اثر دورکنندگی حشره‌کش‌های گیتازئوس و روی‌آگرو بر حشره کامل مگس میوه مدیترانه‌ای در باغ مرکبات

Currently, one of the most important pests of fruit trees, especially citrus fruits, in Mazandaran province is the Mediterranean fruit fly (Ceratitis capitata (wiedemann)). Considering that Mazandaran is considered one of the important citrus production provinces in Iran, therefore, knowledge of the correct management methods of this pest is an important issue. Therefore, in this research, from RuiAgro (Matrine 0.6% SL) as an organic insecticide on the repellent and inhibition of Mediterranean fruit fly spawning compared to the chemical insecticide GitaZeus (Thiacloprid Deltamethrin 11% OD), a penetrating insecticide (semi-systemic) with contact and digestion was investigated in garden conditions. This study was conducted in a three-hectare citrus orchard of Citrus reticulate of Miyagawa cultivar located in Sari city. The experiment was carried out in the form of split plots in the form of a randomized complete block design. The test factors included insecticide (GitaZeus, RuiAgro and control (sprinkling)) and time (10 weeks of statistics). Each insecticide treatment was tested in three replicates and 3 trees in each replicate. At first, the number of healthy and infected fruits of each tree was counted and the infected fruits were collected from the base of the trees. Investigations were carried out based on infected fruits on the tree and under the tree. The fruits under the tree were transferred to the laboratory to check the presence or absence of Mediterranean fruit fly larvae. Also, the fruits on the tree suspected to be damaged by C. capitata were marked and examined later. Their results showed that in all 10 weeks evaluated, GitaZeus poison showed a lower percentage of infected fruits than RuiAgro and control. In the first seven weeks of evaluation, the insecticide on RuiAgro had a lower percentage of fruit contamination than the test control. But in the final weeks (8th, 9th and 10th weeks), this insecticide showed a higher percentage of infected fruits than the test control. So that the average percentage of fruit contamination during 10 weeks of statistics for each tree was 0.47% for GitaZeus, 1.97% for RuiAgro and 1.82% for control. In this study, Gitazeus chemical insecticide was more effective in controlling C. capitata than the organic insecticide on RuiAgro.
