Exploration of potentialities of plant derivatives as insecticidal and phagodeterrant against brown planthopper (Nilaparvata lugens S.)Author(s):
Kale GB, Karnewar SD, Dhawale RN and Dubey VKAbstract:
In a greenhouse trial the oil emulsion of neem (Azadirachta indica A. Juss.), mahua (Madhuca longifolia M. latifolia), Karanj (Pongamia glabra L.), Ratanjyoth (Jatropha curcas) and linseed (Linum usitatissimum L.) and crude extracts of neem, mahua, karanj and linseed were tested at different concentrations for their effects on mortality and feeding behaviour of brown planthopper (BPH), Nilaparvata lugens, which is a vector of ragged stunt and grassy stung viruses. Treatments with neem oil and karanj oil @ 2 per cent each and karanj cake extract @ 5 per cent recorded the highest mortality rate of BPH nymphs however, mauha cake extract @ 5 per cent had showed least mortality of BPH nymphs. While, adult BPH feeding rate was very low in plants treated with karanj oil @ 2 per cent and neem oil @ 2 per cent indicating the phagodeterrant action against BPH (Nilaparvata lugens).Pages: 32-34 | Views: 235 | Downloads: 98Download Full Article: Click Here
