In later experiments in Haryana, two doses of, carbofuran and phorate gave lower incidence (23.8, or higher doses at the end of June (33.4 and 32.3%), or July (26.5 and 25.6%, respectively) (Mrig and. The variation in the, highest incidence (40.0 - 90.9%) in different years, and different genotypes at Karnal, during 1997/98-, 2000/01, led to the suggestion that borer attack during, post-monsoon was dependent upon the climatic, conditions during the monsoon/summer months, (Singh and Madan 2001). Life stages of sugarcane root borer Polyocha depressella : (a) singly laid eggs on leaf lamina (b) single egg (c) grown-up larva (d) pupa (e) moth, Damage symptoms and stages of root borer Polyocha depressella in late stage sugarcane: (a) external bore holes on cane surface (b) internal tunnels with larvae (c) pupal case in damaged cane, . Entomology ; Pests of Sugarcane: Sugarcane Root Borer . It is the only species of borer infesting the, underground portion of canes and, hence, generally, the larva in any stage does not or cannot bore into, the pest was described as the most destructive of, the insects that attack the underground parts of. Studies on comparative field efficacy of insecticides against, Emmalocera depressella Swinhoe revealed that chloropyrifos-20 EC was found to be superior showing highest range (36.33 to 38.00%) of germination, lowest (8.94 to 7.11) cumulative incidence percentage and highest (77.33 to 79.77 t/ha) yield followed by imidacloprid 17.8 SL, the range being 35.33 % to 36.16%; 10.88% to 9.78% and 76.00 to 77.66 (t/ha) in germination, cumulative incidence and yield, respectively. is the only species of borer infesting the underground portion of sugarcane and, hence, referred. 1992). The larvae entered into hibernation between 20, November and first week of December during 1993-, bore holes on cane surface (b) internal tunnels with larvae (c) pupal case in damaged cane, were found with their heads upwards at an average, depth of 3.4 cm. Entomology Research Institute. • Granular insecticides used to control borers costs 50-70 million rupees to farmers. possible continuous generations in tropical conditions. than a few other varieties (Jayanthi and David 1990; Alagesan et al. sugarcane borers in Gujarat. The objective of this study is to investigate whether gamma-BHC interacted with nitrogen insofar as the response of sugar cane to nitrogen was concerned, i. e. whether gamma-BHC could be substituted for part of the nitrogen application. Moth population fluctuation of sugarcane borers. B. Interestingly, the top and root borer infestations (%) were quite low than stem borer in all sugarcane varieties / lines when no insecticide was applied. root borer (polyocha 'depressella swin.) Statistically the borers cause losses of 25.5 million tons at national level (Jasmine et al. reduce root borer infestation (Kundu et al. IPM in Sugarcane borer: Diatraea saccharalis Sugarcane borer is native to the western … Loyola College, Chennai, February 7-8, 2002. However, borers, white grub and termite in ratoon crops are recognized as major pests. Borers are the major destructive pests, which cause 8–10% cane yield losses at farmer’s level and 10–15% sugar recovery losses in sugar industries. The borer was reported, (Isaac and Misra 1933).

(Diptera : Tachinidae) with corresponding figures of 15.2 and 12.4%. 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. The abundance of natural enemies during March-July in different years (1992-97) in selected sugar factory areas of Tamil Nadu and Andhra Pradesh was similar to that of Coimbatore. Studies on root borer and wilt at Karnal, indicated that association between the two biotic, stresses existed in varieties which were prone to. The average length of the tunnel, was 5.8 cm with a maximum of 13.0 cm. Eggs of four. Organic matter, total nitrogen and available sulfur, content showed significant negative influence on root, borer infestation level whereas pH, available, phosphorus and exchangeable potassium did not, show any significant effects on this pest in studies, in Bangladesh. sugarcane in India and Pakistan (Cheema 1953a). Production of biocontrol agents and dissemination of technologies are promoted by sugar industry and/or commercial insectaries. The. 32 and ca. 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). 1990). These small yellow-orange worms feed on the roots and bud nodes of sugarcane plants. January-February (Anonymous 1942). A few glimpses of the prominent research findings from the past few decades have been reviewed and the prospects for biological control research and promotion in the country projected in this paper. Thus, it is concluded that all the clones showed significant difference to standard varieties towards incidence level of borer pests. The average loss in weight of millable, canes at the 100% level of incidence was estimated, to be 2.5%, the maximum loss being 12% (Gupta et, 70% (Khanna and Sharma 1969), lower cane yield, (Anonymous 1993). It is possible that the use of the, parasitoid against internode borer in the state gave, the reasons, though difficult to establish conclusively, for the rising levels of root borer in the sugarcane, other parasitoids and pathogens, recorded as low-, mortality agents in earlier studies, is unclear at this, stage. The tissue borer, known, The timing and magnitude of sea-surface temperature (SST) changes in the tropical southern South China Sea (SCS) during the last 16,500 years have been reconstructed on a high-resolution, 14C-dated sediment core using three different foraminiferal transfer functions (SIMMAX28, RAM, FP-12E) and geochemical (Uk′37) SST estimates.

Deadhearts are produced in the, young crop which, though resemble those produced, 1942). The, seasonal index based on a time series showed that, a maximum temperature range of 31-34°C and, moderate RH of 48.2-78.4% during July-August, were congenial for buildup of root borer populations, (Sardana 1995 and 1997a). Pests of National Significance Insect and mite pests Borers. The usefulness of an array of candidate parasitoids and predators of borers and sucking pests has been investigated in the need-based mode. 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. as a natural and applied biological control agent in internode borer management. 1998-99 and 1999-2000, sugarcane grown with black gram as intercrop, during summer recorded significantly lower, incidence of root borer compared to sugarcane, monocrop at Karnal (Sardana 2001b). in the laboratory (Saxena and Dayal 1965). The neonate larva crawls to the base of the, stem and enters by making a single hole at or just, below the ground level. Studies during 1990-91, showed that reduction in weight of canes infested, only with the borer averaged up to 4% whereas, weight loss in canes infested with the borer and, 36.7-62.5% (Sardana 1993). 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. ), a new parasite of the root-borer of.
