“…The total inhibition rate in adult emergence of the weevils in grains treated with ethanolic leaf extracts of the test botanicals at varying concentrations recorded in this study agrees with Ileke (2014) who reported a complete inhibition of adult emergence of S. zeamais when exposed to aqueous extracts of A. boonei. The suppression activity in adult emergence of L. inermis was also recorded against C. maculatus (Suleiman and Suleiman, 2014;Chudasama et al, 2015). It is found out that the botanicals might be lethal to the eggs deposited and as such led to inhibition in adult emergence of the weevils in the treated grains, concurring with Chudasama et al (2015) that poisonous substances present in the extracts may enter into the egg through chorion and suppressed further embryonic development.…”

“…In view of the promising effects of some botanicals against insect pests of stored products, Euphorbia balsamifera Aiton, Lawsonia inermis L., Mitracarpus hirtus (L.) DC and Senna obtusifolia L. were selected for this study due to their local availability, and reported efficacies of some of them against other insect pests such as Callosobruchus maculatus F. and Trogoderma granarium Everts (Al-Moajel, 2004;Chudasama et al, 2015). This study was therefore aimed at evaluating effect of ethanolic extracts of the aforementioned botanicals on the control of S. zeamais infesting stored sorghum grains.…”

Entomocidal activity of ethanolic leaf extracts of four plant species namely Euphorbia balsamifera Aiton, Lawsonia inermis L., Mitracarpus hirtus (L.) DC. and Senna obtusifolia L. were evaluated in order to assess their protectant ability to stored sorghum against Sitophilus zeamais Motsch. The botanicals were applied to 20 g of sorghum grains at the rate of 25, 50 and 100 mgml-1 , while no extracts was added to the control. Percentage repellency was recorded at 24 h after exposure (HAE) while adult mortalities of the weevils were obtained at 3 days after treatment (DAT). Adult emergence and grain perforations were recorded at 49 and 84 DAT, respectively. Repellency levels of the botanicals against S. zeamais ranged from 87.05 ± 0.45 to 100.00 ± 0.00%. Also, the ethanolic extracts resulted in high adult mortalities of the weevils in the treated sorghum grains. No adult emergence was recorded in grains treated with the botanical extracts. Highest (10.00 ± 2.04%) grain perforations among the treatments were observed in 25 mgml-1 of S. obtusifolia, while 2.50 ± 1.25% was the least in the highest concentration of E. balsamifera. Findings of the study have revealed that the selected botanicals could serve as stored sorghum protectants against S. zeamais infestations.

Hexane, dichloromethane and methanol extracts of the roots of Piper sarmentosum Roxb. were screened for toxicity towards Sitophilus oryzae (L.), Rhyzopertha dominica (F.), and Plodia interpunctella (Hübner) and the hexane extract exhibited the highest mortality percentage. Bioassay-guided fractionation of the hexane extract resulted in the isolation of asaricin 1, isoasarone 2, and trans-asarone 3. Asaricin 1 and isoasarone 2 were the most toxic compounds to Sitophilus oryzae, Rhyzopertha dominica, and Plodia interpunctella. Sitophilus oryzae and Rhyzopertha dominica exposed to asaricin 1 and isoasarone 2 required the lowest median lethal time. Insecticidal activity of trans-asarone 3 showed consistent toxicity throughout the 60 days towards all three insects as compared to asaricin 1 and isoasarone 2. Asaricin 1 and isoasarone 2 at different doses significantly reduced oviposition and adult emergence of the three insects in treated rice. Trans-asarone 3 had lowest toxicity with highest LC and LT values in all tested insects relative to its mild oviposition inhibition and progeny activity. Moreover, asaricin 1 and isoasarone 2 significantly inhibited acetylcholinesterase in comparison with trans-asarone 3 and the control. Acetylcholinesterase inhibition of Rhyzopertha dominica and Plodia interpunctella by asaricin 1 and isoasarone 2 were lower than that of Sitophilus oryzae, which correlated with their higher resistance.

“…Consequently, botanical based insecticides have been recommended as alternatives to conventional insecticides for grain protection because they are more innocuous to the environment (Uddin II and Adesiyun, 2012), less toxic to non-target organisms (Ojumoola et al, 2017) and safer for grain treatment (Adedire, 2003). Neem (Azadiractha indica A. Juss) has been widely reported to possess a number of biological, medicinal and pesticidal (Biswas et al, 2002;Uddin II and Abdulazeez, 2013;Chudasama et al, 2015).…”

In the absence of effective protection, grains of legumes may be completely decimated when attacked in storage by the cowpea bruchid, Callosobruchus maculatus. The use of botanical insecticides has been reported as ecologically innocuous alternatives to conventional insecticides for the control of C. maculatus in stored legume grains. This study thus investigated how legume type influenced the emergence of C. maculatus and its susceptibility to the aqeous extract of neem leaf (a botanical based insecticide). Thirty (30) C. maculatus adults from the same population were reared for 4 generations on improved varieties of cowpea (IT89KD391), mung bean (NM 92) and soybean (TGX 1448) seeds under laboratory conditions. While both cowpea and mung bean supported the emergence of adult C. maculatus in all the four filial generations studied, emergence in soybean terminated after first filial generation. Susceptibility of fourth filial generation adult beetles from cowpea and mung bean to neem leaves aqueous extracts was subsequently tested by contact application. Treated adult C. maculatus of the mung bean line were found to be significantly (P<0.05) more susceptible to the botanical extract than those of the cowpea line. It was thus concluded that cowpea and mung bean seeds are more suitable for the emergence of adult C. maculatus than soybean seeds and that its management in storage with neem leaves aqueous extract should be done bearing in mind that the type of legume being treated might influence the effectiveness of the botanical insecticide.
