root borer of sugarcane

Written by . Posted in Uncategorized

After hatching the larvae bore into the midrib and tunnel towards the stem for 24-48 hours and then enter the stem. ;] 20EC also reduced incidence. Trichogrammatidae (Hymenoptera: Chalcidoidea). Louisiana sugarcane (Saccharum spp.) 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. The possibility of variety-dependent (Pandya et al. • Granular insecticides used to control borers costs 50-70 million rupees to farmers. Adults are pale pink in color. to be adopted in tropical India are outlined. borer attacks sugarcane in the early stages (Pruthi, 1937) when the crop is 2-4 months old and, Anonymous 1943). Natural parasitism in sugarcane root borer, Box HE (1953) List of sugarcane insects. STUDIES ON THE INTERACTION BETWEEN GAMMA-BHC AND NITROGEN APPLICATION IN SUGAR CANE. predominant Co 86032 over the last two decades. 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. 65, ca. 21 ka) suggests that if an advance culminated at that time any resulting moraines were subsequently overridden. During, fields, where the adults were seen in small numbers, varied from 3 to 5% (Narayanan 1938). Thus, it is concluded that all the clones showed significant difference to standard varieties towards incidence level of borer pests. Insect Science and its, Srikanth J, Easwaramoorthy S, Santhalakshmi G (2001), Seasonal fluctuations of natural enemies of, Srikanth J, Geetha N, Kurup NK, Santhalakshmi G (2002), Density-dependent natural control of sugarcane. 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. 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. native borer complex (Isaac 1941; Pruthi 1946; Ashraf and Fatima 1996) suggested indirect impact, of the parasitoid. 1990). The systematic position of the genus in the higher classification of the family is briefly discussed, and tentative species-groups are outlined. Despite its more or less pan India, distribution, much of the earlier work was restricted, to the north Indian sugarcane belt due to its persistent, occurrence and more serious damage. Breeding Institute (ICAR), Coimbatore, India, 396p. It is recorded from American Samoa, Australia, Cook Islands, Federated States of Micronesia, Fiji, French Polynesia, Guam, Marshall Islands,New Caledonia, New Zealand, Niue, Northern Mariana Islands, Papua New Guinea, Samoa, Solomon Islands, Tonga, and Vanuatu. Early shoot borer: Chilo infuscatellus (Crambidae: Lepidoptera) Distribution and status: India, Pakistan, Indonesia, Thiawan, Philippines, Korea, Afghanistan and Burma. In two-year field experiments in Pakistan, the linear, association between cane height and root borer, population was not significant though the borer, together with two other borer species, contributed, to 36% variation in cane height (Ansari and, contained more sucrose than uninfested ones in one, year but the weight of infested canes was less than, that of the uninfested ones and the sucrose content, was greater only in some test varieties (Pruthi and, Narayanan 1939). 1992; Jayanthi and Salin 1993). The fungus Beauveria brongniartii (Saccardo) Petch attained commercial production against the white grub Holotrichia serrata F. following its successful evaluation in elaborate trials. While root borer infestation in wilted. Comparative analysis of the results from the study with yield loss assessments made in the pre-parasitoid introduction period indicated that the parasitoid, which controls the abundance and spread of aphid populations in a short span of time, eventually prevents economic loss to the crop. The activity of natural enemies did not show significant correlation with different climatic factors. B. Larval period is 25-40 days. The borer was observed, throughout the year in extensive surveys carried out, in Gujarat during 1992-1995 (Pandya et al. 2012). In Uttar Pradesh, sugarcane over a decade averaged 23.9% (Gupta, generation killed all shoots attacked but those of the, last generation had no apparent effect on the weight, generations reduced cane length by 66.2, 14.3 and. Full grown larva is 25-30 mm long dull creamy white having shorter legs. Krishidarshan Bengaluru - 26/4/2018 at 6pm. Entomology Research Institute. the academic encouragement and logistic support.
