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 % ).



Biological control of earhead caterpillar, Helicoverpea armigera Hubner in sorghum
...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 effectiveness of two biopesticides against D. pini ile N. sertifer larvae. 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...

...e efficacy of commercial biopesticides under controlled environmental conditions. 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....

... 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...

...n plots sprayed with mix-biopesticides. It is concluded that biopesticide from these two plants could be utilized for their efficacy against various pests of okra and potato. Keeping the environmentally friendly nature of these biopesticide, compared to synthetic pesticides, it is recommended that more research be directed for assessment of more active compounds that could act as potential candidates for biopesticide. The objective of the study was to find the...

...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...

...atural plant products as biopesticides in the prevention and control of pests and diseases has been increasing. 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...
