بررسی اثر سموم کلروپیریفوس و پیری پروکسی فن جهت کنترل سرشاخه‌خوار پیراکانتا

Pyracantha with its scientific name (Pyracantha coccinea) from the Rosaceae family, is an evergreen and thorny shrub with shiny green, oval leaves, which is mainly grown to create privacy and plant protection, especially in cold areas. Its fruits are orange, red and sometimes yellow, which appear in autumn and winter. In terms of beauty, it is used in green spaces, but in recent years, the branch-eating pest has been observed on it.
The branch-eating beetle, which in the past decades was known as one of the secondary pests for different hosts, including cold-fruit trees with kernels and seeds, is now one of the important pests of trees with the occurrence and continuation of drought. And the shrubs of the green space have been transformed. It causes severe damage to the host trees. Due to the hiddenness of the pest larvae inside the branches of the host trees, chemical control is not effective against it.
Management methods such as spraying can affect the pest insects, so in order to investigate the effect of chemical poisons on the amount of damage caused by Pyracantha in the municipality of 15th district of Tehran, a research project was implemented in the form of a randomized complete block experiment in three replications. Spraying was done in 3 times, including Chlorpyrifos, Pyriproxyfen, Pyriproxyfen + Chlorpyrifos and distilled water controls.
