بررسی وضعیت آفات در روش آبیاری قطره‌ای زیرسطحی در مقایسه با سیستم آبیاری جویچه‌ای در نیشکر

Subsurface drip irrigation with guided application ‌of water in the root area, removal of runoff -and reduction of water losses, has resulted in saving water consumption, which, if properly managed, maintains soil moisture in an optimal condition. In ‌order to investigate the effect of changing the irrigation method from a well ‌to ‌a subsurface drip on the severity and prevalence of important sugarcane pests such as ‌sugarcane stem bore (Sesamia spp.) and ‌sugarcane root beetle Pentodon idiota Herbs (col., Scarabeide) was examined . These investigations were carried out in a subsurface drip irrigation farm(S06-01 with an area of 21.6 hectares and a comman furrow irrigation farm S06-03 with an area of about 25 hectares, in Hakim Farabi Sugarcane agro- Industry Company. The variety cultivated in these two farms is CP69-1062. So,10 ), 10 light traps were installed in each field. The heads of these traps ‌were photocell type. And the bases were ‌telescopically adjustable with the height of the canes. ‌ Caught moths and root- eating ‌beetles ‌were counted daily, and data ‌were recorded. The pans ‌of these traps ‌were drained daily to prevent moths from escaping. By investigating the hunting rate ‌of Sesameia moths, the root- ‌eating beetle ‌, by ‌optical traps in two farmsS06-01 ( ‌subsurface drip irrigation) and farm S06-03 (furrow irrigation ‌) was counted. The hunting rates ‌of moths and pentadon beetles ‌were significantly higher in the subsurface drip ‌irrigation field . ‌The highest amount of Sesamia moth hunting ‌occurred ‌in September in the subsurface irrigation field with 6969 numbers and the lowest amount of Sesamia moth hunting occurred in June incommon irrigation field with 391 numbers ‌. The highest hunting rate of pentadon beetle occurred ‌in September in the subsurface irrigation farm with 1378 numbers and the lowest hunting rate of the root-eating beetle was in July in the Juichei irrigation farm with 333 numbers ‌. Due to the fact that subsurface drip irrigation has caused changes in the pattern of the agricultural system, and in this plan, furrow irrigation, ‌which is one of the ways ‌to control root-eating pests, is ‌not implemented, ‌and due to the stress ‌on the plant, It is recommended ‌to use integrated methods of irrigation and ‌pest ‌control
