Data from: Evaluating the Long-Term Efficacy of Four Active Ingredients against <i>Rhyzopertha dominica </i>(F.) (Coleoptera: Bostrichidae) and <i>Sitophilus oryzae </i>(L.) (Coleoptera: Curculionidae) on Stored Sorghum

The objective of this study was to determine the residual efficacy of four commercially available grain protectants, Gravista® (deltamethrin + methoprene + PBO), Diacon® IGR (methoprene), Sensat™ (spinosad), and EverGreen® (pyrethrin), applied to sorghum and held for each of eight storage periods spanning 28 weeks, against Rhyzopertha dominica and Sitophilus oryzae. Subsamples were collected every 4 weeks (up to 28 post grain protectant application) and infested with 10 adults of either R. dominica or S. oryzae. The initial adult mortality was assessed 7 d post-exposure to the treated grain. After adult mortality was determined, the sorghum was held for 8 weeks and adult progeny were counted. Additionally the amount of frass and insect damaged kernels were also evaluated.本研究旨在明确4种市售谷物保护剂——Gravista®（溴氰菊酯+烯虫酯+PBO）、Diacon® IGR（烯虫酯）、Sensat™（多杀菌素）及EverGreen®（除虫菊素）——施用于高粱后，在横跨28周的8个储藏周期下对谷蠹（Rhyzopertha dominica）与米象（Sitophilus oryzae）的残留持效防治效果。每4周采集一次子样本（直至施药后28周），每份子样本均接入10头谷蠹或米象成虫。将成虫暴露于处理后的谷物7天后，评估初始成虫死亡率。完成成虫死亡率测定后，将该处理谷物继续储藏8周，随后统计子代成虫数量。此外，本研究还对虫粪量与虫害籽粒数进行了评估。
