The study was conducted to evaluate the toxic effect of different insecticides at different concentrations against Phenacoccus solenopsis. Leaf-dip bioassays were achieved to measure the toxicity of combination insecticides and biopesticide. The results revealed that the highest mortality were recorded at 1% concentration of each treatment by Profenophos + cypermethrin (90%), Aza-d 1% (96.67%) followed by chlorpyriphos + cypermethrin (75%) and Aza-d 1% (96.67%) showed the significantly different result as compared to all other treatment. Lowest mortality was recorded by Triazophos + deltamethrin (39.33%), Verticillium (36.67%), Beauveria (34%) and Aza-d 0.1% (23.33%) after 12 hours. LC50 values were calculated, among all the value, 0.025 LC50 at 1% concentration of Azad-d 1500ppm gave the better result as compare to the other value of LC50. However among all the value of LT50 values among all the value calculated, LT50 1.2 hour in case of Profenophos + cypermethrin 44EC at 1% concentration was declared best.

Incidence of Fall Armyworm Spodoptera frugiperda Smith, J. E., on Maize was observed in Pantnagar... more Incidence of Fall Armyworm Spodoptera frugiperda Smith, J. E., on Maize was observed in Pantnagar, Udham Singh Nagar, Uttarakhand in last week of July 2019. Identifiaction of the pest was confirmed based on the morphological characteristics. Third instar larvae of the pest were brought to the laboratory and reared. The larvae had undergone to pupation nine days after collection. Pupal period lasted for 4 days. Adults emerged were left for mating and egg laying. The mating period was found to last for 5 days. Eggs were laid in batches of 80 to 160. Incubation period was 4 days. The pest has a devastative record on various crops in South India. The spread of this voracious pest into Uttarakhand was highly notable due the economic loss it causes. The present report gives an alarm for the state to take preventive and control measures against the pest.
