Millet-A Brief Review on its's Insect pests and Their Management strategies in Idian Continent
Millets are known as the oldest nutri-cereals to human being. Millets are attacked both in field and storage conditions by more than a hundred insect pests out of which some are widespread in millet-growing regions. Incidence of the insect pests on millet is region as well as season specific. In Indian subcontinent, insects belonging to lepidoptera, coleopteran, diptera are more significantly abundant in millet growing areas as regular and sporadic pests. Among these, white grub, stem borers, shoot flies and some sucking insects are most significant at different growth stages of the crop. Also, incidences of armyworms, grasshoppers, chinch bugs, leaf beetles, head caterpillars, and head bugs are responsible for significant yield losses. During the rainy season, storage bugs are more common. There is a need for more in-depth research on the incidence and management of major insect pests of millet in relation to climate change. The management strategies vary depending on the agro ecosystem and the pest complex. However, a combination of cultural practices and resistant cultivars has proven effective. In order to minimise the usage of insecticides, which are frequently used in pest endemic areas and during outbreaks, an integrated approach to pest management in millets can be provided with a thorough study on insect pests of millets and reviewing all established management strategies and incorporating the interchange of genetic material and research data.
Standardization of new screening method and evaluation of soybean (Glycine max (L.) Merrill) genotypes for seedling stage drought tolerance under in-vitro conditions
Drought is one of the most important constraint in realizing potential yields in soybean crop. Screening of germplasm lines for drought tolerance is hindered by the lack of rapid, reliable and stable phenotyping technique. In-vitro screening technique in soybean based on seedling survivability and drought score was standardized and the method was employed to screen 70 diverse soybean genotypes for seedling stage drought tolerance. Drought treatment was imposed at third unrolled leaf stage (V3 stage) by exposing seedlings roots to open air on a hydroponics set up under controlled conditions. At the end of screening period the seedlings were scored for seedling survivability percentage and drought score on a 0-4 scale based on seedlings shoot and root traits. The genotypes ‘HIMSO 1587’, ‘SL 46’ and ‘TGX1835-3E’ were identified as highly tolerant under in-vitro screening conditions. The tolerant lines recorded longer root and shoots, higher fresh and dry weights of roots and shoots than the susceptible lines. The contrasting phenotypes were once again screened in two soil culture techniques (seedling recovery and seedling non-recovery) and the results obtained were in compliance with in-vitro screening results. The new method developed is rapid, easy and cost effective in identifying tolerant and susceptible lines effectively at seedling stage and therefore can be utilized in identification of novel drought tolerant lines through screening of large number germplasm lines.
MANIPULATION OF CROP MICRO-ENVIRONMENT FOR ENHANCED LIGHT INTERCEPTION AND HEAT UNIT ACCUMULATION IN SALI RICE IN ASSAM
A field experiment was conducted in 2016 and 2017 to study the manipulated crop micro-environment on effective light interception and heat-unit accumulation for improving sali rice production. The trial was comprised of two crop establishments, viz. system of rice intensification (SRI) and conventional rice cultivation (CRC); three transplanting dates (26thJune, 10thJuly, and 25th July) and four crop geometries (20cm x 15cm; 20cm x 20cm; 25cm x 20cm and 25cm x25cm) laid in factorial split-plot with three replications. Results revealed that the SRI crops took lesser days to attain maximum tillering, 50% flowering, and physiological maturity as compared to CRC. In spite of lesser accumulated growing degree-days (GDD), helio-thermal unit (HTU), photo-thermal unit (PTU), and light transmission ratio (LTR); the SRI establishment gave maximum grain yield. The superiority of early crops was observed in effective utilization of solar energy for grain formation. The widely spaced crops showed significantly inferior LTR with increased grain yield. Further, a significantly strong negative association was observed with LTR (-0.82**) during the vegetative phase of SRI crops. The regression model revealed that the vegetative phase of sali rice was the most critical phase in terms of higher radiation interception and dry matter production.
Development and population growth parameters of invasive leafminer, Tuta absoluta (Lepidoptera: Gelechiidae) and serpentine leafminer, Liriomyza trifolii (Diptera: Agromyzidae) on tomato crop under different farming systems
The tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) and the serpentine leafminer, Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) are devastating pests of tomato. We study the effect of tomato grown under zero-budget natural farming (ZBNF), organic farming (OF) and conventional farming (CF) systems on the development biology and population growth parameters of these pests. Tomato grown under different farming systems had significant effect on the biological parameters like incubation period, pupal period and fecundity of T. absoluta and L. trifolii. Population growth parameters like gross reproductive rate, net reproductive rate, intrinsic rate of increase, doubling time and finite rate of increase was also calculated. These results showed no significant differences had found on these parameters when T. absoluta and L. trifolii were reared on tomato grown under ZBNF, OF and CF systems. These findings can be useful for developing and improving sustainable management of the pest.
Immunoassay of cow, buffalo and goat oviductal proteins indicate antigenic similarities among the species
Identification of antigenic similarities in oviductal proteins among cattle, buffalo and goat. Buffalo oviductal proteins were isolated and hyper immune sera was raised in rabbits against buffalo oviductal proteins. Double immuno diffusion (DID) was used to detect homologous protein in the oviductal secretions of cow, buffalo and goat. For detection of immunologically homologous proteins in oviductal proteins enzyme linked immuno electro transfer blot was done. Results of DID indicated identical oviductal proteins among cow, buffalo and goat. At least one oviductal protein (molecular weight of 60 kDa) was similar among cow, buffalo and goat. A 70 kDa protein was observed in goat oviductal proteins, which was absent in cattle and buffalo oviductal fluid. It was inferred that cattle, buffalo and goat share homologous oviductal proteins, indicating the possibility of using oviductal proteins from buffalo to modulate the functions of cattle and goat spermatozoa. However, the functional analysis of the homologus proteins needs to be elucidated.
