4种昆虫生长调节剂（IGRs） BAY SIR 8514[1-4-三氟甲氧基苯- 3-（2-氯苯甲酰）尿素]、二氟苯脲、甲基丁烯和uv -678[2-甲氧基9-（对异丙基苯）-2,6-二甲基壬烷]以5ppm的浓度施用于小麦面粉或谷物，对苏里南稻瘟菌（L.）、castaneum （Herbst）、Rhyzopertha dominica （F.）和米象（L.）进行了抗性评价。BAY SIR 8514和二氟苯脲对苏里南稻蛾、castaneum和多米尼加稻蛾的卵和幼幼虫均有较强的杀卵活性，除对苏里南稻蛾和多米尼加稻蛾有杀卵作用外，对三种稻蛾的成年幼虫均有较高的死亡率。BAY SIR 8514和甲基戊二烯也影响了预暴露于igr处理食物2周的亲本成虫的后代产量。MV-678似乎是测试中活性最低的化合物。
Four insect growth regulators (IGRs), BAY SIR 8514 [1-4-trifluoromethoxyphenyl)- 3-(2-chlorobenzoyl) urea], diflubenzuron, methoprene, and MV-678 [2-methoxy 9-( p isopropylphenyl)-2,6-dimethylnonane], applied at 5 ppm to wheat flour or grain, were evaluated against Oryzaephilus surinamensis (L.), Tribolium castaneum (Herbst), Rhyzopertha dominica (F.), and Sitophilus oryzae (L.). BAY SIR 8514 and diflubenzuron zuron were highly active against the eggs and younger larvae of O. surinamensis, T. castaneum , and R. dominica Methoprene, besides its ovicidal action against O. surinamensis and R. dominica , caused substantial mortality in the full-grown larvae of the three species. BAY SIR 8514 and methoprene also affected the subsequent progeny production of parent adults preexposed to IGR-treated food for 2 weeks. MV-678 appeared to be the least active compound tested.
Diflubenzuron and methoprene had no adverse effects on the development of S. oryzae inside grain kernels infested with parent adults 1 day after grain was treated. However, in grain treated with BAY SIR 8514, diflubenzuron, and methoprene and infested with this insect after 12 months of posttreatment storage, the development of this species was arrested significantly. BAY SIR 8514 and diflubenzuron were more active against the eggs and younger larvae, with methoprene showing activity against all stages from egg to preemergence adults of this species. In testing IGRs against internal feeders, it is important to allow for penetration of the active ingredients into the inner portions of grain kernels before assessing effects.
