本试验以无纺布为载体面料,复合黄原胶为载体缓释调控剂,涂布天津科技大学筛选的3种粮食储存专用害虫驱避剂KDL02、KDL03和KDL06。再制成规格长250mm×宽180mm的新型粮食防虫袋,研究常见储粮害虫谷蠹、玉米象、杂拟谷盗的驱避效果。结果表明,最佳驱虫剂为KDL02,其最佳施药浓度为228μg/cm~2。平均驱避率为87.34%。
In this experiment, non-woven fabric as the carrier fabric, composite xanthan gum carrier as a sustained-release regulator, coated by the Tianjin University of Science and Technology screening of three kinds of grain storage pest repellent KDL02, KDL03 and KDL06. And then made a new type of food pest-proof bag with the specification of 250 mm in length and 180 mm in width, to study the repellent effect of the common stored grain pests, beet, corn and miscellaneous grains. The results showed that the best insect repellent KDL02, the best application concentration of 228μg / cm ~ 2. The average repellent rate was 87.34%.
