Functional response of larval instars indicates that with increasing prey densities, the number of aphids consumed linearly increase and then become static after attain the asymptote level at certain densities were 25, 35 and 70 aphids per first, second and third instar larvae. The life table’s immature stage survival and female...

..., armyworms, apple wooly aphids, aphids, mealy bug, scales and whiteflies, and parasitic weeds are considerably affecting GB crops. These diseases and pests can jeopardize GB’s food supply if not monitored regularly. The consequences of these biotic agents range from minor symptoms to catastrophic events that destroy whole fields. Plant protection units are needed to tackle these challenges to prevent future outbreaks....

...boveground herbivores of aphids, and aboveground herbivores prevented the increase of grubs, whereas plants regulated population change through interaction with above- and below-ground herbivores, thus reducing the survival rate of above- and below-ground insect herbivores. In naturally occurring populations, behavior of leaf-feeding were influenced by root-feeders, causing multitude interactions at the same time. In conclusion, it is suggested that there may ...

...ed live host, preferably aphids. Artificial diets prepared from different sources do not prove very successful due to complexity of preparation for coccinellid beetles. Short seasonal availability of aphids hinders the rearing procedures. Therefore, some alternate natural dietary sources are essential to continue the mass rearing of ladybirds. In present study, we compared the longevity and egg laying of two species of ladyb...

Female beetle was recorded with a maximum mean number of aphids (2561) consumption as compared to male beetles (1921). Furthermore, the apparent mortality was highest at egg stage, making it the most vulnerable stage in the beetle’s life cy...

Only one band of purified virus preparation was observed 3.5 cm below the meniscus of the density gradient. Infectivity test of the viral zone was found positive. The absorption spectrum of the purified virus isolate had a maximum at 262 nm and a minimum at 251 nm. The max/min and A260/280 ratios of the virus isolate were 1.83 and 2.81 respectively...

Post-spray data revealed that the plot treated with flower extracts had the highest mean number of aphids (32.00 plant-1), whereas the least mean number of S. avenae was recorded for stem extracts (25.00 plant-1) after 1 day application. However, after 14 days a significantly lower mean nu...
