provided powerful support for the conclusions from the field study that both plant and naturalenemy factors contribute to the aphid population decline. The presence of fungus had no significant effect on thrips predation by either of the naturalenemy species. Effects of weeds on selected arthropod herbivore and naturalenemy populations, and on cotton growth and yield. The management treatments led to varying insectivory rates and daily predation patterns, suggesting that naturalenemy communities behaved differently in the assorted cropping systems. A greater understanding of naturalenemy behaviour is essential before enhanced control of pest populations in the field can be established. Further study is required for accurate quantification of naturalenemy abundance and activity levels, particularly for nocturnally-active species. It is thus unlikely that naturalenemy avoidance played a role here. Indeed, this is what would be expected when a single generalist predator is studied in a highly complex naturalenemy system. As a consequence, observed variations in insect abundance might be attributed to the combination of both host plant quality and naturalenemy factors. Furthermore, naturalenemy and plant factors can interact synergistically to alter aphid performance. The remaining three trays were left as naturalenemy-free controls, but were sprayed in the same way. This approach exploits the differences in time scales observed between host plant, aphid, and naturalenemy dynamics. Second, knowledge of the pest's life cycle will assist with timings of naturalenemy releases or application of selective pesticides in orchards. They don't want to face their naturalenemy, man. Despite efforts by some in recent years to develop more consensual approaches to industrial sectors, many national environmental bureaucrats see these as their 'naturalenemy'. Classical biological control includes the recognition, evaluation and importation of a natural enemy from elsewhere, the conservation of local natural enemies and the augmentation of the biocontrol agents. Naturalenemy population trends were rarely significant; therefore no general statements can be made. These examples are from corpora and from sources on the web.
