Abstract

Disorientation of the plum moth (Grapholita funebrana Treitschke) under the conditions of chemical protection of the garden was carried out using dispensers (Z8DDA, 16.7 mg) produced by ZAO Shchelkovo Agrokhim. Dispensers were placed at a tree trunk at a height of 1.5 - 2 m with an application rate of 500 per hectare. The study was carried out on three plots of a 1 ha plum orchard: a plot with chemical treatments and with disorientation, an area with chemical treatments, without disorientation, and an area without chemical treatments and without disorientation. The effectiveness of disorientation at a high abundance during the flight peaks of the second and third generations of the pest ranged from 100 % to 92-93 %. The effectiveness of disorientation, together with the chemical protection of the garden in comparison with untreated area, showed higher results - in the first two months, the efficiency ranged from 100 to 98 %, and during the periods of the 2nd and 3rd flight peaks of the pest (with a flight intensity of 136 - 120 individuals per trap) did not fall below 96 %.

Highlights

The economic significance of the plum moth (Grapholita funebrana Treitschke) is quite large, it damages cherry plums, blackthorns, plums, apricots, peaches, flowering plum, bird cherry of Maksimovich, cherry, including Japanese or Korean, shrub or steppe and felt, cherry or sogssurian pear, and was noted in the Dahurian rosehip and in the hawthorn [1, 2, 3]
The largest number of works on the use of control during the flight of imago is associated with the use of pheromones [15, 16, 17In general, the method appeals to the agricultural service, both due to the duration of action and the economy of use, and recent studies have already made it possible to develop a bait with a sufficiently long period of action that allows the use of single-use dispensers for the plum moth for the entire period of crop protection [18]
This paper discusses the role of the method of disorientation of the plum moth Grapholita funebrana Treitschke using long-term dispensers for different pest numbers

Summary

Introduction

The economic significance of the plum moth (Grapholita funebrana Treitschke) is quite large, it damages cherry plums, blackthorns, plums, apricots, peaches, flowering plum, bird cherry of Maksimovich, cherry, including Japanese or Korean, shrub or steppe and felt, cherry or sogssurian pear, and was noted in the Dahurian rosehip and in the hawthorn [1, 2, 3]. Since young larvas that have begun to take root in the fruit are able to reduce the saleable condition due to the release of gum from damage, protection at earlier stages is advisable This will reduce the harm from larvas hatching from eggs, but because treatment during oviposition by many groups of drugs is ineffective, and their use at the beginning of hatching, with extended periods of hatching of larvae from eggs, is often economically unjustified and is available only to highly trained specialists. The largest number of works on the use of control during the flight of imago is associated with the use of pheromones [15, 16, 17In general, the method appeals to the agricultural service, both due to the duration of action and the economy of use, and recent studies have already made it possible to develop a bait with a sufficiently long period of action that allows the use of single-use dispensers for the plum moth for the entire period of crop protection [18]. This paper discusses the role of the method of disorientation of the plum moth Grapholita funebrana Treitschke using long-term dispensers for different pest numbers
