Abstract
Tuta absoluta is one of the most important pests of tomato in many countries. Emamectin benzoate (EB) is widely used in the control of lepidopteran pests, but there is sparse information available regarding its sublethal effects on T. absoluta. In this research, the lethal and sublethal effects of EB were investigated on T. absoluta under laboratory conditions. Acute toxicity bioassay was carried out on 2nd instar larvae using residue contact method. The LC50 value was 14.50 mg a.i. L−1, for 24 h exposure time. LC10 and LC30 of the insecticide was used for sublethal effect study. The insecticide significantly extended the larval developmental time at LC30. Pupal weight, fecundity and longevity of female adults were decreased at both tested concentrations. However, the LC10 and LC30 of the insecticide had no significant effects on pupal period, egg hatchability, and male adults’ longevity at sublethal effect study. These results suggest that the sublethal effects of EB might affect pest population dynamics significantly by delaying its development, and decreasing its reproduction. Hence, this bioinsecticide can be used in integrated pest management program of T. absoluta if its efficacy proven under the field and greenhouse conditions.

چکیده [English]

چکیده
 شب­ پره مینوز گوجه­ فرنگی،Tuta absoluta ، یکی از آفات مهم گوجه­ فرنگی در بسیاری از کشورها می­ باشد. حشره­ کش امامکتین­بنزوات به طور گسترده برای کنترل آفات بال پولکدار بکار برده می­شود ولی اطلاعات کمی درباره اثرات زیرکشندگی آن روی T. absoluta موجود است. در این مطالعه، اثرات کشندگی و زیرکشندگی امامکتین بنزوات روی T. absoluta تحت شرایط آزمایشگاهی بررسی شد. زیست­سنجی سمیت حاد روی لاروهای سن دوم T. absoluta با روش تماس با باقیمانده سم انجام شد. مقدار LC50  بدست آمده امامکتین بنزوات 50/14 میلی­ گرم ماده موثره بر لیتر پس از 24 ساعت در معرض قراردهی بود.  LC10و LC30 حشره­ کش برای بررسی اثرات زیرکشندگی استفاده شد. حشره­ کش به طور معنی ­دار طول دوره لاوری را در غلظت LC30 افزایش داد. وزن شفیرگی، باروری و طول عمر بالغین ماده­ها در هر دو غلظت زیرکشنده کاهش یافت. با این حال، در بررسی اثرات زیرکشندگی، LC10 و LC30 حشره ­کش اثر معنی ­داری روی طول دوره شفیرگی، درصد تفریخ تخم و طول عمر بالغین نر نداشتند. این نتایج نشان می­دهد که غلظت­های زیرکشنده امامکتین ­بنزوات می­ توانند با به تعویق انداختن دوره رشدی و کاهش تولیدمثل، اثرات منفی بر دینامیسم جمعیتT. absoluta  داشته باشند. بنابراین، این حشره­ کش زیستی در صورت ثابت شدن کارایی در شرایط مزرعه و گلخانه می­ تواند در برنامه ­های مدیریت تلفیقی علیه T. absoluta بکار رود.
