Abstract

BACKGROUND

Insect growth regulators are promising alternatives to traditional pesticides in stored grain. The efficacy of the juvenile hormone analogue methoprene was evaluated as a layer treatment in a laboratory experiment for control of Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae) in wheat, rice and maize.

RESULTS

Adults of R. dominica were placed in vials containing 33, 26 and 29 g (to a depth of 6.5 cm) of wheat, rice and maize, respectively, that was entirely or partially treated with 1, 5 or 10 mg kg(-1) methoprene. In wheat and rice, the layer treatments were not as effective as the whole-grain treatment, but there was decreased progeny production as the application rate increased. However, on maize the partial treatments were as effective as the whole-grain treatment at 5 and 10 mg kg(-1) .

CONCLUSIONS

The results suggest that partial layer treatments with methoprene can be used to control R. dominica on maize but may not be effective for control of this species on wheat and rice.

摘要

背景

昆虫生长调节剂是传统储粮杀虫剂的替代品。在实验室条件下，评估了保幼激素类似物双氧威作为一种粮面施药处理药剂对玉米象（鞘翅目：象甲科）的防治效果，供试储粮为小麦、稻谷和玉米。

结果

将玉米象成虫置于盛有 33、26 和 29 克（深度为 6.5 厘米）小麦、稻谷和玉米的小瓶中，这些粮食或全部、或部分用 1、5 或 10 毫克/千克双氧威进行了处理。在小麦和稻谷中，粮面施药处理的效果不如全粮处理，但随着施药率的增加，后代的繁殖量减少。然而，在玉米上，局部施药处理在 5 和 10 毫克/千克的浓度下与全粮处理的效果相同。
