Selection of Reference Genes for Expression Analysis in Diuraphis noxia (Hemiptera: Aphididae) Fed on Resistant and Susceptible Wheat Plants
The Russian wheat aphid (RWA), Diuraphis noxia Kurdjumov, is a major global pest of wheat and barley production that causes enormous economic damage. Few studies have been conducted to explore and decipher the molecular basis of RWA strategies to evade plant defense mechanisms. Gene expression studies of RWA in response to wheat genotypes carrying different RWA resistance genes have been initia...

نرخ شکارگری اساس هر پژوهش در برهم‌کنش شکار-شکارگر است و یکی از اجزای مهم در انتخاب شکارگران در کنترل بیولوژیک بهشمار میرود. نرخ شکارگری کفشدوزکHippodamia variegata (Goeze) با تغذیه از تراکمهای مختلف (20، 40، 60، 80 و 100) عدد از پورههای سن سوم شته پنبه Aphis gossypii Glover در شرایط آزمایشگاهی (1±25 درجه سلسیوس، رطوبت نسبی 5 ±65 درصد و دوره نوری 16 ساعت روشنایی و 8 ساعت تاریکی) بررسی شد. ...
متن کاملduration of life stages and fecundity of diuraphis noxia (hemiptera: aphididae) on six wheat cultivars
the russian wheat aphid (rwa), diuraphis noxia has been known as a major pest of small grains, particularly wheat, worldwide. this study evaluated the biological responses of rwa to six wheat cultivars including yavarus, pishgam, aadl, omid, darab 2 and sepahan. the experiment was conducted under greenhouse conditions of 25 ± 2 °c, 55 ± 10 % r. h. and a photoperiod of 16:8 (l: d) h. resistance ...
متن کاملeffect of two resistant and susceptible wheat cultivars on biology and predation rate of hippodamia variegata by feeding from diuraphis noxia
in this study, the possible effects of host plant resistance on some demographic parameters and predation rate of hippodamia variegata goeze life stages have been investigated. demographic data and predation rate have been analyzed by the age-stage two-sex life table and consumption rate program. obtained results showed that preadult diuration and total preoviposition period (tpop) of ladybirds...
متن کاملImpact of Diuraphis noxia and Rhopalosiphum padi (Hemiptera: Aphididae) on primary physiology of four near-isogenic wheat lines.
The impact of feeding injury by the Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae), and bird cherry-oat aphid, Rhopalosiphum padi (L.) (Hemiptera: Aphididae) on susceptible and resistant wheat, Triticum aestivum L., near-isogenic lines 'Tugela' (susceptible), Tugela-Dn1 (antibiotic), Tugela-Dn2 (tolerant), and Tugela-Dn5 (antixenotic) was evaluated by assessing photosyn...
