Dynamics of insect pests play a crucial role in understanding their occurrence on a crop. Many insect pests infest on drumstick at various phenophase of the crop and limit the productivity. In the present study, the current scenario of insect pest as well as beneficial arthropods associated with drumstick was assessed and developed appropriate management strategies for major pests. The arthropods found on drumstick was leaf eating caterpillar (Noorda blitealis), aphids (Aphis craccivora), tea mosquito bug (Helopeltis antonii), bihary hairy caterpillar (Spilosoma obliqua), stem borer (Batocera rubus Batocera) and pod fly (Gitona distigma).The beneficial insects include coccinellid beetles, Cocinella septmpunctata Linnaeus, spiders: Oxyopes shweta Tikader (Oxyopidae), Thomisus spp (Thomisidae), Nescona sp and braconid wasp, Disophrys sp.; pollinators such aslittle bee-Apis florea Fab. and bumble bee, Bombus sp were recorded on drumstick. The information generated in the study would help in initiating the appropriate pest management strategies at right time to minimize  pesticide residue on the crop.Â

Inconel 600, a Ni-based alloy was considered as a possible replacement for austenitic stainless steels for service at high temperatures in nitrogen containing atmosphere of the neutron detector. To obtain a fundamental understanding of the differences in the diffusivity of nitrogen in pure Fe and Ni lattices, molecular dynamics simulations were carried out. Based on the simulation of nitrogen trajectories in the temperature range of 1200–1400 K, pre-exponential factor, activation energy and jumping frequency were calculated and compared for fcc Ni and Fe. MD simulations confirmed that rate of diffusion of nitrogen is lower in Ni when compared to Fe, suggesting the replacement of austenitic steel with Inconel 600 for better performance of the detectors.
