An estimate of the inbreeding coefficient, Fis, of the coffee berry borer, #Hypothenemus hampei$ Ferrari, was calculated from genotype frequencies of endosulfan resistance in beetles collected from berries in 41 fields on the East Coast of New Caledonia. Two different estimates were obtained as a function of sampling date : Fis = 0,491 + ou - 0,059 (s.e.) for samples collected in September, and Fis = 0,215 + ou - 0,108 for samples collected in April. These values of Fis are very high in comparison to those of more insects, but surprisingly low given current understandings of #H. hampei$ mating patterns. The difference between April and September Fis estimates is discussed in terms of insecticide regimes and seasonal variability of sib inbreeding levels.... |
