摘要：

The longevity and fecundity of inseminated and uninseminated females of four phytophagous mite species from the Indo-Pacific tropical area, Tetranychus fijiensis, T. lambi, T. marianae and T. neocaledonicus, were investigated. Uninseminated females of these species laid fewer eggs but lived longer than inseminated ones. The 50% survival rate of inseminated females was attained 20, 15.5, 14.5 and 13.5 days before that of uninseminated females in T. marianae, T. neocaledonicus, T. fijiensis and T. lambi respectively. Comparison between the egg production of inseminated and uninseminated females shows that the fecundity of inseminated females was roughly twice as great in T. marianae and T. fijiensis, 1.5 times as great in T. neocaledonicus and 1.25 times as great in T. lambi. The range of differences observed between species may perhaps result from adaptation to the climate of their area of origin.
