Ecological inefficiency of conventional IPM programs for apple orchard protection in the North Caucasus results from arbitrary use of compounds producing opposite ecological effects, i.e., broad-spectrum chemical insecticides after environment-friendly selective ones, which destroys the apple orchard agroecosystem. The investigation was aimed at developing… (More)
Coccophagus tetrastichoides sp. n. is characterized by an uncommon combination of features, particularly, by the general habitus and by the submarginal and marginal veins connected as those in tetrastichine wasps. C. tetrastichoides sp. n. is a gregarious parasite of adult females of the myrmecophilous soft scale, Megalocryptes bambusicola Green, setting on… (More)
The species diversity and number of zoophagous arthropods as estimated by Margalef’s d index (1958) are the main biological sources of agroecosystem stability. This fact forms the basis of the ecological pest and its enemy management (EPEM) program, which has demonstrated high technical and ecological efficiency, the former referring to the main task of… (More)
Coccophagus thanhoaensis sp. n. is described; it differs from the closely related C. tschirchii Mahdihassan in the following characters: mandibles with two teeth and undulate truncation; anterior part of mesoscutum with V-shaped blackish spot; middle coxae blackish; abdomen moderately pointed at apex.
A new genus, Neoanabrolepis gen. n. with the type species N. valentinae sp. n., parasitoid of the soft scale Asterolecanium sp. on bamboo in Vietnam, is described in the tribe Habrolepidini Hoffer.
Specialized morphological and biological adaptations of immature and adult phases of the species, providing its final reproductive success, form the basis for the formation of three types of parasitizing strategies (macrobiontic, ephemerobiontic, and mediobiontic) in parasitic wasps. The macrobiontic strategy, typical of specific species, solves the task of… (More)

A new species, Ericydnus novosibiricus sp. n., is described. The main characters differentiating the new species from the similar E. longicornis Dalman are as follows: female—fore wing noticeably shortened, with almost normally developed veins and rounded apex, marginal vein longer than postmarginal vein, 6th flagellar segment slightly longer than wide,… (More)
A general technological scheme of integrated ecological management of lepidopterous rice pests is proposed. The suggested algorithm comprises the following principal elements: (1) two-level economic threshold of damage (TETD) for the rice leaffolder (Chaphalocrocis medinalis); (2) TETD for the yellow stemborer (Scirpophaga incertulas); (3) monitoring of the… (More)
Coccophagus brachypterus sp. n. is described from Malaysia. The new species differs from the closely related C. silvestrii Compere in the black hind femur and blackish largest part of hind tibia. The new species is also characterized by shortened fore wings with the apices not reaching the abdominal apex.
