The principle technological scheme of lepidopteroid rice pest and its natural
enemy management (PEM) on an ecosystem basis is elucidated. The elaborated
algorithm of rice agro-ecosystem management includes; (a) well grounded
economic thresholds (ET) both for rice leaffolder and yellow stem-borer; (b) monitoring
of number dynamics of lepidopteroid pests and their natural enemies; (c)
decision making with employment of the standard survey forms; (d) registration of
quantitative index – the zoophage efficiency level as an indicator of ecological resistance
of paddy agro-ecosystem on rice pest injury, and its usage for lepidopteriod
pest ET correction; (e) environment friendly tool set and tactics of lepidopteroid
pest population management.The tactics of PEM program implementation allows to
control of lepidopteroid pest populations (and secondary pests) and cutting down of
the quantity of chemical insecticide treatments six times under the condition of the
Red River Delta.
