Abstract : the biological control effect on fruit tree insects and eco - economic benefit of interplanting mentha spicata with orchard was studied and analysed based on field polt experiment. the result shows : interplanting mentha spicata with orchard have obviously biological control effect on fruit tree insects like phyuoenistis eitrella stainton, papilio xuthus l, phyllocoptruta oleivora ashmead and myzus perieas sulzer ect, interphanting mentha spicata with slope orchard could reduce soil and water losses, and improve soil physical - chemistry property effectively, its also accelerate fruit tree growth and increase the yield of fruit tree, and has good economic benefit
文摘:在野外小區試驗的基礎上，對果園套種留蘭香生物防治果樹蟲害的作用及其生態經濟效益進行了研究和分析，結果表明：果園套種留蘭香對潛葉蛾、柑橘鳳蝶和桃蚜等果樹害蟲有明顯的生物防治效果；在坡地果園套種留蘭香能有效減輕水土流失、改善土壤的理化性狀，促使果樹的生長和提高果樹的產量，並具有良好的經濟效益In this paper two - generation reproduction toxicity of fenvalerate, a - cypermethrin, chlorpyrifos, and triazophos was tested in a 21d period with water flea, daphnia magna, . the toxicity indicator included longevity, body length, days to first brood, days to first pregnancy, number of youth per female, intrinsic rate of natural increase ( r ), and number of broods per female. accordingly, the dose - response relations and relations between the chronic responses and enzyme levels were investigated
為了確定水蚤體內生化指標與慢性毒害效應之間的關系，特別是在低濃度暴露狀態下生化指標改變的生物學意義，以便能更準確預測早期農藥對水蚤種群的潛在危害，本文以浙江省常用殺蟲劑氰戊菊酯、高效氯氰菊酯、三唑磷和毒死蜱進行了大型蚤（ d . magna ）的急性和慢性毒性試驗（包括子代水蚤的恢復試驗） 。They could damage crops and make them vulnerable to infection and infestations by pests and weeds, thereby reducing food supplies and potentially contributing to malnutrition
它們會損害莊稼，使莊稼易受害蟲和雜草的影響和侵襲，因此引起食物供應不足和潛在的營養不良。Pests, their potential risks should not be overlooked
除害劑雖然能有效地控制蟲害，但其潛在危害則不容忽視The advantages of plantain at high population density include potential to increase yields significantly, better crop cycle planning to harvest during best market conditions, optimum use of land because one hectare of high density plantain can produce as much as 3 - 5 hectares of conventional planting, high production of good quality corms used as seed for the next cycle and intensive management resulting in a lower incidence of pests, diseases and weeds
大蕉密植的優勢在於：有顯著的增產潛力，有較好的生產周期以適應最佳市場條件，能高效利用土地（密植1公頃相當于通常的3 ~ 5公頃） ，可生產出可作為下季種子的大量優質球莖，集約管理可減少病、蟲、草害的發生。Environmental monitoring is another potentially large area for using immunoassays including detection of noxious substances such as pesticides, insecticides, and bacteria in drinking water
環境監控也是另一個潛在的需要免疫檢測的大領域，包括檢測有害物質如殺蟲劑和飲水中的細菌。It cooperates with ptth to regulate and control ecsysteroidogenesis on pg of insect. so it is a potential pest control agent
它與ptth共同調控和控制蛻皮激素的合成，因此具有潛在的害蟲控制的可能。Chemical, physical or biological contaminants that have or may have or have potential hazardous effect on human health, including pathogens, pests, pesticide and drug residues, heavy metal residues, toxins, and animal - derived food products non - compliant with labeling requirements, etc
存在或可能存在風險及存在潛在危害的具有化學、物理、生物性污染，這些污染包括病原微生物、病蟲害、農獸殘、重金屬殘留、毒素等，以及不符合標簽規定的進出口動物源性食品等。Methods of test for cereals and pulses - determination of hidden insect infestation
