| Abstract | An estimate of the inbreeding coefficient, FIS, of the coffee berry borer, Hypotkerzemus kainpei Ferrari, was calculated from genotype frequencies of endosulfan resistance in beetles collected from berries in 41 different fields on the East Coast of New-Caledonia. Two different estimates were obtained as a function Gf sampling date: Fls=0.491 & 0.059 (s.e.) for samples collected innSeptember, and F,s=0.215 10.108 for samples collected in April. These values of FIS are very high in comparison to those of most insects, but surprisingly low given current understandings of H. kanzpei mating pattems. The difference between April and September FIS estimates is discussed in terms of insecticide regimes and seasonal __-va;iability of sib inbreeding levels. The high level of inbreeding in the coffee berry borer increases frequencies of homozygotes relative to heterozygotes. Inbreeding will accelerate resistance evolution whenever the fitness-of homozygous resistant _ I |
