摘要: 【目的】 研究玉米螟发生与作物布局间的关系,为玉米螟的生态防控提供理论依据。【方法】 在新疆喀什地区疏勒县玉米螟典型发生区,用诱蛾量、落卵量、幼虫量、蛹量以及玉米蛀秆率、玉米茎秆和果穗蛀孔数、活虫数等指标,依次评估玉米+棉花(Tr1)、玉米+甜瓜(Tr2)、玉米+小麦(Tr3)邻作模式下玉米螟种群动态与危害。【结果】 不同邻作模式下诱捕器诱蛾量、落卵量、幼虫量、蛹量有一定的差异(P < 0.005);其中,Tr1邻作田诱蛾量(越冬代、1代和2代)、落卵量、幼虫量和蛹量显著高于Tr2和Tr3邻作田(P < 0.005),Tr2邻作田的诱蛾量、落卵量、幼虫量和蛹量高于Tr3邻作田但差异不显著(P > 0.005);不同邻作模式下玉米螟发生与危害有一定的差异(P < 0.005);Tr1、Tr2、Tr3 3种不同邻作模式下玉米螟蛀秆率均值为18.03%且差异显著(P < 0.005),总蛀孔数、总活虫数由大到小排序依次为Tr1>Tr3>Tr2、Tr1>Tr2>Tr3。【结论】 玉米螟越冬代成虫羽化后更偏好于向玉米+棉花(Tr1)邻作田迁移且1 代和2代成虫以及棉花周围有种植玉米的田,通过作物布局和合理的药剂防治调控玉米螟种群发生与危害。

Abstract: 【Objective】 Ostrinia furnacalis is the main pest on corn. The relationship between Ostrinia furnacalis occurrence and crop distribution was studied in the hope of providing a theoretical basis for ecological prevention and control of the pest.【Methods】 In the typical occurrence area of Ostrinia furnacalis in Shule County, the effect of crop distribution experiment was conducted in which the amount of moth, eggs dropping amount, larvae, alfalfa and the index of decay rate of stem, the number of holes on stalks and cluster and living insects were used to evaluate the population dynamics and damage of Ostrinia furnacalis under maize+cotton (Tr1), maize+melon (Tr2) and maize+wheat (Tr3) intercrop patterns.【Results】In terms of population dynamics, there were some differences in the amount of trapped moths, dropped eggs, larvae and alfalfa under different crop distribution (P < 0.005). The amount of moth (overwintering, 1st and 2nd generations), eggs, larvae and alfalfa of Tr1 adjacent field were significantly higher than those of Tr2 and Tr3 (P < 0.005); Moreover, the amount of dropped moths, dropped eggs, larvae and alfalfa in the Tr2 adjacent field were higher than those in the Tr3, while the difference was not significant (P > 0.005); In terms of hazard: There were some differences in the occurrence and damage of Ostrinia furnacalis (P < 0.005) under different crop distribution; In addition, the average rate of corn stalk rate was 18.03% and the difference was significant (P < 0.005), and the total number of holes and living insects from large to small was Tr1>Tr3>Tr2 and Tr1>Tr2>Tr3. 【Conclusion】 After emergence of overwinting adults of the Ostrinia furnacalis, they preferred to migrate to the Tr1 neighboring field and the 1st and 2nd generation adults preferred the field of corn planting around the cotton. Above all, occurrence and damage of the Ostrinia furnacalis could be regulated by crop distribution and rational chemical control.
