Empirically, long hours of leaf wetness and minimum temperature >5oC during the preceding 3 days also favoured the aphid infestation. In addition, the growth conditions for R. indica are less demanding than those for A. thaliana. Winter annuals require a vernalization period to … The turnip aphid is a worldwide pest, damaging mainly to crucifers. However, the aphid species having cosmopolitan distribution exhibit holocyclic and anholocyclic life cycles, both at the same time in different geographic areas.

Mustard aphid, Lipaphis erysimi, threatens the cultivation of the rapeseed-mustard (Brassica spp.) Aphid: Guide to Life cycle, Damage, Monitoring & Integrated Pest Management. Life cycle unknown; oviparae in the original description (Tissot 1932) were collected in Florida in February. Favourable weather condition The name is derived from the Latin words brevi and coryne and which loosely translates as small pipes. Most of the mortality in the treated group occurred at pupation and during pupal-adult development.

Distribution Worldwide. The insecticides used are acetamiprid 20 SP (125 g/ha) and imidachloprid 17.8 SL (150 ml/ha). Lipaphis erysimi (Kalt) is the most destructive pest. From generation of a nymph, an aphid takes 7-10 days to produce a nymph. Two larvae / mt row is considered as ETL. Diaeretiella rapae (McIntosh). It is between 1.4 and 2.4 mm (0.06 and 0.09 in) in length. The productivity of oilseed brassicas is severely affected by aphid pests. The life span both of the male and female 11-spotted ladybird beetles was recorded separately and average longevity was worked out. [5] It is found in most temperate and tropical areas of the world and feeds only on cruciferous plants. The main symptoms are curling and yellowing of leaves, and stunting.

It is extremely prolific and in warm places such as Texas, a maximum of thirty-five generations per year have been recorded. 2007). The cornicles of the cabbage aphid are relatively shorter than those of other aphids with the exception of the turnip aphid Lipap… LIFE CYCLE Insects breed pathenogenetically and female gives birth to 26 -133 nymphs they grow fast and full fed in 7-10 days About 45 generations are completed in a year. The head and thorax are black, abdomen and legs yellowish brown. Until the onset of winter, they remain in their early developmental stages, feeding on plants other than mustard. The species regulates its developmental period, fecundity and intrinsic rate of increase in response to developmental changes of the mustard plant and maintains its dispersal throughout the duration of the mustard crop. [6], This aphid is found on older leaves of brassica plants and on the roots. The cabbage aphid is difficult to distinguish from the turnip aphid (Lipaphis erysimi (Kaltenbach)). Iraq Ministry of Agriculture Bulletin 112:57 >> Lipaphis erysimi pseudobrassicae; Eastop. Conventional insecticides like malathion (0.05%) or oxy- demeton methyl (0.025%) or dimethoate (0.03%). Wingless males have occasionally been seen; these are smaller than the females and olive-green to brownish in colour. aphid, Lipaphis erysimi (Kalt.)

Lipaphis erysimi infests mustard plants and reduced yield (Singh and Sachan, 1994). infesting rapeseed-mustard crop during the rabi cropping seasons of 2009 to 2010 and 2010 to 2011. In a calendar year, up to 45 generations of aphids have been recorded. 9. on mustard cv. It is one of several species of aphid to feed on brassicas; the cabbage aphid (Brevicoryne brassicae) feeds only on these plants, while the green peach aphid is found on many crops and plants including brassicas. Winged females are able to disperse to other plants, but produce fewer offspring. 1966. Predators like coccinellids, syrphids and chrysopids; … Survival The body is faintly dusted with a white powder. Jhumka . Feeding efficiency of the six species of beetle reared on mustard aphids, Lipaphis erysimi investigated under Departmental Laboratory of Plant Protection, DBS College of Agriculture and Allied Science, Selaqui, Deharadun, Uttrakhand. About 45 generations are completed … LC 50 due to azadirachtin for L. erysimi Since they can reproduce and multiply in very short period and can cause direct or indirect effect to the production of farmers, special attention for management of this pest is necessary. The mean fecundity was 378.00 ± 26.51 eggs/female while ovipositional period, size of egg cluster, incubation period, percentage of grub emergence, larval period, pupal period, total developmental period (egg to adult), mating period and adult longevity were 4.32 ± 0.26, 9.00 ± … Lachnus tropicalis (van der Goot) (= japonicus Matsumura) Apterae are shining brownish black; BL 3.8-5.3 mm.

New record of adult males in the life cycle of Lipaphis erysimi KALTENBACH (Aphididae) from Japan . Aphid colonies on cruciferous crops consist mainly of wingless females and nymphs during most of the growing season. (1999) reported total life cycle as 24.20 and 16.02 days respectively, which is … Winged females are far less common. Hosts Mainly plants in the cabbage family, Brassica (broccoli, … Winged females are able to disperse to other plants, but produce fewer offspring. In order to understand the life parameters of Lipaphis erysimi for the eventual goal of control, the developmental periods, survival rates, lifespan, and fecundity of the species were investigated under five temperature regimes ($15^{\circ}C-35^{\circ}C$). 1974. The life cycle from egg to adult completed in 25.38 ± 1.14 and 25.75 ± 1.25 days during 2009 to 2010 and 2010 to 2011, respectively, while mean was 25.57 ± 1.20 days. and their effect on Coccinella septumpunctata was also recorded at Pilibhit (UP) during 2007-08 on Indian mustard. Feeding efficiency of the six species of beetle reared on mustard aphids, Lipaphis erysimi investigated under Departmental Laboratory of Plant Protection, DBS College of Agriculture and Allied Science, Selaqui, Deharadun, Uttrakhand. Among biological parameters such as; fecundity, fertility, and egg hatching % of a predator, seven-spotted ladybird beetle were 143, 165 and 86, respectively.

In spring an egg hatches, producing a wingless female aphid who soon begins parthenogenetically producing new wingless females. Possibly this species belongs in either Tuberolachnus or Pterochloroides . Total life cycle is 30 to 68 days. Search Advanced search. Results showed that the two-sex, age-stage life table-based net reproductive rate 1976. [6], Originally a European species, the turnip aphid is now found in most parts of the world in tropical and temperate locations. Introduction: Aphids are the sucking insect pest which are major attacking pest in vegetable crops. The average pre-reproductive, reproductive and post- reproductive period were 0.72 ± 0.84, 4.08 ± 1.03 and 0.38 ± 0.62 days, respectively. A number of insecticides have so far being recommended to control this pest but consequences of these insecticides lead to the development of resistance, resugance and do not ensure safety to non target organisms (Patel et al ., 1998; Sonkar and Desai, 1998). Oviposition and post oviposition periods were (32.0±1.45 and 2.9±0.27 days), respectively. Biologie de l'Amérique australe 2:345 >> Lipaphis erysimi pseudobrassicae; Derwesh. A. Khan and 2S. C. septempunctata, E. viridaureusand B. isaacicompleted their life cycle in 68.5± 6.5 days, 47±2 and 41±2, respectively. [3] Its common names include mustard aphid[4] and turnip aphid. Maximum temperature in the preceding week ranging 20–29oC, more so at a narrower maximum temperature range of 22–25oC as also by a morning relative humidity (RH) of >92%, favoured further when >98% and daily mean RH of >75%, cloudy weather favoured aphid build-up. 2012).
