摘  要:
在25℃恒温、RH90%的条件下,对萧氏松茎象成虫在湿地松、火炬松、马尾松、黑松、雪松、杉木、金钱松和罗汉松共8种植物上取食、繁殖及生活历期进行了研究。结果表明:成虫取食湿地松的量最大,为83.9 mm2.头-1.d-1,其次是马尾松、黑松和火炬松;取食金钱松和罗汉松的量最小。成虫取食湿地松的产卵期最长,为57.4天;产卵量最大,平均为14.3粒,取食马尾松、黑松和火炬松的次之。取食马尾松、湿地松、火炬松、黑松和雪松产的卵孵化率均在80%以上;取食杉木的最小,为50%,取食金钱松和罗汉松的雌虫不产卵。取食湿地松、火炬松和马尾松的成虫历期较长,取食杉木、罗汉松和金钱松的历期较短。

摘  要:
Effects of 8 plant species on the feeding,fecundity and duration of Hylobitelus xiaoi adults were evaluated at a constant temperature of 25 ℃ and relative humidities(RH) of 90%.Results showed that the adults consumed 83.9 mm2 of Pinus elliottii twigs which was significantly higher than they did on other plant species.Adults laid significantly more eggs and lived significantly longer on Pinus elliottii twigs than on the other plant species twigs.Feeding on Cunninghamia lanceolata、Podocarpus macrophyllus and Pseudolarix kaemoferi led to higher mortality of the adults.
