研究了越冬代尖钩宽黾蝽成虫的耐饥力大小 .结果表明 ,在 14~ 3 2℃范围内 ,尖钩宽黾蝽不同翅型雌、雄成虫的耐饥力随温度升高而下降 ,各温度间差异显著 .14℃时 ,尖钩宽黾蝽成虫的耐饥时间最长 ,达 3 2 10d(无翅型 )和 2 9 5 8d(有翅型 ) ,3 2℃时 ,则分别为 9 46d和 7 82d ;无翅型成虫耐饥力高于有翅型 ,同一翅型雌成虫的耐饥力又高于雄成虫 ,而且温度越低 ,二者间的差异越大 .不同密度下尖钩宽黾蝽成虫的耐饥力差异显著 ,1雌 1雄 /瓶的耐饥力显著高于 5雌 5雄 /瓶和 10雌 10雄 /瓶 ,而后二者间的差异则不明显 .另外 ,尖钩宽黾蝽 1龄若虫的耐饥力在各温度间的差异也显著 ,14℃和 2 0℃的耐饥力显著高于 2 6℃和 3 2℃ .
The results showed that the resistance to starvation of female and male adults with different winged finches decreased with increasing temperature in the range of 14 ~ 32 ℃ , And the difference was significant at each temperature.The adults had the longest hunger-resistance period at 312 ℃ (wingless type) and 295d (winged type) at 14 ℃, while at 32 ℃, Respectively, for 466 days and 7 82 days respectively. The resistance to starvation of the wingless adults was higher than that of the winged ones and that of the female adults with the same wings was higher than that of male adults, and the lower the temperature, the greater the difference between them The resistance to starvation of adults with sharp hookworm was significantly different. The resistance to starvation of 1 female and 1 male was significantly higher than that of 5 female and 5 male / female and 10 female and 10 male / female, respectively. However, the differences between the two groups were not significant. In addition, the hunger resistance of the first instar nymphs of Culter siberianus was also significantly different at all temperatures, and the hunger resistance at 14 ℃ and 20 ℃ was significantly higher than that at 26 ℃ and 32 ℃.
