不同引诱物及诱捕器对葡萄园白星花金龟诱集效果比较

【目的】白星花金龟Protaetia(Liocola) brevitarsis (Lewis)成虫是危害葡萄的重大害虫之一,研究不同果实和牛粪处理及诱捕器对葡萄园白星花金龟成虫的诱集效果。【方法】选用西瓜、番茄、蟠桃、甜瓜和苹果5种果实分别与牛粪组成诱集组合体,调查诱集效果和空白区、诱集区白星花金龟成虫在葡萄上的发生数量,采用四臂嗅觉仪进行白星花金龟成虫对果实和牛粪处理及单一牛粪处理趋性测定。分析桶状诱捕器、小蠹诱捕器和盆状诱捕器对白星花金龟成虫诱集效果。【结果】果实和牛粪处理均能减少白星花金龟成虫在葡萄上的危害。在不同处理中,西瓜和甜瓜处理成虫诱集量最多,均为43.50头,两处理间无显著差异,与其余处理间存在显著差异;果实和牛粪处理白星花金龟卵及幼虫总量比单一牛粪处理多;在各果实和牛粪处理中,番茄处理卵量最多,蟠桃处理幼虫数量最多;在白星花金龟成虫对果实和牛粪的趋性中,甜瓜和西瓜处理对雌虫吸引率较高,分别为43.33%、36.67%,两处理间无显著差异,选择系数分别为0.33、0.20,存在显著差异;甜瓜处理对雄虫吸引率最高,且选择系数最高,分别为33.33%和0.23,均与各处理间存在显著差异。在桶状诱捕器、小蠹虫诱捕器和水盆诱捕器中,无论是否投放白星花金龟诱芯,均为桶状诱捕器成虫诱集量最多,均与各诱捕器间存在显著差异。【结论】西瓜和甜瓜处理有较好的诱集效果;桶状诱捕器与白星花金龟诱芯的组合,可提高诱集效果。

Comparison of the Trapping Effect of Different Temptations Andtraps on Protaetia(Liocola) brevitarsis(Lewis) in Vineyard

【Objective】 The Protaetia brevitarsis Lewis adults is one of the major pests to grapes, so this project aims to investigate the luring effect of fruits combined with manure, and different traps to Protaetia brevitarsis Lewis adults in vineyard.【Method】 Different fruits such as watermelon, tomato, peach, melon and apple were selected to be combined with manure, and it was considered as a composite system to investigate the luring effect and the numbers of Protaetia brevitarsis Lewis adults on grapes in different treatments.Meanwhile, a four-arm olfactory was used to determine the tendency of Protaetia brevitarsis Lewis adults to the treatments of fruit-manure.The luring effects of different traps such as the barrel trap, a bookworm trap and the basin trap of Protaetia brevitarsis Lewis adults were investigated as well.【Result】 The treatments of fruit-manure could actually reduce the numbers of Protaetia brevitarsis Lewis adults on grapes and showed the better effect to adults.There was significant difference between the two treatments as well.The total number of eggs and larvae in treatments was more than single attractor; the largest number of eggs and larvae were observed in the treatments of tomato-manure and peach-manure, respectively; In the tendency determination of Protaetia brevitarsis Lewis adults, the treatments of melon-manure and watermelon-manure showed the better attraction to female with 43.33% and 36.67%, respectively.And there were no significant difference between the two treatments; However, the selection coefficients of two treatments were significantly different with 0.33 and 0.20, respectively.Regarding the attraction to male, both of the attractant percent and the selection coefficient of melon-manure were the highest in all treatments with 33.33% and 0.23, respectively.In the barrel trap, a bookworm trap and the basin trap, the total number of Protaetia brevitarsis Lewis adults captured by barrel trap was significantly higher than that of other traps whether or not the lure was put in.【Conclusion】 The treatments of fruit-manure showed better luring effect and reduce the numbers of Protaetia brevitarsis Lewis adults on grapes.The combination of barrel trap with P.brevitarsis lure can improve the trapping effect.
