“…Direct yield losses caused by bird cherry oat aphid are greatly dependent upon plant growth stage; as 24-65% losses can occur in case of infestation at seedling stage, and very low or non-significant yield losses from booting or later stages have been reported (Kieckhefer et al, 1995;Voss et al, 1997). Indirect yield losses are caused by transmitting viral diseases e.g.…”

“…Rhopalosiphum maidis (Fitch), Rhopalosiphum padi L., Sitobion miscanthi (Takahashi) and Sitobion avenae (Fabricius) (Deol et al, 1987). The aphid damage is seen during grain filling stage when both nymphs and adults take a heavy toll by sucking cell sap from leaves and maturing grains (Voss et al, 1997). The infested leaves turn pale, wilt and wear a stunted appearance and cause 3-21 per cent grain yield loss (Singh and Deol, 2003).…”

Journal of Wheat Research 9(1): 54-59. *Corresponding authorEmail: beant19@pau.edu © Society for Advancement of Wheat and Barley Research AbstractWheat is the principal cereal crop of India and every year it suffers serious grain yield losses due to insect pest and diseases. In last few years, the simultaneous attacks of aphids and stripe rust were noticed during reproductive stages of wheat growth. As such the combination of different plant protection chemicals is not recommended, but combined application saves time, labour and money by reducing the number of sprays. Thus, it becomes inevitable for farmers to think about pesticide combinations when simultaneous appearance of disease and insect are confronted in the field. The compatibility of insecticide and fungicide mixture is a matter of great concern. The investigations were conducted to test the field efficacy and compatibility of some insecticides with broad spectrum fungicide propiconazole. The results of the studies clearly indicated that combinations of propiconazole with imidacloprid and thiamethoxam did not hinder their efficacy. However, the aphid control was significantly less (0-5.95 %) when the combination of insecticide and fungicide were sprayed in 500 litres of spray volume as compared to 250 litres of spray volume per hectare. At the same time, reduction in coccinellid population was also less (2.48-8.96%) when 500 litres of spray volume was used. The information from the study will help the farmers confronted with the combined attack of stripe rust and aphids in wheat growing regions of the country. The tested combinations can reduce cost of pesticide application in wheat crop and can also fit well in IPM programme.

“…The aphids Rhopalosiphum padi L. and Schizaphis graminum (Rondani) are two of the most serious pests of wheat (Triticum aestivum L.), and can significantly reduce wheat yields by 30-40% solely due to feeding and up to 60% when such damage is combined with virus infection (Kieckhefer and Gellner 1992;Voss et al 1997;Riedell et al 2003). Both aphid species are widely distributed in regions where wheat is grown (Blackman and Eastop 2007), however, S. graminum is not a wheat pest in northern Europe.…”
