Abstract

Morphological anomalies in the ontogenesis of potato ladybug Henosepilachna vigintioctomaculata (Motschulsky, 1857) (Coleoptera: Coccinellidae). N.V. MATSISHINA, P.V. FISENKO, O.A. SOBKO (Federal Scientific Center of Agrobiotechnology in the Far East named after A.К. Chaika, Ussuriysk, Timiryazevsky village).

The morphological characters of insects are defined by both external and genetic factors. The external factors (mechanical, thermal, chemical, radiation), especially when deviating from the average values, often cause insect morphology violations. To date, there is no generally accepted terminology for several morphological anomalies caused by exogenous factors. The morphological anomalies of Henosepilachna vigintioctomaculata in the ontogenesis are given for the first time. The occurrence frequencies and the complexity of the detected anomalies are determined, and assumptions about the mechanisms and causes of their occurrence are made.
