Box 31485/498, Karaj, Iran Journal Article 2016 11 06 The cotton aphid, Aphis gossypii Glover is a major pest of greenhouse cucumber in the world. In this study, age specific functional response of Aphidius matricariae Haliday and Praon volucre (Haliday) were investigated on A. gossypii at 25±1°C, 60±5% RH and a photoperiod of 14 L: 10 D h. The results showed that the functional response of A. matricariae was type III during 1st, 2nd, 3rd, 4th and 5th days and type II in 6th day of adult parasitoid lifetime. The type of functional response of P. volucre was type II in whole parasitoid lifetime. The highest b value (0.02±0.003 h-1) and the lowest handling time (Th) (0.70±0.013 h) of A. matricariae were observed in the 1st day of parasitoid lifetime. The maximum attack rate (T/Th) of A. matricariae occurred in the first day of parasitoid lifetime (34.28 nymphs). The maximum searching efficiency of P. volucre was determined in the 2nd and 3rd days (0.03±0.003 and 0.03±0.005 h-1) and the minimum handling time was recorded in the 2nd day (0.97±0.140 h) of adult female life. The maximum parasitism rate was 24.74 nymphs in the two day old female, and then decreased in adult female age. The results suggest that A. matricariae and P. volucre are highly effective biological agents in suppressing A. gosspii population on cucumber in greenhouses. شته جالیز، Aphis gossypii Glover یکی از آفات مهم خیار گلخانهای در جهان است. در این تحقیق واکنش تابعی وابسته به سن زنبورهای پارازیتویید Aphidius matricariae Haliday و Praon volucre (Haliday) روی شته A. gossypii در شرایط آزمایشگاهی 1±25 درجه سلسیوس، رطوبت نسبی %5±60 و دوره نوری 14 ساعت روشنایی و 10 ساعت تاریکی مورد بررسی قرار گرفت. نتایج نشان داد که واکنش تابعی زنبور A. matricariae در روزهای اول، دوم، سوم، چهارم و پنجم عمر زنبور پارازیتویید از نوع سوم و در روز ششم عمر از نوع دوم بود. واکنش تابعی زنبور پارازیتویید P. volucre در تمام عمر زنبور پارازیتویید از نوع دوم بود. بیشترین مقدار b (003/0±02/0 بر ساعت) و کمترین مقدار زمان دستیابی (Th) (013/0±70/0 ساعت) زنبور A. matricariae در روز اول عمر زنبور پارازیتویید بود. بیشترین مقدار حداکثر نرخ حمله زنبور پارازیتویید A. matricariae برابر 28/34 پوره و در روز اول عمر زنبور پارازیتویید مشاهده شد. بیشترین مقدار قدرت جستجوگری زنبور پارازیتوییدP. volucre در روزهای دوم و سوم (003/0±03/0 و 005/0±03/0 بر ساعت، به ترتیب) عمر زنبورهای پارازیتویید ماده بدست آمد. کمترین زمان دستیابی زنبور پارازیتویید P. volucre برابر 140/0±97/0 ساعت و در روز دوم عمر زنبور پارازیتویید بود. همچنین بیشترین مقدار T/Th این زنبور پارازیتویید در روز دوم عمر و برابر 74/24 و در روز دوم عمر بدست آمد، سپس با افزایش عمر مقدار این پارامتر کاهش یافت. نتایج حاصل از این تحقیق نشان داد که دو گونه زنبور پارازیتویید A. matricariae و P. volucre میتوانند به عنوان عوامل کنترل بیولوژیک مؤثر در کاهش جمعیت شته A. gossypii روی گیاه خیار در گلخانهها در نظر گرفته شوند.

