“…This result is similar to the work done by UKEH et al (2008), where 5 and 10 g powdered Piper guineense was significantly toxic to Sitophilus zeamais and suppressed F 1 progeny emergence compared to 1 g of powder and the control. This result is also in agreement with the observations of UDO (2005) and ASAWALAM et al (2007), whose studies on plant spices demonstrated that a higher quantity of Piper guineense on Sitophilus zeamais caused significant mortality and also reduced the production of progeny.…”

A laboratory evaluation was carried out to determine the efficacy and phytochemical composition of powdered seeds of Physic nut Jatropha curcas, Yellow oleander Thevetia peruviana and West African black pepper Piper guineense at different dosages (2.5, 5.0, 7.5 and 10.0 g) for the management of Sitophilus zeamais. Treatments were mixed with 50 g of maize and infested with 10 adult S. zeamais in 200 ml air-tight glass vials and kept under ambient conditions (25-30°C and 70-90 RH) for a period of 28 days in August 2015. The trial was laid out in a completely randomized design in four replicates. Results from data analyses showed that treated maize grains in storage recorded significantly (P < 0.05) higher mean mortality levels of adult S. zeamais than the untreated controls. However, there were no significant differences in mean mortality of the weevil at 7, 14, 21 and 28 DAT, except on those stored only for 1 DAT. Batches treated with higher doses (10.0, 7.5, 5.0 g) suffered a higher total mortality of adult S. zeamais; this was significantly (P < 0.05) higher compared with treatments using smaller dosages (2.5 and 0.0 g). Phytochemical analysis of treatments revealed high levels of alkaloids, tannins and phenols in all the plant extracts. The flavonoid contents were also high in Piper guineense and Permethrin, but lower in Jatropha curcas and Thevetia peruviana. These compounds are known to possess insecticidal properties that may have been responsible for the mortality of Sitophilus zeamais.

“…The use of botanical pesticides to protect plants from pests is very promising because of several distinct advantages (Parugrug and Roxas, 2008). Many plant powders have been found to be very effective in the control of S. zeamais attacking maize grains in the storage (Adedire and Ajayi, 1996;Asawalam and Emosairue, 2006;Asawalam et al, 2007;Kabeh and Jalingo, 2007;Mulungu et al, 2007;Parugrug and Roxas, 2008;Ukeh et al, 2008;Danjumma et al, 2009). However, studies on the effects of these powders on the insect pest attacking guinea corn grains have not been given much attention.…”

Plant powders prepared from five plant species were tested under constant conditions at 30 ± 2℃ and 60-65% r. h. for their ability to protect sorghum grains against Sitophilus zeamais in storage. Doses at 0.5, 1.0 and 2.0g and 0.12g of the check (permethrin (0.6%) were applied for assessments of adult mortality, emergence and damage. Leaf powders of E. balsamifera, J. curcas and L. inermis gave the highest adult mortality (60.0-100%), while peel powder of C. sinensis and leaf powder of L. hastata recorded 47.50-82.50% adult mortality. Least adult emergence (0.00%) was observed when 2.0g of J. curcas was applied, while the highest (57.82%) was obtained from 0.5g L. hastata. All the plant powders showed significant (p < 0.05) adult mortality against S. zeamais with weevil perforation index (WPI) of < 50.00. This study was designed to observe the possibility of using plants parts to reduce grain damage caused by insect pests during storage.

“…Studies on the effect of substances extracted from Annonaceae on insect behavior are rather scarce. Ukeh et al (2008) found that the application of seed powder of Monodora myristica to corn seeds provides significant oviposition deterrence for S. zeamais and suppresses entirely the F1 progeny at doses EFFECTS OF ORGANIC PLANT EXTRACTS ON BEHAVIOR OF Sitophilus zeamais MOTS.

The aim of the present study was to evaluate the action of organic plant extracts from different parts of some species on host selection behavior of Sitophilus zeamais (Coleoptera: Curculionidade) adults. With the exception of extracts prepared from Aristolochia paulistana, all other tested plant extracts showed effect on behavior of S. zeamais adults, depending on concentration and solvent used in their preparation. The most pronounced repellent and/or deterrent effects were obtained with nonpolar extracts (in hexane and dichloromethane) of Annona montana, Annona mucosa, and Casearia sylvestris. On the other hand, ethanolic extracts from branches of C. sylvestris, leaves of A. montana, and leaves and seeds of A. mucosa were attractive and/or stimulant of feeding and/or oviposition of S. zeamais adults, depending on the concentration used. Thus, these extracts are promising sources of attractive compounds to be used in food baits in monitoring traps or even as repellents of stored grain pests.
