Effects of host plant characteristics on spray deposition

Previous studies have shown that the effect of Bacillus thuringiensis var kurstaki (Btk) on painted apple moth (PAM; Teia anartoides Walker) efficacy varies significantly depending on the host plant species This study tested the hypothesis that host plant architecture influenced deposition of aerially applied Btk and its consequent efficacy against PAM Laboratory experiments demonstrated that the architecture of six host plants had a significant influence on Btk dose per unit leaf area and dose per unit leaf weight However the large host plant effect on PAM mortality from Btk could not be explained in terms of variation in the amount of spray intercepted

A widespread interaction in natural enemy populations is intraguild predation (IGP), the intensity and outcome of which may be influenced by several factors. This study examined the influence of host plant characteristics on IGP between Orius albidipennis (Reuter) and Neoseiulus cucumeris (Oudemans) in laboratory experiments. The intraguild predation between the two predators was bi-directional, but predation by N. cucumeris on O. albidipennis is presumably of negligible importance. Orius albidipennis preyed uponmite eggs and adults in the absence of Thrips tabaci (Lindeman) (Thysanoptera: Thripidae), but in its presence predation on mite eggs was abandoned and predation on adult mites unchanged (sweet pepper) or reduced (eggplant, cucumber). The IGP-level of O. albidipennis on N. cucumeris was highest on sweet pepper and lowest on cucumber. Inclusion of host plant aspects in evaluations of the IGPpotential between predators intended for simultaneous applications for biocontrol is thus of importance.
