Crop Res (Hisar) 8(2):354-362. Indian J agric Sci, Rahman KA and Singh D (1942) Studies on deadhearts, for the management of sugarcane pests in tropical, India – an advisory for intelligent use. Following first adult, emergence in March and oviposition soon after, the monsoon months but increased again soon after, the rains. The possibility of variety-dependent (Pandya et al. The list of major (that cause economic damage to this crop) insects pests of sugarcane are given below, 1. While, the pre-oviposition, oviposition and post-oviposition, periods ranged 1 - 3 d each, total life period from. In a subsequent report (Anonymous, 1993), variable infestation levels were recorded in, The surge in the root borer incidence, observed by, the present authors in the sugarcane tracts of T. Nadu during 2014-15 (R. Jayanthi et al. borer infestation. insecticide treated plots. Density-independent (weather) factors showed inconsistent relationships with shoot borer and its natural enemies in the two years. observed to provide a low degree of biological control, failed to parasitize root borer when various borer. After hatching the larvae bore into the midrib and tunnel towards the stem for 24-48 hours and then enter the stem. The masses are slightly overlapping like tiles. These small yellow-orange worms feed on the roots and bud nodes of sugarcane plants. 3 genotypes (Co 1148, S 85/314 and S 85/94) were graded as highly susceptible, as the larval population and corresponding incidence were highest in these varieties'. Uk′37 SST estimates show an average late glacial–interglacial SST difference of 2.0°C, whereas the RAM and SIMMAX28 foraminiferal transfer functions show only a minor (0.6°C) or no consistent late glacial–interglacial SST change, respectively. The timing of expanded ice cover in the central Peruvian Andes correlates broadly with the timing of massive iceberg discharge (Heinrich) events in the North Atlantic Ocean, suggesting a possible causal connection between southward migration of the Intertropical Convergence Zone during Heinrich events and a resultant increase in precipitation in the tropical Andes. In a Nutshell. The stable crop habitat and minimal pesticide usage accord a prominent role for biological control. to root borer in sugarcane. Seasonal fluctuations of natural enemies of sugarcane shoot borer Chilo infuscatellus Snellen (Lepidoptera: Crarnbidae) were examined at Coimbatore, Tamii Nadu, India, during 1995-97. Narrow. Global Lepidoptera Names Index (LepIndex). While root borer infestation in wilted. Besides, Gotterell (1954) reported it from, Malaysia and Bangladesh, besides Pakistan, in its, In India, it occurs on sugarcane in the north Indian. usually three parasitoids per egg (Pruthi 1936). Fletcher TB (1932) Report of the Imperial Entomologist. In light trap studies, in Pakistan, root borer populations peaked during, Light trap monitoring studies at Coimbatore showed, low moth catches in two different years which, indicated negligible pest occurrence in the area. A key for the identification of sixty-two Oriental species, based on females, is given. Incidence due to infestation by stalk borer was observed which ranged from 2.32 to 9.77% on stalk basis. In the second study, the two juice quality parameters Brix and sucrose% were significantly higher in the attacked canes. Sugarcane, (Saccharum officinarum), perennial grass of the family Poaceae, primarily cultivated for its juice from which sugar is processed. Top borer infestation was observed to be highest (23.44%) in U.P.-01104 followed by COSE-02235 (18.99%) and U.P.-01105 (17.22%) which showed highly significant difference to standard varieties. Kairomonal principles derived from borers and sugarcane as attractants to the larval parasitoid Cotesia flavipes (Cameron) were examined. In Gujarat, release of, harvest at an interval of 10 days gave encouraging, results in reducing the incidence of borers including, control programme kept three borers including root, borer below economic threshold levels in Pakistan, the host lasted 22-25 d and pupal period 10 d during. 1996a) and wilt-exacerbated (Sardana 1993) losses, Basic information on field biology and population, dynamics is required to understand the number of, generations and the consequent damage potential, in different seasons. the tunnel to ensure easy emergence of the adult.

Among the biotic stresses that afflict sugarcane, insect pests occupy a good second position behind diseases in India. Root borer populations sustained, by other susceptible varieties grown as isolated, sugarcane islands may have served as the inoculum, for the spread and adaptability of the pest to the.

Sugarcane stem borer (Chilo terrenellus) is a stem boring insect which is a serious pest of sugarcane.Sugarcane stem borer caterpillars damage sugarcane plants by boring or tunnelling inside their plant stems (Figure 1). received less attention. Granulosis virus alone acted in a density-dependent manner showing a significant correlation with shoot borer incidence (r = 0.612; P < 0.01) in the second year, which probably resulted in the slightly lower borer incidence in this study year. In shoot borer infestation, incidence ranged from 6.66 to 15.10%. In this paper, the work carried out on root borer in subtropical, sugarcane belt of the country is reviewed and notes, on its occurrence in the southern states are, presented. The incidence of the, applied twice, i.e. in the laboratory (Saxena and Dayal 1965).

After hatching eggs larvae bore into the roots or underground portion of the stem. Mass multiplication and field evaluation that began in the early decades continue today, as is demonstrated by the use of the most exploited parasitoid Trichogramma chilonis.

It is video about Solar irrigation pump and sugarcane field.In this video we identifi root borer disease in sugarcane and tell its solution. Infection, by pathogens, predation, irrigation and mechanical, injury of stalks caused larval mortality (Sardana, root borer passes through four overlapping, evening hours. B.

The present project intends to investigate the prospects of Telenomus sp. In a six year (1989-90 to 1994-95) study in southern, Gujarat, a highly significant positive correlation, between root borer and disease incidence was, observed in wilt affected farmers’ fields with Chi, square values of 34.02 – 55.00 and coefficient of, correlation of 0.50 - 0.60 in different years (Pandya, et al. 2000). The incidence varied from 1.0% (January, - March) to 17.1% (November) during 1998-99 and, from 0.7% (April) to 12.1% (November) during, In a six year (1989-94) study on population dynamics. Reporting the occurrence of the borer, from the same sugar mill area at about the same, 30% of clumps in a ratoon crop were infested as a, result of which one or two of the 4-5 tillers/clump, became millable but the rest dried up; also, infestation, was more common in Co 8021 and Co 7704 than, of south India, Jayanthi and David (1990) observed, that in Karnataka, the large-scale occurrence during, 1989 in Bhadravati area of M/s Mysore Paper Mills, was restricted to Co 8021 alone with attack in 15%, show borer attack which indicated varietal, preference.

Polyocha depressella Swinhoe (=Emmalocera depressella (Swinhoe)) (Lepidoptera: Pyralidae) is the only species of borer infesting the underground portion of sugarcane and, hence, referred to by its common name root borer or rootstock borer. March, May-June and September-October in a, year (Pandya et al. Sardana (2000) stated that, by adopting various techniques like flooding of fields, use of light traps, application of imidacloprid insecticide and release of biological control agent (Trichogramma chilonis ) effectively managed root borer in sugarcane. Incubation period was 4.26 - 7.86 d with an average, instars and the duration of the total larval period, was 27.0 - 39.8 d. The duration of the pupal period, was 7.41 - 10.74 d.

Studies on root borer and wilt at Karnal, indicated that association between the two biotic, stresses existed in varieties which were prone to. Fore wing pink in colour and hind wing white. In south Gujarat, root borer, yield by 6.93-20.65, 2.50-25.47, 0.72-2.75, 3.16-34.20, and 4.62-4.83%, respectively in the varieties CoC, 671, Co 8338, Co 6806, Co 6304 and Co 62175, (Pandya et al. 2012b).
