摘 要:研究了9個梯度變溫對濕地松粉蚧Oracell aacuta(Lobdell)越冬代成蟲和第一代卵的影響,結果表明:濕地松粉蚧雌成蟲存活率隨溫度升高逐漸下降,高溫對成蟲產卵有一定抑制作用,持續(xù)較高溫度處理成蟲,其產卵量顯著降低;濕地松粉蚧成蟲生長發(fā)育的最適溫度為27~21℃,卵的孵化和發(fā)育的最適變溫組合是29~23℃;在29~23℃以上的溫度波動對卵的發(fā)育速率有增速作用,而在29~23℃以下的溫度波動對卵的發(fā)育速率則有減速作用.
關鍵詞:濕地松粉蚧;變溫;存活率;產卵量;發(fā)育速率

AbstractThe development, survival and reproduction of the overwintering females of Oracella acuta and their eggs were observed under various alternate temperatures in this paper. The results indicated (1) the higher the alternate temperature was, the lower the survival rate was. And the number of eggs laid by per female had the same trend but in a less extents, (2) The female cannot survived in a long periods of high temperature(under 3529), 3The alternate temperature(2721) was considered as the best temperature based on the development rate and the survival rate of the adults; (4) The alternate temperature(2923) was considered as the best temperature based on the development rate and the survival rate of the eggs; (5) The alternation in a low temperature range(below the alternate temperature 2923) could slow down the development rate of eggs. However the alternation in a high temperature (above the alternate temperature 2923) range could accelerate the development rate of eggs.
