Star anise, Illicium verum Hook f. as a potential grain protectant against Tribolium castaneum (Herbst) and Sitophilus zeamais Motsch

Chemical composition and the insecticidal activity of certain plants applied as powders and essential oils against two stored-products coleopteran beetles

“…These botanicals were reported as effective grain protectants when tested alone or in combination with natural products such as diatomaceous earth (Athanassiou et al 2004(Athanassiou et al , 2005Kavallieratos et al 2007). Such compounds may act as contact insecticides (Ho et al 1995;Nenaah 2010;Saroukolai et al 2010), fumigants (Rice and Coats 1994;Shaaya et al 1997;Liu and Ho 1999;Kéita et al 2001;Ilboudo et al 2010), repellents (Saim and Meloan 1986;Papachristos and Stamopoulos 2002;Wang et al 2006), and antifeedants Liu and Ho 1999) and may affect certain parameters disrupting the growth rate, life span, and reproductive potential of insect pests (Stamopoulos 1991;Regnault-Roger and Hamraoi 1994;Nyamador et al 2010). Traditionally, plant materials have played an important role in the protection of grains against insect infestation in Africa since ancient times.…”

Assessing the toxicity of NSO (Neem Seed Oil) and NSKP (Neem Seed Kernal Powder) to a bruchid

“…Extraction with hexane and methanol showed a much higher insecticidal activity compared to the extraction with chloroform. Ho et al 35 , reported that the n-hexane extract of the dried fruit of star anise has higher contact toxicity to the stored product beetle, Tribolium castaneum Herbst than Sitophilus zeamais Motsch.…”

Research on One Kind of Essential Oil Against Drugstore Beetle Stegobium paniceum (L.)

“…Several investigations have demonstrated contact, fumigant and antifeedant effects of a range of essential oil constituents against the red flour beetle Tribolium castaneum and the maize weevil Sitophilus zeamais (Ho et al , 1995(Ho et al , 1997. Essential oils from many plants have been developed as pest control agents.…”
