[Inversion polymorphism of the malaria mosquito Anopheles messeae. IX. Cannibalism in larvae as a selection factor].

The genetic consequences of larval cannibalism were studied in mosquito Anopheles messeae Fall. (Diptera. Culicidae) with "south" inversional combinations. It is shown that mosquito with karyotypes XL11(2)R00(3)R00(01, 11) eat the larvae of the species named more actively than mosquito with karyotypes XL00(01)2R00(3)R00(01)3L00(01, 11). Evidently, adaptation of mosquito with "south" genocomplexes was developed in two directions: 1) more effective utilization of food resources in the larvae with the inversion XL0 which are wide-spread at south-west of the species areal; 2) the spread of cannibalism in the larvae of eldest ages with the XL1 inversion which inhabited south-east of the species areal.
