Anonymous (1942) Short notes and exhibits. In Haryana, the population remained low during May-June and, peaked during July-October (Sardana 1995 and, 1997a).

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. • Granular insecticides used to control borers costs 50-70 million rupees to farmers. Out of 26 genotypes screened against root borer (Emmalocera depressella, Swinhoe), 5 genotypes (CoH-84, CoH 89, CoH 56, S 87/15 and S 87/256) were categorized as moderately resistance. Suitable crop rotation should be followed. 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. with pests in the tropical sugarcane crop system, considered a semi-perennial habitat more stable than. sugarcane borers. projects/lepindex/search/detail.dsml [accessed on.

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. during the years of study was 18.35% (Bhatt et al. In field, Bengal, there was no initial egg parasitism of root, 28.68% in October in release plots as compared, with 5.5 and 0%, respectively in the controls; in stem, borers, parasitism levels increased in both release, and control plots.

Maximum number of eggs was laid, at 27°C. The deadheart does not emit any offensive, smell and often one or two leaves adjacent to the, central leaf whorl also dry up. Biocontrol research of the early 1930s and 40s was characterized by surveys focusing on identification and studies on the basic biology of natural enemies. 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. The average yield from the release, plots was almost a third greater than that from the, controls (Pruthi 1946). A rational pest management module including minimum quantity of synthetic organic pesticide (rynaxypyr), a semi-synthetic pesticide (cartap hydrochloride), a plant fraction (neem oil), repellent crops (coriander and basil), physical barrier, refuge planting, detrashing, removal of water and late shoots, pheromone traps, Beauveria spore formulation etc. 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.

Insect pests constitute a major biotic stress in sugarcane in India as they attack the crop from the time of planting until almost harvest, inflicting yield and sugar losses. To assess the impact of such transient aphid populations on the crop, yield and juice quality parameters, marked canes from crop patches attacked during the grand growth period were examined at harvest with unattacked canes as control. 1990) stages of the, crop might favour overlapping generations and, round-the-year activity just as shoot borer (Srikanth, et al.

Root borer of sugarcane is known as Emmalocera depressella (Swinhoe) and belongs to the family Pyralidae and order Lepidoptera. 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).

These isolates hold promise against white grub when delivered in the form of formulations, besides the long-term possibility of deploying transgenics with cry genes.
