aacuta(Lobdell)越冬代成蟲(chóng)和第一代卵的影響，結(jié)果表明：濕地松粉蚧雌成蟲(chóng)存活率隨溫度升高逐漸下降，高溫對(duì)成蟲(chóng)產(chǎn)卵有一定抑制作用，持續(xù)較高溫度處理成蟲(chóng)，其產(chǎn)卵量顯著降低；濕地松粉蚧成蟲(chóng)生長(zhǎng)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(dòng)對(duì)卵的發(fā)育速率有增速作用，而在29～23℃以下的溫度波動(dòng)對(duì)卵的發(fā)育速率則有減速作用. Effect of Alternate Temperatures on the Experimental Population of Oracella acuta TANG Cai（Laboratory of Insect Ecology,
South China Agric. Univ.，Guangzhou 510642， China） Abstract：The 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 35～29℃), （3）
The alternate
temperature(27～21℃) was
considered as the best temperature based on the development rate and the
survival rate of the adults; (4) The alternate temperature(29～23℃) 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
29～23℃) could slow down the
development rate of eggs. However the alternation in a high temperature (above
the alternate temperature 29～23℃) range could accelerate the development rate of
eggs. |
