“…Sharma (1995) recommended treatment of maize seeds with neem leaf powder (100g/kg) and ash (10g/kg) for effective reduction in percent seed damage during storage. Ogunwolu and Odunlani (1996) reported that cowpea seeds treated with neem leaf powder (3g/kg) seeds showed reduced bruchid infestation after five months of storage. Anil et al (1998) observed that soybean seeds treated with neem products and untreated seeds did not show any significant differences in germination.…”

This study was undertaken to determine the storability of pre-treated sesame seeds and to compare the effects of inorganic and organic seed treatments on the viability and vigour of sesame seeds during storage. Two hundred grammes of sesame seeds were treated separately with recommended dosages of Neem leaf powder (NLP), Dress force powder (DFP), Dry pepper powder (DPP) and untreated seeds being the control; each treatment placed in air-tight container and stored in a wooden cabinet at average ambient conditions of 26.5°C and 80% RH for a period of 18 weeks. Completely randomized design was used for the experiment, with storage time and seed treatment as factors. Samples were drawn from storage at interval of two weeks and tested for seed viability and seedling vigour. Seed germination, seedling vigour index, speed of germination and rate of germination were evaluated. Analysis of variance (ANOVA) was carried out on the data collected, and treatment means were separated using Duncan's Multiple Range Tests (DMRT). Correlation analysis was also carried out to ascertain the kinds of relationships that exist among the variables evaluated. Observations showed that NLP and DPP treatments had better mean seed germination of 89.53% and 82.35% respectively compared to DFP (46.47%) and control (80.76). NLP also enhanced better seedling vigour index (339.24) throughout the strorage time compared to DFP (99.74). It is therefore recommended that natural botanicals like NLP could be adopted for short and medium term storage of sesame seeds; as it maintaned seed viability and seedling vigour optimally among other treatments.

“…Some of these botanical pesticides include powders from Piper guineensis (Ivbijaro and Agbaja, 1986), Piper nigrum (Rajapakse, 1990), Zanthoxylum xanthoxyloides (Ogunwolu and Odunlami, 1996), root bark of Annona senegalensis (Aku et al, 1998), Capsicum frutescens (Echezona, 2006;Ofuya, 1986), plant mixtures (Arannilewa et al, 2006) and essential oil derived from Artemisia sieberi (Negahban et al, 2007). Expectedly, some of the advantages of these botanical pesticides are their availability and userfriendliness as biological control agents with no adverse effects on the environment.…”

Insecticidal activities of dried Artemisia annua L. leaves were evaluated against bruchid (Callosobruchus maculatus F.) pests in comparison with those of Azadirachta indica, Ocimum gratissimum and a conventional grain storage insecticide, Actellic® 2% dust. Each treatment was added to a mixture of 250 g cowpea seeds and 25 adult bruchids and laid out in a completely randomized design with four replicates. Irrespective of the concentration tested, all three plant materials significantly (P < 0.05) increased mortality rate of adult insects earlier than the control. Higher concentrations of the botanical pesticides equally resulted in an increased reduction in the number of surviving bruchids and reduction to seed damage through a lower number of eggs laid and weevil perforation index (WPI) after 90 days. Comparatively, A. annua was more effective than the other plant materials at all levels evaluated though it was not as effective as Actellic 2% dust. Moreover, differences amongst the efficiency rates and interactions between A. annua and A. indica in three treatment combinations produced a significant (P < 0.05) effect on two of the parameters evaluated. Taken together, all plant materials evaluated here were seen to have significant insecticidal properties and could therefore, be used as environmentally friendly products for controlling bruchid pests during storage of cowpeas with no adverse effects on eventual mammalian consumers as observed during an animal feeding trial in this study.

“…Callosobruchus maculatus (Coleoptera: Bruchidae) is a major insect pest of cowpea. It is a cosmopolitan pest of cowpea in the tropics and subtropics of the world and an important field and store pest of pulse crops in Africa and Asia (Hill, 1983;Ogunwolu and Odunlami, 1996). It is commonly referred to as cowpea weevil.…”

Nutrient composition of cowpeas infested withCallosobruchus Maculatus L. in Zaria.Cowpeas infested with Callosobruchus maculatus, in Zaria were analysed using standard biochemical methods.The analysis was to determine the effect of Callosobruchus maculatus on cowpeas at various stages of infestation. Four varieties "Kannanado", Local brown, "Dan Borno" and IAR-48 were used. Results show significant decrease in moisture with increase in infestation in all the varieties except for 'Kannanado', this was also the case in carbohydrate content for all the varieties used (p < 0.05). The carbohydrate content ( lowest was 10.3%) for uninfested " Dan Borno" while the infested IAR-48 had the highest (12.4%) Slightly infested seed had the highest moisture content (12.0%) while uninfested cowpeas had lowest moisture (5.8%). A trend of increase ABSTRACT in protein content with severity of infestation was observed in the varieties used, though I.A.R. 48 deviated from this pattern (p < 0.05). Uninfested "Dan Borno" had the lowest protein content (1.4 %) and IAR-48 the highest (1.7 %). Lowest lipid content was found in slightly infested seeds ( 15.6 %) and the highest (22.6 %) for the severely infested. A significant increase in lipid and ash contents of the cowpeas with increase in severity of infestation was observed in all the varieties (p < 0.05).The damage caused by C. maculatus to all varieties of cowpea analysed did not significantly affect their nutrient composition though they attract less market value than uninfested varieties.
