Abstract

This paper presents our results in use of the specialized software and specific modules for microclimate monitoring and pest biological cycle assessment, to evaluate and quantify the attack risk for microclimate monitoring, combined with 6 type specific pheromones produced in Romania, in order to determine their efficacy in detecting the targeted micro Lepidoptera, assess their population flight pattern, as well and the biocenotic stress, both tools categories aiming to the precise positioning of the treatments to achieve integrated pests management and reduce the overall impact of the treatments with insecticides on the environment. According the fruit species, several strategies have been defined and followed by several insecticide applications into the bearing orchards, to achieve a better control of damaging micro Lepidoptera. Use of the mixed monitoring systems in tandem with specific pheromones contributed to a more efficient use of the insecticides and increased performances, both for pome and stone fruit species as well.

Highlights

This paper presents our results in use of specialized software for microclimate monitoring in order to determine their effectiveness in targeted micro Lepidoptera detection, assessment of their population flight pattern, as well as the expert software modules for microclimate monitoring and pest biological cycle assessment
The goal was to evaluate and quantify the attack risk as well as specific pheromones produced in Romania, to assess the biocenotic stress, both tools categories aiming to the precise positioning of the treatments to achieve integrated pests management and reduce the overall impact of the treatments with insecticides on the environment
According the location the average and maximum air temperature influenced the speed of the pest development, to complete the biological cycles of the generations and to initiate the attack in the orchards

Summary

Introduction

In the fruit growing sector, many technical and socio-economic changes occurred, which turn this into an intensive and complex activity. Important amounts of fruits and derivate are put on the market to satisfy the increasing demand and very exigent consumers as well. In Europe, the average mean productions of pome fruits was 8,238,585 t apples and 429,340 t pears/year, harvested from 989,294 respectively 163,815 ha. The most important apple producing countries are: Poland, Italy, France, and Germany. Romania is producing in average 488,773 t apples annually, from 54,970 and respectively 51,972 t pears from 3,137 ha. The plum harvested surface in Europe was 381,602 ha, with a mean production of 2,539,868 t/year. The most important plum producing countries were: Romania, Serbia and Bulgaria, followed by Turkey. Romania is producing in average 558,356 t plums / year, from 65,985 ha
