“…Raguraman and Singh (1997) reported that topical application at the rate of 0.5 ml per insect at 3, 2 and 1% concentrations of neem oil produced negligible mortality after 24 and 48 h of treatment, corroborating our observations. Mortality increased with increasing dosage and time, with low mortality observed within the first 24 h of treatment.…”

“…Crude seed extract of A. indica acts as a strong growth inhibitor, is acutely toxic and an active feeding deterrent against two lepidopteran species, cabbage looper Trichoplusia ni and the armyworm Pseudaletia unipuncta (Akhtar et al, 2008). Neem oil is not an instant killer (Raguraman and Singh, 1997) but has strong ovicidal and antifeedant effects that inhibit the development of eggs and larvae of E. cautella. The toxicity of the oil results in its protectant effect against insect damage to stored grain.…”

The tropical warehouse moth Ephestia cautella (Walker) is an important storage pest of maize grain. The control of this major moth pest relies heavily on the use of synthetic insecticides. We assessed the biological efficacy of a commercial neem oil (Calneem oil) against E. cautella in the laboratory, using the common grain protectant Actellic as a positive control. Contact toxicity, repellency, effects on oviposition, development and grain damage were assessed. The assays were conducted by treating 100 g of maize grains with Calneem oil concentrations of 3, 5 and 7 ml/l; and Actellic at 2 ml/l. Calneem oil significantly (P, 0.05) reduced oviposition rate, development of eggs and immature stages, and emergence rate of E. cautella progeny in maize grains. Grains treated with Calneem oil had significantly (P, 0.05) reduced grain damage in storage, and the oil had a repellency of 53 -70% compared with the negative control. Calneem oil protected maize grain against damage by E. cautella for 10 weeks, compared with 20 weeks protection by Actellic. There was no resistance development to the oil for three generations of E. cautella. The insects that survived treatment with the LC 90 concentration (12.2 ml/l) of the Calneem oil laid fewer eggs, and some of their progeny were deformed. Calneem oil provided a good level of protection to maize grains against infestation by E. cautella, and may therefore be a suitable substitute for Actellic.

“…However, there is no available literature on the larvicidal potential of C. deodara oil and its fractions against this lepidopteron pest. Himalayan cedar wood oil and its constituents are reported to show insecticidal activities against some other insect pests like the Graham bean weevil ( Callosobruchus analis ), rice weevil ( Sitophilus oryzae ), housefly ( Musca domestica ), and the Chinese bean weevil ( Callosobruchus chinensis) (Raguraman and Singh 1997; Singh et al 1989; Singh and Agarwal 1988; Singh and Rao 1985). Further, C. deodara oil is reported to show toxicity against Lymnaea acuminata when combined with extracts of Azadirachta indica and Embelia ribes (Rao and Singh 2001).…”

Plants and plant-derived materials play an extremely important role in pest management programs. Essential oil from wood chips of Himalayan Cedar, Cedrus deodara (Roxburgh) Don (Pinales: Pinaceae), was obtained by hydrodistillation and fractionated to pentane and acetonitrile from which himachalenes and atlantones enriched fractions were isolated. A total of forty compounds were identified from these fractions using GC and GC-MS analyses. Essential oils and fractions were evaluated for insecticidal activities against second instars of the diamondback moth, Plutella xylostella L. (Lepidoptera: Yponomeutidae), using a leaf dip method. All samples showed promising larvicidal activity against larvae of P. xylostella. The pentane fraction was the most toxic with a LC50 value of 287 µg/ml. The himachalenes enriched fraction was more toxic (LC50 = 362 µg/ml) than the atlantones enriched fraction (LC50 = 365 µg/ml). LC50 of crude oil was 425 µg/ml and acetonitrile fraction was LC50 = 815 µg/ml. The major constituents, himachalenes and atlantones, likely accounted for the insecticidal action. Present bioassay results revealed the potential for essential oil and different constituents of C. deodara as botanical larvicides for their use in pest management.

“…Tenebrio absorbed more tested chemical that resulted in slight high LC 50 values. Cedrus deodara has been found effective against a variety of insects (Raguraman and Singh, 1997, Rahuman et al, 2009, Rao and Singh, 2002, Delbeke et al, 1997). The findings suggesting that formulation chemistry can investigate the longevity of repellent activity and should be developed into commercial repellent products.…”

Cedrus deodara (deodar) is practically used, as insect repellent, in the northern areas of Pakistan but no data available therefore this study was conducted to evaluate the effectiveness of deodar oil as an alternate of conventional insecticides against the larval pest stage of mealworm beetle ( Tenebrio molitor ), by feeding method. The aim of the study was to investigate the effectiveness of deodar oil as an alternate of conventional insecticides against the larval pest stage of mealworm beetle ( Tenebrio molitor ), by feeding method. All tested chemicals showed efficacy against the pests. The LC 50 was determined by probit analysis and was found to be 3.41, 0.086 and 0.023% of larvae treated with deodar oil, Carbosulfan and Imidacloprid respectively The LC 50 treated larvae were subjected to the evaluation of protein activity, qualitatively and quantitatively. The protein level in tested insects was enhanced when treated with Imidacloprid, Carbosulfan and deodar oil. The electrophoretic profile of treated insects showed more bands in insects treated with Cedrus deodara oil. This electrophoretic profile appeared in 4, 5, 7 and 8 bands for tested chemicals including control. Antifeedant activity was observed for C. deodara as larvae were deterred to feed on the food found in the container.
