[Kin selection and developmental rate of malarial mosquitoes with different karyotypes]

Changes in the adaptive value of genotypes through the course of relationships within and between malaria mosquito families at larval stages were studied in Anopheles messeae, the species with chromosome polymorphism. It was shown that interactions between sibs can affect their viability and developmental rate. Larvae with "northern" inversions (r-strategists) developed significantly slower when kept together with larvae carrying the "southern" chromosome variants (K-strategists). A decrease in relative fitness was observed in larvae with the northern inversion XL1, which were kept on an insufficient diet. The relationship between kin selection and the formation of adaptive strategies in A. messeae are discussed.
