Abstract
The article considers the issues related to the development of the methods of biological crop protection against the adventive species of pentatomides (Pentatomidae, Hemiptera) – the southern green stink bug Nezara viridula L. 1758. One of the main factors contributing to the significant spread of this multinucleated pest is the lack of effective control systems of this species, in particular, poor knowledge of local entomophages species. A number of the biological peculiarities of a stinkbug has been studied. For the first time in the Russian Federation, infection of the N. viridula eggs with the entomophage Trissolcus basalis Woll. 1858 (Hymenoptera: Scelionidae) was determined We found that to control Nezara in such crops as soybeans, tomatoes and tobacco, it is possible to use the Fitoverm-M preparation (active ingredient – aversectin-C, 2 g/l).
Highlights
Agrocenoses are under the constant influence of various environmental factors, both biotic, abiotic, and anthropogenic, associated with the large-scale globalization [1]. This has led to the fact that over the past decade, a number of stinkbugs such as Nezara viridula L. 1758, Halyomorpha halys Stål, 1855, Piezodorus guildinii Westwood, 1837, Megacopta cribraria Fabricius 1798, have expanded their habitats and acquired the status of invasive pests in many countries of the world [1, 2]
The research was carried out on the basis of a ten-field grain-hoed crop rotation of the AllRussian Research Institute of Biological Plant Protection (ARRIBPP) on soybean Arleta and Vilana varieties (0.01 ha plots were selected for testing the biological product) and on Yubileiny Novy 142 tobacco crops and on tomato Gaidas variety in the All-Russian Research Institute of Tobacco, shag and tobacco products (ARRITTP)
Laboratory testing of suspensions of entomopathogenic nematodes (EPNs) was carried out in Petri dishes, where the N viridula imagoes were treated with invasive larvae of EPNs at a dose of 100 ind. on one insect, germinated mash seeds were placed in the dishes, serving as food for Nezara, and a moist cotton swab, providing favorable conditions for maintaining insects
Summary
Agrocenoses are under the constant influence of various environmental factors, both biotic, abiotic, and anthropogenic, associated with the large-scale globalization [1]. The information available in the literature, as well as the data on the constantly growing number of the pest in Krasnodar Krai, indicate the need to develop techniques for an effective system of biological protection against N. viridula.
