Abstract:
Question: Can the sex ratio of the palm-seed borer beetle, Coccotrypes dactyliperda (Fabricus), be described by local mate competition? Does relatedness among neighbouring foundresses affect their offspring sex ratio in the context of local mate competition? Hypothesis: According to Hamilton's local mate competition hypothesis, the optimal sex ratio (proportion of males out of the total clutch) should increase as the number of foundresses increases. We predict that when multiple foundresses can assess their relatedness, relatedness among foundresses will decrease the sex ratio. Methods: We measured the effect of number of foundresses and relatedness among foundresses on offspring sex ratio in seven populations of C. dactyliperda in Israel. Results: In line with local mate competition theory, offspring of related foundresses had a lower sex ratio than offspring of unrelated foundresses and the sex ratio among offspring of a single foundress was lower than that of several unrelated foundresses. However, when the multiple foundresses were related, the offspring sex ratio of one and of several foundresses did not differ. This result may be explained by a high expectation of the related females that their sons will encounter only related males. © 2010 Daphna Gottlieb.
