Abstract

With the rise of insecticide resistance in common stored product insect species and fewer options for control due to increased regulatory oversight, it is imperative to explore other options for management. One option is the use of inert dusts such as diatomaceous earth (DE) or amorphous silica dust. In this study, we investigated the utility of an amorphous silica dust originally formulated for use against bed bugs, but applied here as a grain protectant for two stored products insects (Sitophilus granarius and Rhyzopertha doninica). A total of 200 g of wheat was conditioned with five concentrations of silica dust (ChinCheX Bed Bug Insecticide, 99 % amorphous silica), including: 0 (control), 100, 200, 500, and 1000 ppm. Insects were exposed continuously with condition evaluations at 7 and 14 days. Adults were then removed and the grain was kept for 65 d to assess progeny production. Mortality was 90 and 100 % for the 500 and 1000 ppm treatments for R. dominica and 100 % for both 500 and 1000 ppm treatments for S. granarius. Progeny production was less than 2 insects at 200 ppm and zero at 500 and 1000 ppm for R. dominica, while for S. granarius, there was less than 1 insect at 500 ppm and zero at 1000 ppm. Overall, we found that silica dust is an effective grain protectant on wheat against these bulk storage pests and provides a valuable option for use in an integrated pest management program.

无定形二氧化硅粉作为谷物保护剂防治粟象和粟纹蝇的效果研究
随着普通储藏产品昆虫对杀虫剂耐药性的上升,以及由于监管监督的加强,控制的选择越来越少,探索其他管理选择势在必行。一种选择是使用惰性粉尘,如硅藻土(DE)或无定形二氧化硅粉尘。在这项研究中,我们研究了一种无定形二氧化硅粉尘的效用,这种粉尘最初是用来对付臭虫的,但在这里被用作两种储存产品昆虫(谷物象和灰鼠)的谷物保护剂。用五种浓度的二氧化硅粉尘(ChinCheX臭虫杀虫剂,99%无定形二氧化硅)对200 g小麦进行处理,包括:0(对照),100,200,500和1000 ppm。连续暴露7 d和14 d进行状态评价。然后去除成虫,保存65 d,以评估后代的产量。500 ppm和1000 ppm处理的多米尼加赤霉病死亡率分别为90%和100%,500 ppm和1000 ppm处理的谷物赤霉病死亡率均为100%。在200 ppm和500、1000 ppm条件下,多米尼加赤霉病虫的子代产量小于2只,而在500 ppm和1000 ppm条件下,赤霉病虫的子代产量小于1只,而在1000 ppm条件下,赤霉病虫的子代产量为0。总的来说,我们发现二氧化硅粉尘是一种有效的谷物保护剂,对小麦抵抗这些散装储存害虫,并提供了一个有价值的选择,用于害虫综合管理计划。

期刊介绍: The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
