Field experiments were conducted at three locations for two seasons, 2018 to 2020 to evaluate the efficacy of soil insecticides against sucking pests of potato. Lowest cumulative mean number of whiteflies was observed with fipronil 0.3G @ 25 kg/ ha, and it was on par with its dose of 20 kg/ ha, cartap hydrochloride 4G @ 20 and @ 25 kg/ ha; overall reduction in whiteflies over control ranged between 56.70 and 59.04% at Jalandhar; 53.17 to 60.89% at Modipuram, and 57.33 to 62.40% at Gwalior. Similar trends were noted for aphids, leaf hoppers and thrips. Based on tuber yield and benefit cost ratio, cartap hydrochloride 4G @ 20 kg/ ha (2.62) and fipronil 0.3G @ 20 kg/ ha (2.47) were found to be the most effective against the sucking pests of potato. Hence, both these can be recommended in potato in place of phorate 10G.

Potato aphid Macrosiphum euphorbiae(Thomas) (Hemiptera: Aphididae) is colonizing species and vector for many economically important potato viruses. There is dearth of genomic information about this economically important aphid species. Hence, to get insight into the genomic architecture, genome size was determined using flow cytometry. The estimated size of M. euphorbiae was 0.53 pg or 519.4 Mbp. The genome size of M. euphorbiae is approximately 2.9, 2.2 and 1.9x larger than that of Drosophila melanogaster, honey bee (Apis mellifera) and mosquito Anopheles gambiae, respectively. The generated genome size information will provide the foundation for futuristic genomic research on M. euphorbiae.
