It is implicitly assumed here that there is no residual insecticidal effect of the control operation.
These dormant stages could be subject to natural mortality but were free of insecticidal effects.
In fact, product tolerance is generally the limiting factor in developing an effective insecticidal controlled atmosphere treatment.
Nevertheless, the results do suggest that insecticidal impact modelled under constant favourable conditions (table 2) could understate substantially the real risks in fluctuating ecological circumstances.
Thus, non-target insects that are coprophagous (for all or part of their life cycle) may consequently be exposed to insecticidal residues in dung.
While such biotype-plant affinities may suggest specific adaptations, they can also reflect the insecticidal history of the crops.
Transgenic plants expressing insecticidal toxins offer a completely new approach to stem borer control.
Furthermore, the late instar larvae thriving inside the stem are inaccessible to insecticidal sprays.
Insecticidal treatment of nursery stock could be considered, however, to avoid planting out stressed trees during the susceptible establishment phase.
These limitations on the use of amorphous silica as a blatticide have been overcome to some extent by the incorporation of additional insecticidal components into commercial silica-based formulations.
