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...

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...

The results showed that fall armyworm damage was lowest in synthetic pesticide treatment, followed equally by eucalyptus-based biopesticide, sand mixtures of neem, red pepper, ash and turmeric, while the highest damage was recorded where no management was done. For the occurrence of the non-target arthropods during live observations, ants and whitefl...
