“…The present study indicates that P. guineense and M. oleifera have insecticidal properties against T. granarium in accordance with previous reports of insecticidal properties of the two plant species against stored product pests (Jood et al 1993;Lale and Alaga 2001;Lale and Yusuf 2001;Asawalam et al 2007). The effectiveness of the plant powder on the test beetle was exposure duration dependent.…”

Plant powder formulation is cheap since organic solvents are not used.…”

Laboratory studies were carried out to investigate bioactivity of Piper guineense seeds and Moringa oleifera leaf powders applied singly or in a mixture against larvae and adult Trogoderma granarium Everts in airtight containers. Three levels (0.0 g, 0.5 g, and 1.0 g/20 g groundnut seeds) of the plant powders were used and pirimiphos-methyl was applied at 0.01 g/20 g seeds (recommended dose). Another control consisting of untreated seeds with aerated lids was included in the bioassay. Both larvae and adults were not killed in control with aerated lids throughout the experimental period and larvae were also tolerant to airtight storage conditions. Adults were more susceptible to plant powders than larvae and adult mortality recorded in P. guineense at 1.0 g, 0.5 g and M. oleifera at 1.0 g/20 g seeds were not significantly different from the mortality observed with the recommended dose of Pirimiphos methyl at five days after treatment (DAT). Larval mortality observed in a mixture of both plants (1:1; w/w) caused significantly higher mortality (77.5%) than other treatments at 5 DAT. All treatments (P. guineense and M. oleifera applied singly or in a mixture) were repellant to larvae T. granarium with 60% repellency recorded in the mixture of plants, 50% repellency in P. guineense and 30% repellency in M. oleifera slurry. The water absorption capacity of treated seeds was not affected by treatment with plant powders and ranged from 31.98% to 37.59%.

Plant materials, such as essential oils and extracts, are useful tools for insect pest control. In this study, we report the repellent activity and fumigant toxicity of garlic extract Allium sativum L. (Amaryllidaceae) against larvae and adults of the red flour beetle, Tribolium castaneum (Herbst) (Col., Tenebrionidae). Experiments were carried out at 27 ± 1°C and 60 ± 5% RH in darkness. Results showed that mortality increases with increasing garlic extracts concentration and time. LC 50 values for larvae at 24 and 48 h were 267.37 and 145.8 μl/l air, and for adults, they were 127.90 and 90.8 μl/l air, respectively. The concentration of 225.8 μl/l air of the garlic extract yielded was 83.3% mortality of larvae after 48 h. The garlic extract had a strong repellent activity towards T. castaneum when tested in a filter paper arena test. After 4 h exposure to a low concentration (2.13 μl/cm 2 ) of garlic extracts, more than 95% repellence was achieved. Our results indicate lethal and repellent effects of garlic extracts on T. castaneum.

“…guineense (also called African pepper, Ashanti pepper, Benin pepper, false cubeb, Guinea cubeb, uziza pepper and Guinea pepper) belonging to the family Piperaceae are semi-cultivated in countries such as Nigeria where the leaves and seeds are used as flavouring agent (Asawalam, et al, 2007). Studies have shown that apart from the use of these plants as spices and condiments, they have several other wide applications in the local treatment and management of many diseases.…”
