Особенности проявления инвазионной активности энтомопатогенных нематод (Nematoda: Steinernematidae) в зависимости от биотических и абиотических факторов окружающей среды

Abstract

A comparative assessment of the features of invasive activity of two species of nematodes of the family Steinernematidae is provided, based on a mathematical modeling of dependence of intensity of invasive activity and mortality of insects on the host environment exposure (low dose exposure, duration of the period of free contact). Nematode Steinernema feltiae protense provide a higher mortality rate over a wide temperature range (6 to 28 °C), whereas Steinernema carpocapsae strain “agriotos” range is 20 to 28 °C. S. feltiae protense demonstrates more prospects for the use as a biological agent than S. carpocapsae.
