In contrast, biological control efforts directed towards controlling one pest may have no impact on other pestspecies. In pestspecies, gene flow is important in the evolution of insecticide resistance and adaptation to local environmental conditions. All the species sampled are from pest genera and all are pestspecies. There are many termite pestspecies in many different countries against which baits are deployed. The collected traps were examined in the laboratory and the pestspecies counted. The higher rate of pestspecies among non-indigenous faunas compared to indigenous faunas may be explained by three factors that are not mutually exclusive. The limited number of invertebrate pestspecies associated with mushroom cultivation increases the potential for adoption of a biological control strategy within this industry. However, the production of marketable eggplant is compromised due to numerous pestspecies that feed on eggplant. Among these components, natural enemies, weather conditions and host-plant attributes are the most important factors affecting population dynamics of pestspecies. As a conservative estimate, we assume an initial resistance level of 0.1 for the three pestspecies considered. Individual pestspecies can no longer be managed in isolation. Additionally, further studies are required to obtain a better understanding of resistance mechanisms affecting two or more insecticides within a single pestspecies. Furthermore, management options aimed at one pestspecies, particularly insecticide applications or cultural practices, may exacerbate problems with another species. The genus is important economically because many species are naturally-occurring regulating factors of pestspecies. Both crops received insecticide treatments to assess the crop loss by a pestspecies. This is especially important when dealing with pestspecies affecting a range of different cultivated and wild plants. The basic conclusion is of a differentiated population, with discrete and stable subpopulations, even in a continuous distribution of an extremely mobile pestspecies.
