“…The act of weakening of adults by botanical powders may make them lay fewer eggs than the normal leading to less hatchability to larvae and final metamorphosis to adults. Different botanicals effectiveness at higher dosage to various storage insect pests have been reported by several authors (Huang et al, 2000;Tripathi et al, 2000;Adedire and Lajide, 2003;Akinkurolele et al, 2006;Mbailao et al, 2006;Wang et al, 2006;Negahban et al, 2007;Oni and Ileke, 2008;Shahaf et al, 2008;Ayvaz et al, 2010;Bachrouch et al, 2010;Sivakumar et al, 2010;Adedire et al, 2011;Ileke and Oni, 2011;Mahmoudvand et al, 2011).…”

In storage, maize grains are severely destroyed by insects and other storage pests. One of the primary causes of grain loss in stored maize is the damage caused by maize weevil, Sitophilus zeamais. A study was conducted to evaluate selected locally available botanical powders and cooking oils for their effectiveness as grain protectants against maize weevils at JUCAVM in year 2011. The plant powders and cooking oils were compared with untreated control and Malathion super dust as standard check. The experiment was laid-out in Completely Randomized Design with 13 treatments each replicated thrice. Different dependent variables such as cumulative adult mortality, F 1 progeny emergency, grain damage were assessed. The results revealed that, among the botanical powders, there was an increased cumulative adult S. zeamais mortality, i.e. higher mortality, from powders of Chenopodium ambrosoides (70% with LT 50 of 6.50 days), Azadiricta indica leaf (70% with LT 50 of 6.00 days), A. indica bark (70% with LT 50 of 8.40 days) and Tagetus erecta (70% with LT 50 of 9.20 days) after 20 days of exposure periods. Apart from the untreated control, low mortality of S. zeamais adult was recorded from Allium sativum (50% with LT 50 of 18.01 days), C. citratus (55% with LT 50 of 18.30 days), Maesa lanceolata (55% with LT 50 of 16.20 days) and Echinops kebericho (55% with LT 50 of 14.50 days) after 20 days of exposure periods. Highest S. zeamais adult mortality of 95%, 100% and 100% was recorded from Brassica carinata oil, Gossypium hirsutum oil and the standard chemical Malathion, respectively with LT 50 of less than one day in all cases. Maximum number of progeny was emerged from untreated check from 25 th~4 0 th days of exposures with cumulative increase (2 to 14 adults). There was no F 1 progeny emergency from the three treatments (oils and Malathion) over the exposure periods reassuring the potency of the cooking oils against S. zeamais. As a result there was no perforated seed; no weight loss and maximum germination percentage of 94.60% were registered from the two cooking oils on par with the Malathion (95.50%). In conclusion, the two cooking oils were found to be the most potent bio-insecticides on par with standard check, Malathion and they can be used in integrated management of maize weevil, S. zeamais.

“…annua has found a number of different practical uses in agriculture and public health. These include repellency against beetles (16), larvicidal activity against Anopheles stephensi (17), insecticidal activity against elm leaf beetle (18), and use as an acaricide (19). Moreover, AN and its derivatives have effects on a number of viruses (20), a variety of human cancer cell lines (20,21), and several neglected tropical parasitic diseases including schistosomiasis (22), leishmaniasis (23,24), New-and Old-World trypanosomiases (25), and some livestock diseases (26).…”

Pharmaceutical monotherapies against human malaria have proven effective, although ephemeral, owing to the inevitable evolution of resistant parasites. Resistance to two or more drugs delivered in combination will evolve more slowly; hence combination therapies have become the preferred norm in the fight against malaria. At the forefront of these efforts has been the promotion of Artemisinin Combination Therapy, but despite these efforts, resistance to artemisinin has begun to emerge. In 2012, we demonstrated the efficacy of the whole plant (WP)-not a tea, not an infusion-as a malaria therapy and found it to be more effective than a comparable dose of pure artemisinin in a rodent malaria model. Here we show that WP overcomes existing resistance to pure artemisinin in the rodent malaria Plasmodium yoelii. Moreover, in a long-term artificial selection for resistance in Plasmodium chabaudi, we tested resilience of WP against drug resistance in comparison with pure artemisinin (AN). Stable resistance to WP was achieved three times more slowly than stable resistance to AN. WP treatment proved even more resilient than the double dose of AN. The resilience of WP may be attributable to the evolutionary refinement of the plant's secondary metabolic products into a redundant, multicomponent defense system. Efficacy and resilience of WP treatment against rodent malaria provides compelling reasons to further explore the role of nonpharmaceutical forms of AN to treat human malaria. malaria | drug resistance | artemisinin | Plasmodium | evolution

“…Coumarin and thujyl alcohol found in Artemisia abrotanum (L.) (Asteraceae) were shown to repel the tick Ixodes ricinus (L.), (Ixodidae) (Tunón et al, 2006). Essential oils from A. vulgaris are repellent to Tribolium castaneum (Herbst) (Tenebrionidae) (Wang et al, 2006), and those from A. annua have been shown to be both repellent and toxic to all life stages of the pulse beetle, Callosobruchus maculatus (F.) (Chrysomelidae) and the red flower beetle, T. castaneum (Tripathi et al, 2000).…”
