| 摘 要： | 目的]为明确油松毛虫在油松上的产卵和取食部位以及可能机理,为未来害虫发生预测模拟提供基础信息数据。方法]通过室内模拟试验,统计油松毛虫在盆栽油松幼苗不同部位上的产卵量和取食不同油松针叶的偏嗜情况及死亡率;测定油松针叶内含物含量并与油松毛虫偏嗜行为进行了相关性分析。结果]在一年生油松针叶上平均产卵块数最多(3.10±0.28),显著高于二年生针叶和三年生针叶;取食一年生油松针叶的油松毛虫数量最多(13.40±0.91)、死亡率最低(13.60%±4.87%),显著优于取食二年生油松针叶和三年生油松针叶的幼虫。油松毛虫幼虫取食选择、成虫产卵选择和幼虫体长与油松针叶内含水量成显著正相关(P0.01);与寄主总酚含量(P0.01)和碳氮比(P0.05)成显著负相关。结论]油松毛虫对一年生油松针叶具有明显的产卵和取食偏嗜行为。一年生油松针叶内含水量最高、总酚含量最低、有机碳含量最低可能是造成寄主偏嗜行为的原因。

| Abstract: | Objective] The aim of this study was to know the different preferences on different parts of Chinese pine by the pine caterpillar and the possible mechanisms which provides the basis information data for the future pest forecast simulation. Methods] According to the indoor simulated experiments, the author analyzed the amount of egg mass laid on different types of pine needles by the pine caterpillar adult, the feeding preference and death rate of larvae feeding on different types of pine needles. We tested the content of inclusions in pine needles and analyzed the relationship between the preference and the content of pine needles. Results] The results showed that the number of egg mass laid on One-year-old pine needles was 3.10±0.28 which was significantly higher than Two-years-old pine needles and Three-years-old pine needles. The amount of larvae feeding on one-year-old pine needles was the biggest (13.40±0.91) and the death rate was the lowest (13.60%±4.87%), which were significantly better than feeding on Two-years-old pine needles and three-years-old pine needles. The paper results indicated that the pine caterpillar had feeding and oviposition preferences. The preference behaviors were significant positive correlation on water content (P<0.01), and negative correlation on the contents of total phenol (P<0.01) and C/N (P<0.05) of these three kinds of pine needles. Conclusion] The pine caterpillar preferred to feed and oviposition on one-year-old pine needles. The reason of the preference behaviors maybe was the higher water content, the lower total phenol and carbon content of One-year-old pine needles. |
