“…Aphid causes indirect damage by transmitting numerous plant viruses and fungi (Aslam et al, 2005) By secreting honey dew, on which sooty mold fungus grows (Akhtar et al, 2003). The pest causes 35-40% losses by desaping and 20-80% by disease transmission (Kuroli, 2000) and is considered the most significant factor of declined yield (SD Kindler et al, 2001).…”

Aphid is a major pest of wheat that causes substantial agricultural damages to wheat crop annually. In the present study, experiments on ecofriendly management of this pest were conducted at the experimental area of Arid Zone Research Institute (AZRI), Bhakkar. The trials were laid down in Randomized Complete Block Design (RCBD) with three replications. Data was collected at seven days interval by counting method. As far as efficiency of yellow sticky traps is concerned, the plot having 4-traps captured maximum (848.07) aphids. As a result, minimum (11.16 aphid tiller-1) were observed in the respective plot. The same plot exhibited maximum population reduction (71.93%) and grain yield (6617.9 kg ha-1). The plot having 1-trap captured minimum (257.33) aphids. Consequently, maximum (33.37 aphids/tiller) were found in the field. The same treatment showed minimum population reduction (23.99%) and grain yield (5489.1 kg ha-1). Chrysoperla carnea was found a voracious predator of the pest. The plot having 4-egg cards of this predator showed minimum (7.69 aphids tiller-1) with maximum (49.50%) population reduction of the aphid followed by 8.78 aphids/tiller in the plot having 3-egg cards with 42.56% population reduction. Lowest population reduction (12.33%) was found in the plot having 1 egg card.

“…Aphid species infesting wheat cultivars which considered as the most dangerous and significant sucking insect pest infesting various crops with significant damage shown as distortion, chlorosis, curling of leaves and afterwards affect the growth (Dedryver et al, 2010;Akhter and Khaliq, 2003;Kindler et al, 1995). It has been recorded that there are 29 species of aphids are known with their ability in infesting wheat cultivars (Geza, 2000). The most common species are bird cherry oat aphid: Rhopalosiphum padi (L.); English grain aphid: Sitobion avenae (Fabricius); the greenbug: Schizaphis graminum (Rondani); Russian wheat aphid:…”

The study was conducted during (2015/2016 and 2016/2017) on bread wheat cultivars: Sahel1, Seds4, Gemaza9, Giza168, and Misr2 in Plant Protec. Dept. farm, Fac. of Agric., Assiut Univ., Assiut, Egypt to determine the separate effect of some abiotic and biotic factors on the population dynamics of aphid species: Mayzus persicae; Brivecoryne brassicae; Rhopalosiphum padi, and onion thrips, Thrips tabaci Lindeman under drought and irrigation conditions. The considered abiotic factors: plant age, chlorophyll AB; climatic factors: Daily Maximum Temperature (DMxT), Daily Minimum Temperature (DMnT), Soil Daily Maximum Temperature (SMxT) and Soil Minimum Temperature (SMnT) at 3 to 5 cm depth from soil surface, beside the biotic factors which presented in natural enemies (N.E.) to clarify which cultivar is suitable to be planted under drought or irrigation conditions under free insecticides use for both pests with references to cultivars yields. The infestations of both pests started in February during 1st season and January for 2nd season in all replicates with a high mean numbers of pests on cultivars under irrigation conditions than drought conditions. The peaks of aphids recorded from the middle of the 2nd month to the 3rd month; and thrips in the 2nd month to the half of 3rd month from sampling date under both conditions. The most important factors regulated the fluctuation of pests under drought conditions were arranged according to their efficiency as (DMnT= 26.70), (DMxT= 16.91), and (N.E= 16.40); respectively out of (66.50 %). Under irrigation conditions, fluctuations were determined by the efficiency of (N.E.= 38.17), (Chlorophyll AB= 14.97), and plant age (9.96); respectively out of (83.19 %) with positive significant correlations on all selected cultivars. Top yields were gained from Giza186, Misr2, and Sahel1; respectively during seasons of the study under both conditions, except Gemeza9 under irrigation condition in 1st season ranked the 3rd yield.

“…Indirect damage is caused through stunting and premature plant death, reduction in photosynthesis, as well as sterilization of inflorescences, plentiful honeydew production, which may result in deformed leaves, and growth of sooty mold (Blackman & Eastop, 2000). Among economic pests, 29 aphid species infest wheat crops (Kuroli, 2000). Predominant species are the greenbug, Schizaphis graminum (Rondani) and bird cherry oat aphid, Rhopalosiphum padi (L.) (Bosque-Perez & Schotzko, 2000).…”

Field assessment of neonicotinoids against three aphid species and their natural enemies on wheat crop in Ismailia, egypt

Aphids are the most important pests on wheat in Egypt and worldwide. Field trials were conducted to assess the efficacy of the neonicotinoid insecticides imidacloprid (Nufidor 60% FS; at the doses of 2. 1, 1.05 and 0.525 g a.i./kg of seeds) and thiamethoxam (Cruiser 70% WS; at the rates of 14.4, 7.2 and 3.6 g a.i./kg of seeds) as seed treatments, and thiamethoxam (Actara 25% WG; at the rates of 0. 1, 0.05 and 0.025 g a.i./l) as foliar application, against three wheat aphids: bird cherry oat aphid, Rhopalosiphum padi (L.), greenbug, Schizaphis graminum (Rondani), and corn leaf aphid, Rhopalosiphum maidis (Fitch). Their effects on the aphids' natural enemies: lacewings, Chrysoperla carnea Stephens, ladybird beetles, Coccinella spp., and syrphid flies Syrphus spp. were assessed as well. The trials were conducted on the farm of the Faculty of Agriculture, Suez Canal University, Ismailia Governorate, during 2013/14 and 2014/15 seasons. Our results showed significant differences between the tested insecticides at all concentrations and clearly indicated that the recommended doses of all insecticides were more efficient against aphids on wheat plants than half-and quarter-doses. Also, the data revealed significant differences between the two seed treatments at all doses before and after foliar application, as compared to the control at all time intervals of inspection regarding the mean number of aphids on wheat plants, from the 3 rd until 13 th week after sowing, except in the 8 th week after seed treatment before foliar application. The results clearly indicated that the weekly reduction of infestation and the general efficacy was higher at the recommended doses of Nufidor, Cruiser and Actara than the half and quarter doses in both seasons. Also, reduction in infestation decreased over the following weeks until the 8 th week, when Actara insecticide was sprayed. Data revealed that there were no significant differences between treatments and control in the mean number of Chrysoperla carnea and Syrphus spp., while a significant difference in the mean number of coccinellids was observed on wheat plants treated with imidacloprid seed treatment before foliar application 6 and 7 weeks after sowing, and also after foliar application with thiamethoxam 9, 10, 11, 12 and 13 weeks after sowing. Regarding thiamethoxam seed treatment, significant differences were revealed in the ladybird population on wheat plants 3, 4, 7 and 8 weeks before foliar application, and only in the 10 th week after spraying with thiamethoxam.
