摘要
研究了桃蚜、松毛虫赤眼蜂两种昆虫发育快慢、出生先后与其它几项特征之间的关系。结果表明,同时出生的一批个体,虽在几乎一致的生境中,发育快慢也不一,而发育快慢不一又与其个体大小、生植力等特征呈正相关;同一母体的后代,出生先后不一,其个体大小、发育速率、生殖力等特征可有显著差异。
The relationships between developmental velocity, birth sequence and its biological cha-racteristics in Myzus persicac (Sulzer) and Trichogramma dendrolimi Mat sumura were investigatcd.The results revealled that (1)individuals of a cobort born at the same time, in spite of being offerednearly identical rearing conditions, showed significant variations in development velocity, and develo-pment velocity was positively correlated with body size and fecundity, and (2) offspring of the samefemale. born at different positions along the birth sequence, sbowed significallt variations in body si-ze, development velocity and fecundity.
