Abstract

Aphids, particularly Aphis gossypii Glov., is one of the most-important-pests in squash farms, caused serious losses by sucking plant sap in addition to plant viruses' transmission such as Papaya ringspot virus-W (PRSV-W). The current work conducted to study of the effect of various-systemic-insecticides and mineral-oil against melon-aphid, “ Aphis gossypii ” and its ability on transmissions of non-persistent-viruses under laboratory conditions. Data obtained showed that the “flonicamid” and “pymetrozine” recorded significantly-reduction in virus-acquisition and inoculations when compared-with control “also” reductions were compared-with mineral-oil applications. On-other-hand, data obtained of insecticide-residues activity and KZ-oil on “PRSV” transmission-rate by “ A. gossypii” revealed that flonicamid had significantly higher persistence up to 12 days followed by pymetrozine. The mineral oil experienced a significant increase in transmission rate as its efficacy decreased dramatically on the eighth transmission and twelfth days.

某些杀虫剂和KZ油对“棉蚜”存活及番木瓜环斑病毒“Prsv”传播能力的影响

蚜虫，尤指棉蚜。番木瓜环斑病毒(PRSV-W)等植物病毒的传播，以及番木瓜环斑病毒(PRSV-W)等植物病毒的传播，都是番瓜养殖场中最重要的害虫之一。目前的工作是在实验室条件下研究各种系统杀虫剂和矿物油对瓜蚜(棉蚜)的影响及其对非持续性病毒传播的能力。获得的数据表明，与对照组相比，“氟硝胺”和“吡蚜酮”的病毒获取和接种量显著减少，“也”与矿物油应用相比减少。另一方面，杀虫剂残留活性和KZ-oil对棉蚜传播“PRSV”率的影响数据显示，氟硝胺的持久性显著高于棉蚜酮(12 d)，其次是吡虫胺(12 d)。矿物油在第8天和第12天的传播率显著增加，其效果显著下降。
