摘要
为深入理解水分在昆虫趋泥行为中的作用,测定了在一天中林间温湿度的变化情况,分析了环境温湿度对黄脊竹蝗Ceracris kiangsu体内含水率及趋尿行为的影响。结果表明:雌、雄虫体内在一天内含水率的变化情况基本一致,呈现"W"型的变化趋势,与环境温度呈负相关(r=-0.85,P=0.079),与湿度无相关关系(r=-0.43,P=0.779);在中午高温低湿时段(12:00-14:00),黄脊竹蝗对人尿的访问量最大,达到(428.00±44.24)次,(140.00±20.64)头,且黄脊竹蝗成虫首次访问诱饵的时间也最短,仅为(410.8±52.6)s。林间诱杀结果与行为观测基本一致,中午高温时段诱杀量最大,达到(140.00±20.64)头。不同时段诱集的成虫性比结果表明:发生趋尿行为的黄脊竹蝗雌虫比例显著高于雄虫(P<0.01)。环境温湿度对黄脊竹蝗的趋尿行为影响显著,利用毒饵诱杀技术进行黄脊竹蝗防控时,选择在炎热干燥的气候条件及环境条件下实施更为有效。
To better understand the role of water uptake in the urine-puddling behavior of an important bamboo pest, Ceracris kiangsu(Orthoptera: Oedipodidae), the yellow-spined bamboo locust, in southern China, ambient temperature and humidity at different times of the day were examined and analyzed for their effects on water content of the body in adults and on the urine-puddling behavior. Puddling behavior of the yellow-spined bamboo locust was observed with a camera recording system, and C. kiangsu adults were trapped by toxic bais with human urine fermented for 30 d mixed with 18% bisultap in bamboo forest. Simultaneously, ambient temperature and humidity were monitored at the same experimental sites in Hunan province. Results showed that the change of water content in the body for females and males was similar, and was influenced obviously by ambient temperature and humidity. Observations showed that the most visits [(428.00 ± 44.24) bouts] over a whole day were observed from 12:30-14:00 with onset time of the first visit to the bait being the shortest [(410.8 ±52.6) s]. Trap experiments showed that 140.00 ± 20.64 were killed from 12:30-14:00, more than any other period(One-way ANOVA analysis, P〈0.05). Also the sex-ratio of adults trapped by the bait indicated that the urine-puddling behavior mainly occurred with female C. kiangsu adults(t test, P〈0.05). Implications were that ambient temperature and humidity strongly affected the urine-puddling behavior of C. kiangsu adults, and the methods of trapping adults with toxic bait were effective in a hot and dry weather.
