Message:
Abstract:
Cherry fruit fly Rhagoletis cerasi L. is a key pest and one of the important pests of cherry and sour cherry varieties in Iran. After mating adult Female insert eggs under the peel of late cherry varieties with their ovipositor at the time of fruit color change. Larvae develop inside the fruit and feed on the fruit flesh within the fruit. At present, 1 to 3 times spraying are carried out to control this pest in different parts of the country. This study was carried out in Karaj and Bojnord regions during 2007 and 2008. In order to reduce environmental pollution and the use of pesticides, One and two times spraying of Hydrolyzed Protein and malathion (malathion® EC 57%) at the lower one third of the tree canopy, once and two times spraying of the tree trunks to a height of 2 meters above the ground with spinosad (GF-120), two and three times spraying of the tree trunks to a height of 2 meters above the ground with hydrolyzed protein and malathion, with control treatment and spraying the entire tree canopy (conventional method) was used. The aim was to attract the adult pests so as to feed and absorb the pesticides and the toxic compound and to destroy them. Assessment was performed by random observation of 160 fruits per replicate. Results indicated that out of seven experimental treatments, spraying of malathion and hydrolyzate protein on one-third of lower part of tree canopy twice a season in 1386 in Bojnord (mean±SE:4.42±0.674) and Karaj (mean±SE: 4.3775±0.57) and doing the same procedure in following year, 2008, in above mentioned locations, Bojnord (mean±SE: 2.243±0.227) and Karaj (mean±SE: 2.815±0.65), along with using poison baits sprayed on bark from soil surface to 2m higher with of malathion and hydrolyzate protein in 3 times in the year 2007 in Bojnord (mean±SE: 3.597±0.18) and Karaj (mean±SE: 4.69±0.83) and doing the same procedure in following year, 2008, in Bojnord (mean±SE: 4.848±0.93) and in Karaj (mean±SE: 1.407±0.24) and also spraying with spinosad (GF- 120®) on bark from soil surface to 2m higher in the year 2007 in Bojnord (mean±SE: 3.5975±0.47) and in Karaj (mean±SE: 4.22±0.24) and doing the same in following year, 2008, in Bojnord(mean: 4.484±1.23) and in Karaj (mean±SE: 2.97±0.497) had it best results.
