TL;DR: The number of setae on the first tarsal segments, the number of caudal setae, the presence of abdominal marginal tubercles on abdominal segments 2 to 4, and the size of the cells of the siphuncular reticulation allow the new species to be distinguished from other Palaeartic species of the subgenus Uromelan.
Abstract: Uroleucon (Uromelan) helichrysi sp. n. (Hemiptera, Aphididae, Aphidinae: Macrosiphini) is established from Iranian apterous and alate viviparous females caught on Helichrysum sp. (Asteraceae) and preserved in the collection of the Natural History Museum (BMNH) in London. The number of setae on the first tarsal segments (5), the number of caudal setae (20 to 28), the presence of abdominal marginal tubercles on abdominal segments 2 to 4, and the size of the cells of the siphuncular reticulation (relatively small) allow the new species to be distinguished from other Palaeartic species of the subgenus Uromelan. Blackman and Eastop’s key to apterae on Helichrysum is modified to include the new species. urn:lsid:zoobank.org:pub:E2B89D59-05FD-4A9E-AD78-B3C302219A10

TL;DR: Studies on bio-efficacy of six insecticides against safflower aphids showed that dimethoate 0.03 percent and imidacloprid 0.004 per cent were the most effective treatments for the control of saff Lower aphids.
Abstract: Studies on bio-efficacy of six insecticides against safflower aphids (Uroleucon compositae theobald) showed that dimethoate 0.03 percent and imidacloprid 0.004 per cent were the most effective treatments for the control of safflower aphids. Highest yield of safflower was recorded in dimethoate 0.03 percent but highest incremental cost benefit ratio was recorded through the application of imidacloprid 0.004 percent followed by dimethoate 0.03 per cent.

TL;DR: Subspecies Dysaphis pavlovskiana indica Chakrabarti & Medda, 1993 is given species status and the nomen nudum Uroleucon (Uromelan) lehri Zaitzev, Lelej, Storozhenko & Kurzenko, 2006 is recognized as referring to Urole urogynous campanulae (Kaltenbach, 1843).
Abstract: Subspecies Dysaphis pavlovskiana indica Chakrabarti & Medda, 1993 is given species status (Dysaphis indica Chakrabarti & Medda, 1993, new status). Aphis plantaginis asiatica Daniyarova, 1979 is a synonym of Aphis taraxacicola (Borner, 1940). The nomen nudum Uroleucon (Uromelan) lehri Zaitzev, Lelej, Storozhenko & Kurzenko, 2006 is recognized as referring to Uroleucon (Uromelan) campanulae (Kaltenbach, 1843).
