PLUM FRUIT MOTH (GRAPHOLITA FUNEBRANA, TR.): MONITORING AND STUDY OF FLIGHT CURVE DYNAMICS OF ADULT MALE MOTHS IN RELATION WITH CLIMATIC FACTORS AT RSFG BISTRITA IN THE PERIOD OF 2016-2018
Journal Title: FRUIT GROWING RESEARCH - Year 2018, Vol 0, Issue
Abstract
The main objective of the study was the monitoring of flight curve of adult plum fruit male moths (Grapholita funebrana, Tr.) analyzing scientific data from an interval of 3 experimental years (2016-2018). The aim of the study was to find out the maximum of flight curve, the study of the biology and develoment of adult moths. There were used specific ATRAFUN pheromonal traps buyed from ICCRR ‘Raluca Ripan’ Institute, the atractant was Z8 dodecen 1-il and E8 dodecen 1-il acetate, traps were plased in an older plum orchard planted with Stanley, Renclod Althan and other cultivars grafted on Myrobalan. In the experimental years 2016-2018 adult male moths appeared relatively close in time, in May (30.05.2016, respectively 24.05.2017, and in 22.05.2018 in the year 2018). In 2016, in the period of maximum flight, the number of adult male moths captured was between 1-22 moths/trap and in year 2017 between 12-19 moths/trap. It was observed that in rainy periods in the moths June-July 2016-2017 and especially in 2018, when there were registered high rainfall amounts in May and June; the number of adult moths captured was lower in comparison with warm, sunny days. In the year 2018 at the beginning of observation period (at the end of May) there were captured in average 12-17 adult moths. At the beginning and the middle of June when the temperatures were favorable, when was registered the maximum flight for 2018, there were registered 13-17 adult moths / trap. At the end of month June there were registered high amounts of rainfall and lower temperatures, thus the development and flight of the pest was more reduced. July 2018 was characterized as a cold, rainy month, there were registered a much lower flight (2-5 adults /trap). If we analyze the maximum flight curve of the three experimental years than the conclusion is that in 2016it was registered the maximum, in decade III of moth June, capturing 22 adults. In 2017 the maximum flight curve was registered in decade III of July with 16 adults and in 2018 the maximum was in the middle of June, decade II, with 17 adult male moths registered. These scientific dates are very important in order to identify the maximum flight curve and to find those periods when the phytosanitary treatments have the greatest efficiency.
