K.N. Ahmed , M.A. Al-Helal, N-E-P. Khanom, S. Bulbul

Control strategies of papaya mealybug, Paracoccus marginatus Williams & Willink infesting vegetable crops in Bangladesh
...l by this mealybug. Five biopesticides i.e., tobacco medicine (100 %), tobacco leaf extract (20 % ), mehgoni seed oil (5 % ), castor seed oil (5 % ) and neem seed oil (5 % ) were used to assess their effects on the mortality of P. marginatus . It is evident that tobacco medicine exerted the best result in terms of control followed by neem seed oil, mehgoni seed oil, castor seed oil and tobacco leaf extract (20 % ).

...etter as compared to the biopesticide based modules in managing the attack of sucking pests and pod borer of cowpea. The pesticide based IPM-II module resulted in the highest per cent reduction of pod borer population (91.17%) and the highest pod yield (9.85 t/ha). The IPM and biopesticide based management modules resulted in poor cost-benefit ratio. However, the biopesticides and new ecof...

...Pakistan. Development of biopesticide is an attractive strategy to minimize the problems of pest resistance, environmental pollution and human health concerns. The isolates of S. litura nucleopolyhedroviruses (SltNPV) were collected from infected larvae fed on natural cotton crops. The NPV was isolated from the larvae and viral occlusion bodies (VOBs) were detected using a light microscope. The toxicity of native isolates against S. litura also s...

... different chemicals and biopesticides. DBM has shown resistance against 12 different strains of Bacillus thuringiensis (Bt) and 91 active ingredients of agricultural chemicals globally. Alternative ways should be explored to control DBM. Berberine is an insect toxic alkaloid and produced by plants of family Berberidaceae. Berberine Bridge Enzyme (BBE) gene involved in the synthesis of berberine was isolated from Berberis lyceum and over expressed in Arabidops...

Phytochemical Screening of Neem and Black Pepper for Bioefficacy against Insect Pests of Okra and Potato

Bushra Baig and Saeeda Yousaf*

...) were dominant. The mix-biopesticide of Black pepper and Neem in comparison to their individual impact showed the highest insecticidal efficacy against whitefly and aphids. The plots sprayed with mix-biopesticide showed the highest yield of okra and potato crops along with a healthier plant growth. The highest yield of Okra (52 kg) and Potato (272 kg)and their plant growth was recorded in plots sprayed with mix-

...for alternatives such as biopesticides which are environmental friendly and economical. Therefore, in the present study, the toxicity of eight plant extracts and their green synthesized nanoparticles was evaluated against A. albopictus. The maximum mortality of 88% of 3rd instar larvae of A. albopictus was caused by datura extract followed by neem and clove. On the other hand, neem and clove extracts caused the maximum mortality...
