    摘要:

    【目的】研究锈赤扁谷盗Cryptolestes ferrugineus成虫、土耳其扁谷盗Cryptolestes turcicus和长角扁谷盗Cryptolestes pusillus雌成虫对不同波长光的趋性。【方法】室内应用光行为反应装置测试3种扁谷盗羽化1、11、21和31日龄(雌)成虫对试验波长303、320、330、340、351、368、400、445、460、480、520、525、545、560、575和580 nm的趋光率。【结果】 锈赤扁谷盗羽化1、11、21和31日龄成虫趋光率最高的刺激光波长分别为351、351、400、480 nm,对锈赤扁谷盗成虫诱集效果较好的光波长有351、400和445 nm,随着日龄的增加,对锈赤扁谷盗成虫诱集率大于20%的光波数增加;土耳其扁谷盗羽化1、11、21和31日龄趋光率分别为16%~51%、11%~46%、7%~37%和4%~28%,雌成虫趋光率最高的刺激光波长分别为351(368)、368、330和351 nm,对土耳其扁谷盗雌成虫诱集效果较好的光波长有368、351和303 nm;长角扁谷盗羽化1、11、21和31日龄趋光率分别为1.11%~75.56%、18.89%~70.00%、33.33%~62.22%和22.22%~71.11%,雌成虫趋光率最高的刺激光波长分别为575、320、400(445)和320(560)nm,对长角扁谷盗雌成虫诱集效果较好的光波长有320、575和330 nm。【结论】锈赤扁谷盗成虫的趋光性随着日龄的增加而增强,土耳其扁谷盗雌成虫的趋光性随着日龄的增加而下降,长角扁谷盗雌成虫的趋光性随着日龄的增加略为下降。

    Abstract:

    【Objective】 To study phototaxis of Cryptolestes ferrugineus adults, the female adults of Cryptolestes turcicus and Cryptolestes pusillus to lights with different wavelengths【Method】 A light behavior reaction device was used to test the phototactic ratios of 1-day-old, 11-day-old, 21-day-old and 31-day-old (female) adults of three species of Cryptolestes to lights with wavelengths of 303,320,330,340,351,368,400,445,460,480,520,525,545,560,575 and 580 nm.【Result】The wavelengths of simulating lights resulting in the highest phototactic ratios of the 1-, 11-, 21-, and 31-day-old adults of C. ferrugineus were 351, 351, 400, and 480 nm respectively. The wavelengths with relatively better trapping effects for C. ferrugineus adults were 351, 400 and 445 nm. With the increase of age, the number of wavelengths that led to over 20% phototactic ratio of C. ferrugineus increased. The phototactic ratios of 1-, 11-, 21-, and 31-day-old female adults of C. turcicus ranged from 16% to 51%, 11% to 46%, 7% to 37%, and 4% to 28% respectively, and the light wavelengths resulting in the highest phototactic ratios were 351(368), 368, 330, and 351 nm respectively. The wavelengths with relatively better trapping effects for female adults of C. turcicus were 368, 351 and 303 nm. The phototactic ratios of 1-, 11-, 21-, and 31-day-old female adults of C. pusillus ranged from 51.11% to 75.56%, 18.89% to 70.00%, 33.33% to 62.22%, and 22.22% to 71.11% respectively, and the light wavelengths resulting in the highest phototactic ratios at these four ages were 575, 320, 400(445), and 320(560) nm respecticely. The wavelengths with relatively better trapping effects for female adults of C. pusillus were 320, 575 and 330 nm. 【Conclusion】The phototactic ratios of C. ferrugineus adults increase with age, the phototactic ratios of the female adults of C. turcicus decrease with age, and the phototactic ratios of the female adults of C. pusillus decreases slightly with age.
