بررسی تاثیر چند حشره کش بر روی سوسک شاخک بلند پسته

‭The Long-horned beetle (Calchaenesthes pistacivora) a new pistachio (Pistachio vera) and wild pistachio (Pistachio mutica) pest was found in pistachio orchards of Sirjan (Kerman province) in April, ‬‮‭1999‬‭. This insect has one generation over two years. The larvae feed on inside tissues of the pistachio branches and make a large tunnel. The infected branches become dry and so this pest cause heavy damage on pistachio trees. In order to chemical control ‬3 ‭insecticides, such as: Diazinon, Endosolfan each one with and without Volk oil and Neem Azal- T/S were used in the adult appearance peak period. This experiment was designed in the Randomize complete block designs with ‬4 ‭replication. Also two insecticides, such as: Phosalone + Tiflubenzuron and Admiral each one with and without volk oil on the egg and first instars larvae stages were tested. The results showed that; ‬‮‭14‬ ‭day after spraying, Endosolfan and Diazinon with and without volk oil with ‬‮‭100‬‭% and ‬‮‭100‬‭% respectively are effective on the adult. Neem Azal T/S with ‬‮‭50‬‭% effective in the adult has significantly difference with other treatments and it was ineffective. Admiral with ‬‮‭3.86‬‭% is effective on the egg and first instars larvae stages. The results indicated that, the adult beetles are very sensitive to the insecticides and it could be controlled in the field if insecticides application is managed in correct order and right time.‬
