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 % )....

...iment was conducted with biopesticides viz., Nomurae rileyi (Farlow) Samson and NPV of Helicoverpa armigera (HNPV) and compared with chemical control with Melathian 5% @ 30 kg.ha-1 for the management of ear head caterpillar (H. armigera) in sorghum ecosystem of University of Agricultural Sciences, Dharwad. The mycoinsecticide N. rileyi was highly infective at both the dosages 1x108 conidia per litre & 2x108 conidia per litre against H. armigera as compared...

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 doses of Pyrethrum and Bacillus thuringiensis biopesticides (Spruzit® Neu from 150ml to 600ml/100 l, and DiPel® DF BT 100 to 500 g/100 l) were applied against the larvae of D. pini and N. sertifer their impact was monitored under laboratory conditions. The finding of the st...

Bio pesticides are important alternates for chemical control of economically damaging insect pests like leaf worm, Spodoptera litura Fabricius. In this study, two commercial products including Dipel with Bt sub speciess kurstaki and Turex with Bt sub speciess kurstaki and aizawai were tested against three early larval instars of S....

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...

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-

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...

Nematicidal activity of “Black plum Syzygium cumini, leaf aqueous, ethanol and methanol extracts were investigated for managing the population of Meloidogyne javanica, in tomato. In laboratory conditions second-stage juveniles (J2) mortality was recorded after 24, 48 and 72 h of incubation in concentrations of 0.25, 0.5 or 1%. Maximum mortality...