Sahragard Department of Plant Protection, Faculty of Agricultural Sciences, Guilan University, Rasht, Iran. R. Jalalipour Kh. Madahi PhD student A. Karimi-Malati Academic staff Journal Article 2016 09 14 -The cowpea aphid, Aphis craccivora Koch, is an important pest of Robinia pseudoacacia Frisia. Life table parameters of A. craccivora were determined under natural (16- 33ºC and 32-89% RH, respectively) and laboratory (25 ± 1ºC, RH of 70 ± 5% and a photoperiod of 16:8 h (L: D) conditions. The data were analyzed using the age-stage, two-sex life table theory. Each experiment was replicated 45 times for each condition. There was significant differences between the survivorship, fecundity and longevity of the A. craccivora in laboratory and natural conditions. Under natural conditions, A. craccivora had a significant shorter nymphal developmental time, adult longevity and life span than those reared under laboratory conditions. However, the intrinsic rate of increase (r), net reproductive rate (R0), the finite rate of increase (λ) and gross reproductive rate (GRR) under laboratory conditions, were higher than those obtained in field, the higher mean generation time (T) was found in the field. All in all, the results of this study showed that two different conditions (field and laboratory) had significant influence on developmental times and life table parameters of A. craccivora and it is hard to escape the obvious conclusion that we must prevent the unsuitable extrapolation of laboratory results to field applications. The results obtained here, could also help us to understand the population dynamics of A. craccivora under field condition and to develop effective integrated pest management (IPM) programs. شته اقاقیا، Aphis craccivora Koch آفت مهم اقاقیا، Frisia Robinia pseudoacacia است. ویژگیهای جدول زندگی A. craccivora در شرایط طبیعی (دمای 16-33 درجه سلسیوس و رطوبت نسبی 32-89 درصد) و آزمایشگاهی (دمای 1±25 درجه سلسیوس، 5±70 درصد و دوره نوری 16 ساعت روشنایی و 8 ساعت تاریکی) تعیین شدند. دادهها با استفاده از نظریه سن- مرحله جدول زندگی دوجنسی تجزیه و تحلیل شدند. آزمایشها در هر کدام از شرایط 45 بار تکرار شدند. تفاوت معنیداری بین بقا، باروری و طول عمر A. craccivora در شرایط آزمایشگاهی و طبیعی وجود داشت. در شرایط طبیعی، A. craccivora به طور معنیداری طول دوره پورگی، طول عمر حشرات کامل و چرخه زندگی کوتاهتری نسبت به شرایط آزمایشگاهی داشت. به هرحال، نرخ ذاتی افزایش (r)، نرخ خالص تولید مثل (R0)، نرخ متناهی آفزایش جمعیت (λ) و نرخ ناخالص تولید مثل (GRR) در شرایط آزمایشگاهی بالاتر از مقادیر به دست آمده در شرایط طبیعی بودند. در هر حال، مدت زمان نسل در شرایط طبیعی طولانیتر از شرایط آزمایشگاهی بود. به طورکلی، نتایج این مطالعه نشان داد که شرایط متفاوت (مزرعه و آزمایشگاه) تاثیر معنیداری روی دورههای رشد و ویژگیهای جدول زندگی A. craccivora داشتند و گریز از نتیجهگیری آشکار مبنی بر این که باید از تعمیم نامناسب نتایج آزمایشگاه برای کاربرد در شرایط طبیعی جلوگیری کنیم، سخت است. نتایج به دست آمده در اینجا میتواند در درک پویایی جمعیت A. craccivora در شرایط مزرعه و توسعه برنامه مدیریت تلفیقی موثر نیز به ما کمک کند.

Cold hardiness strategy of the beet moth larvae was investigated through monitoring seasonal changes at supercooling points and lower lethal temperatures. Furthermore, the role of microhabitat in winter survival was studied. The mean SCPs of the last instar larvae was not significantly different from November 2010 to April 2011. Mean inoculative freezing point (-8.0 ± 1.44 °C) of the last instar larvae was significantly higher than mean SCP (-14.9 ± 0.93 °C). The cold hardiness of the pest shows seasonal fluctuation in response to reduction of air temperature. A 50% mortality (LT50) occurred at -11 ºC in November and -14 ºC in January and reduced to -18 ºC in February and finally increased to -14.5 ºC in April. Glycerol, sorbitol, trehalose, and myo-inositol were identified components in whole body extracts of S. ocellatella larvae. However, total cryoprotectants could not have significant effects on the cold tolerance. Larvae of S. ocellatella could tolerate subzero temperatures near their SCPs. Our findings show that beet moth larvae utilize moderately chill tolerance strategy during winter. The beet moth, Scrobipalpa ocellatella is recognized as a widespread agricultural pest.

R. Lashkari Fariba Mozaffarian M. Mehrparvar Department of Biodiversity, Institute of Science and High Technology and Environmental Sciences, Graduate University of Advanced Technology, Kerman, Iran Journal Article 2016 10 31 Dubas bug, Ommatissus lybicus de Bergevin (Hem.: Tropiduchidae), is a key pest of date palms in Iran.This pest was first reported on date palms in 1966 and has been established throughout the date producing regions in southern Iran since. Date palm is the only host plant of Dubas bug. It attacks almost all date palm varieties, esp. Mazafati variety in city of Bam, Kerman Province and other varieties such as Halilei and Karoot. Using geometric morphometric method on forewings, we studied the morphological characters of host-associated populations of this pest. Adult Dubas bugs were collected on three varieties of date palms, Phoenix dactylifera L., including: Mazafati, Halilei and Karoot from Bam in 2015. For the analysis of wing shape and wing size, MANOVA and ANOVA were done, respectively. An allometric analysis was performed on the shape and size variables. The results of MANOVA indicated a significant difference (P<0.05) among wing shapes but no difference observed among wing sizes (P >0.05). The regression of shape on the size variables showed no significant allometric growth (P >0.05). The UPGMA tree, based on the Mahalanobis distances matrix, detected two distinct groups: the first group was a population feeding on the Mazafati variety with narrow wing shapes, and the second were populations feeding on Halilei and Karoot varieties with wide and shorter wing shapes. The observed forewing shape of individuals in population feeding on the Mazafati variety may change their flight abilities, and other biological aspects, such as survival.
