Aphis gossypii is one of the factors that reduce chili production which acts as a pest and virus vector. This research aimed to determine effectiveness application neem cake water extract A. on red plants. consisted 2 experimental stages, namely in laboratory greenhouse trials. The design used completely randomized with treatments A (Control), B (0.3%), C (0.6%), D (1.2%), E (2.4%), F (4.8%). E...
شته ی سبز پنبه (aphis gossypii glover) از آفات مهم پنبه (gossypium hirsutum l.) در مزارع پنبه ی منطقه ی گرگان می باشد. طی سال های 1381 و1382 با ساخت جدول زندگی سنی در شرایط مزرعه، پارامترهای دموگرافیکی جمعیت شته در مقاطع مختلف از فصل زراعی برآورد گردید. با استفاده از ماتریس انتقال جمعیت، میزان حساسیت نرخ رشد جمعیت شته به تغییرات احتمالی در مقادیر نرخ های بقا و باروری ارزیابی شد. در اوایل فصل (ت...
The focus of this study was on quantifying fitness attributes, such as spore density and viability, and determining the virulence level against aphid (Aphis gossypii) nymphs of isolates from the fungal species Beauveria bassiana and Metarhizium anisopliae. The fungal isolates were obtained from several insects, including Plutella xylostella, Hypothenemus hampei, Bronstispa longissima, A. gossyp...
Aphis gossypii Glover is one of the most important pests of greenhouse cucumber and pepper in the world and Iran. In this research, life table and biology of A. gossypii were investigated on cucumber (Cucumis sativus cv. Super Sultan) and pepper (Capsicum annum cv. Marqueza) in a growth chamber at 25±1°C and 60±5% RH and a photoperiod of 14 L: 10 D hour. The results showed that developmental ti...
Aphis gossypii Glover and Acyrthosiphon Mordvilko (Hemiptera: Aphididae) are key pests of cotton, Gossypium hirsutum L., known to induce cotton host plant defense responses. Deep RNA sequencing the transcriptome followed by differential expression analyses were performed clarify molecular mechanisms in response feeding these aphid pests. We found 6,565 genes differentially expressed Ac. 823 tha...
شته پنبه aphis gossypii glover. یکی از مهمترین آفات محصولات زراعی و گلخانه ای در سرتاسر جهان محسوب می شود. مشکلات ناشی از مصرف آفت کش ها، موجب استفاده روزافزون از عوامل کنترل بیولوژیک مثل قارچ های بیمارگر حشرات شده است. بررسی حاضر با استفاده از قارچ های lecanicillium lecanii و beauveria bassiana انجام گرفت. هدف از انجام این پژوهش، بررسی کارایی قارچ های مذکور به شکل تلفیقی و جداگانه بر میزان مرگ...
Aphis gossypii Glover is a polyphagous aphid pest with a worldwide distribution. However, there is evidence that on a global scale the name A. gossypii is being applied to a number of forms with different life cycles and/or host-plant associations. Morphometric variation of A. gossypii samples from crops and non-cultivated plants in many parts of the world was examined, to determine whether thi...
This article documents the addition of 396 microsatellite marker loci to the Molecular Ecology Resources Database. Loci were developed for the following species: Anthocidaris crassispina, Aphis glycines, Argyrosomus regius, Astrocaryum sciophilum, Dasypus novemcinctus, Delomys sublineatus, Dermatemys mawii, Fundulus heteroclitus, Homalaspis plana, Jumellea rossii, Khaya senegalensis, Mugil ceph...
Cotton produces insecticidal terpenoids that are induced by tissue-feeding herbivores. Damage by Heliothis virescens caterpillars increases the terpenoid content, which reduces the abundance of aphids. This effect is not evident in Bt-transgenic cotton, which is resistant to H. virescens. We determined whether induction of terpenoids by caterpillars influences the host quality of Aphis gossypii...
