These results are in accordance with the works done by. 21 The seasonal variations in turmeric growth, detailed soil nutrient profile rhizosphere microorganisms, phytomorphological and phytochemical natures were studied by.22 The fluctuations in the amount of leaf damage were observed in all the treatments and the levels varied throughout the treatments (Table 2). The minimum damage may be caused by first and second instar larvae because the larvae are too small and feed less than the fourth
and fifth instar larvae which are voracious eaters and cause maximum damage within few days. The stage of the host plays an important role in the success of entomopathogenic fungi. As this experiment is concerned, the weaker stages are the second, third and fourth instar larvae as the fifth instar larvae were more tolerant to the fungal attack. In the present study, observations on various physiological parameters indicated that Temozolomide the biocontrol treated plants are physiologically more active compared to that of the untreated control plants. All the biochemical constituents were superior quantitatively Gefitinib molecular weight in biocontrol treated plants to untreated plot (Fig. 2). In general, when the plants are physiologically active, biochemical constituents are synthesized in larger amount which have resulted an increase in rhizome yield. Among the important biochemical constituents, amino acids, polyphenols and catechin
have direct influence on the quality and quantity of rhizomes. The secondary metabolite produced by the fungi affects the growth and development of other organisms. Among the major compounds present in H. citriformis 1,2-benzene dicarboxylic acid 4-nitro, and 1,2-benzene dicarboxylic acid 4-nitro, butyl octyl ester are present abundantly with a peak area of 31.53 and 40.36; respectively ( Table 4). Various substituted thiophenes constitute the important class of heterocycles and have been reported to possess found a variety of biological and pharmacological activities such as anti-fungal, antibacterial, antiviral, insecticidal, antihypertensive,
anticoagulant, analgesic and anti inflammatory properties. 23 Phthalic acid, being one of the three isomers of benzene dicarboxylic acid has proved evidence as insecticide, pesticide and larvicide activity. 24 Natural predators of U. folus namely Trichogramma spp. and bracanoids were also recorded in the test plots which implies that the biopesticide applied in the treatments do not harm them. The results of the present study showed that the H. citriformis has potential value to be stated as a good substitute for synthetic pesticides in pest management. Even though the results of this study gives first and foremost solid proof for the use of H. citriformis, extensive research on the appropriate concentration/dose and spraying schedules in field need to be further worked out for effective management of the pest. It is inferred from these findings that H.
