    Nathan S, Kalaivani K, Murugan K. Effects of neem limonoids on the malaria vector Anopheles stephensi Liston (Diptera: Culicidae). Acta Trop. 2005;96:47-55 pubmed
    ..In general, first to third larval instars were more susceptible to the neem limonoids. Neem products may have benefits in mosquito control programs. ..

    Senthil Nathan S, Kalaivani K, Chung P, Murugan K. Effect of neem limonoids on lactate dehydrogenase (LDH) of the rice leaffolder, Cnaphalocrocis medinalis (Guenée) (Insecta: Lepidoptera: Pyralidae). Chemosphere. 2006;62:1388-93 pubmed
    ..Azadirachtin was the most potent in of all the limonoids in all experiments indicating strong enzyme inhibition. Clear dose-response relationships were established with respect to LDH activity. ..

    Senthil Nathan S, Kalaivani K, Sehoon K. Effects of Dysoxylum malabaricum Bedd. (Meliaceae) extract on the malarial vector Anopheles stephensi Liston (Diptera: Culicidae). Bioresour Technol. 2006;97:2077-83 pubmed
    ..In general, first and second instars were more susceptible to leaf extract than older insects. Clear dose-response relationships were established, with the highest dose of 4% plant extract causing 97% mortality of first instars...

    Senthil Nathan S, Choi M, Paik C, Seo H, Kim J, Kang S. The toxic effects of neem extract and azadirachtin on the brown planthopper, Nilaparvata lugens (Stål) (BPH) (Homoptera: Delphacidae). Chemosphere. 2007;67:80-8 pubmed
    ..The results clearly indicate the simple NSKE (aqueous, ethanolic or both), containing low concentrations of AZA, can be used effectively to inhibit the growth and survival of BPH. ..

    Nathan S, Hisham A, Jayakumar G. Larvicidal and growth inhibition of the malaria vector Anopheles stephensi by triterpenes from Dysoxylum malabaricum and Dysoxylum beddomei. Fitoterapia. 2008;79:106-11 pubmed
    ..They also affected the reproductive potential of adults by acting as oviposition deterrents. The highest concentration tested (10 ppm) of both compounds evoked more than 90% mortality and oviposition deterrence. ..
  6. Senthil Nathan S, Choi M, Paik C, Seo H, Kalaivani K. Toxicity and physiological effects of neem pesticides applied to rice on the Nilaparvata lugens Stål, the brown planthopper. Ecotoxicol Environ Saf. 2009;72:1707-13 pubmed publisher
    ..The results clearly indicate the neem-based pesticide (Parker Oil and Neema), containing low lethal concentration, can be used effectively to inhibit the growth and survival of N. lugens. ..
