我国仓储昆虫研究和防治的回顾与展望 总被引:15,自引:0,他引:15
与人类生活和经济发展密切相关的各类农产品,在其储藏期间和加工过程中常遭受仓储昆虫的严重为害。至今全世界已记载的仓储昆虫和螨类约500种,我国有383种,其中仓储昆虫242种,螨类141种。昆虫和螨类二者在储藏物中的栖境、食性和危害性基本相似,因此常通称为仓储害虫。它们多数潜藏在仓库、厂房、贷栈、商店、居室、图书馆、档案馆等处,为害储藏粮食、油料、动植物食品、中药材、烟草、棉、麻、丝、皮毛、呢料、图书、档案、纸质文物、竹木及其制品、电缆、塑料以及进出口贸易中的检疫商品等,造成很大损失。如粮油储藏期每年因虫害损… 相似文献

一种新杀虫剂对储粮害虫和作物害虫的杀虫效果 总被引:3,自引:1,他引:3
测定以植物提取物异硫氰酸酯为主要成分而复配的宏劲杀虫剂对玉米象Sitophilus zeamais(Motschulsky)、赤拟谷盗Tribolium castaneum(Herbst)和谷蠹Rhizopertha dominica(Fabricius)3种重要储粮害虫的熏蒸效果及其对菜青虫Pieris rapae(L.)、红蜘蛛Tetranychus cinnabarinus(Boisduval)的杀虫效果。结果表明,宏劲杀虫剂48h对玉米象、赤拟谷盗和谷蠹的LC50分别是0.016,0.009和0.009μL/mL,均明显低于常规熏蒸剂磷化铝的要求处理剂量;对菜青虫和红蜘蛛的LC50分别是0.0159和1.3738mg/mL,其防效均优于对照药剂3%阿菊乳油和3%新型水分散性颗粒剂。 相似文献

Abstract In Australia, canola is subject to attack by at least 30 species of invertebrate pests, although the composition of this pest complex can vary between regions. Mites (e.g. the redlegged earth mite Halotydeus destructor and the blue oat mites Penthaleus spp.), lucerne flea ( Sminthurus viridis ) and false wireworms (e.g. the grey false wireworm Isopteron punctatissimus and the bronzed field beetle Adelium brevicorne ) are the major pests threatening the seedling establishment, whereas aphids (the cabbage aphid Brevicoryne brassicae , the turnip aphid Lipaphis erysimi and the green peach aphid Myzus persicae ), the native budworm ( Helicoverpa punctigera ), the diamondback moth ( Plutella xylostella ) and the Rutherglen bug ( Nysius vinitor ) can cause irregular and unpredictable damage to the flowering and podding plants. Current tactics of pest management for canola rely largely on the use of synthetic pesticides, but this single-technology approach is likely to incur negative effects on natural enemies and the risk of pest resistance. Thus, the sustainable production of canola requires integrated pest management (IPM) strategies, in which cultural control, crop resistance and biological control are used as important components, with chemical inputs applied only when absolutely needed to restrict pests from reaching economically damaging densities. Such IPM strategies should be built around a fundamental understanding of pest ecology at both regional and local farm levels and the integration of renewable technologies. Therefore, future research efforts need to be focused on the canola-cropping system, with a particular emphasis on the impact of pest species, natural enemies of the pests, varietal resistance to pests and the spatial ecology of pest species. 相似文献

频振式杀虫灯在茶树害虫测报、防治中的应用 总被引:7,自引:0,他引:7
应用佳多频振式杀虫灯进行了茶树害虫的预测预报和防治试验。结果表明,该灯对茶园中的茶细蛾Caloptiliatheivora(walsingham)、茶毛虫EuproctispseudoconspersaStrand、斜纹夜蛾Prodenialitura(Fabricius)等茶树主要害虫有明显的诱集作用;同时,根据害虫成虫诱集时间、数量与面上生育期观察,其动态变化基本一致,可以用于幼虫的发生期、发生量预报,在面上应用频振式杀虫灯对3种的防治试验中取得明显的效果。认为该灯是一种安全、经济、有效、无污染的茶树害虫预测预报和防治工具。 相似文献

The sunn pests (Eurygaster spp.) which are important pests of wheat and barley, can lead to 100% yield loss in the case of an epidemic. This study was conducted to characterize the entomopathogenic fungi, obtained from the sunn pests collected from different overwintering areas of Turkey and determine their pathogenicity. Seventeen Beauveria pseudobassiana, 12 Beauveria bassiana, 16 Cordyceps farinosa, 1 Purpureocillium lilacinum, and 2 Clonostachys rosea species were identified. Pathogenicity tests were performed with three B. pseudobassiana, two B. bassiana, four C. farinosa, and one P. lilacinum isolates. B. pseudobassiana isolates BB34 and AF4 caused 100% death on the 9th day, and another B. pseudobassiana isolate E512 caused 100% death on the 12th day. C. farinosa isolate KOKA2 caused 95.8% death on the 15th day. Ultimately, B. pseudobassiana was determined to be the most prevalent and virulent species on sunn pests. 相似文献
