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

Paper ID- AMA-05-08-2023-12492

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

Paper ID- AMA-04-08-2023-12491

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.

Prediction of Total Milk Yield on the Basis of Monthly, Cumulative Monthly Milk Yield and Peak Yield in Sahiwal Cows

Paper ID- AMA-04-08-2023-12490

The coefficient of determination (R2) value estimates showed an increasing trend from the first month (28.40%) of lactation to the third month (77.37%) and then declined gradually reaching lowest (11.84%) for the tenth individual monthly yield. The rate of increase was maximum during the early part of lactation. Similarly, the rate of decline was also maximum at the later stage of lactation. In the middle of lactation i.e. second, third, fourth, fifth and sixth month of lactation the coefficient of determination (R2) value was more or less similar. The error was minimum for the prediction based on individual third month milk yield and maximum for individual tenth month milk yield. The individual monthly yields in the middle part of lactations i.e. second, third, fourth, fifth and sixth months showed comparatively better accuracy in prediction with minimum error estimates and hence these records may also be used for prediction of 300-day milk yield. From the above discussion it was concluded that the individual third month milk yield records gave the best prediction of 300-day milk yield among the all individual monthly yields as the error variances were lower and the R2 values were also higher.

Due to the rise in popularity of ultra-low power applications, the reduction in power dissipation has received more attention. Due to its lower power dissipation, Sub-threshold Adiabatic Logic (SAL) is a technology that can be very beneficial. This paper presents four sets proposed subtractors that have been implemented in 90nm technology utilizing CADENCE Virtuoso software and both the SAL approach and conventional CMOS logic. The proposed subtractors aim to attain lower power dissipation and count transistors while additionally considering design accuracy into account. The circuit parameters have been analyzed, and these circuits are further compared to conventional subtractors. The proposed approximate subtractor APSUB1 is 51% more efficient than the least power dissipated circuit of the recent existing circuit which is APSC6. When comparing the power dissipation using CMOS and SAL technique, there has been a power reduction of 17% for APSUB1 circuit when implemented by SAL. By employing the SAL technique, the proposed subtractors have an efficient improvement in the circuit aspects and a further reduction in the power and area of the design. Eventually useful in agricultural Control engines, because of its low-power and energy-efficient features.

A new sector for rural economic growth is the seaweed industry, particularly in coastal districts. Along the entire coast of Tamilnadu, there is a total of 5048 hectares that might be used for seaweed farming. Around 1,15,150 MT of seaweed are now in demand in Tamilnadu. However, the actual estimated production is only 13,300 MT. The seasonal availability and prevailing market price of seaweeds were studied through personal interview among 285 respondents and major traders in coastal areas of Tamilnadu to explore the potential seaweeds to be utilized as livestock feed. It was found that Sargassum wightii, Turbinaria ornata, Gracilaria verrucosa, Gracilaria edulis, and Kappaphycus alvarezii were having the potential to be utilized in livestock feeds based on availability and prevailing market price. Further research is needed to identify the nutrient composition, plant secondary metabolites and level of economic inclusion levels of these seaweeds in livestock feeding.
