  A survey of arthropods used in traditional medicine was carried out among the people of southwestern Nigeria to examine the importance of arthropods and their by products in life and economy of the people and to provide a compendium of the traditional use of arthropods and their byproducts for future references. Open ended structured questionnaires were administered to elicit information from the rural based herbalists, farmers and those traders in animals for traditional purposes. Seventeen different species of insecta, two species of Myriapoda, one species of Crustacea, one species of Arachinda and three species of Mollusca used in the curing of ailments such as eye defects, various sickness in children, libido in men, arthritis, dizziness, thunderbolt, bedwetting, wounds, mental illness, child delivery, yellow fever, healing of bone fractures etc. Nine species of insects, two species of arachinda, one species of myriapoda and two species of Mollusca were used for rituals such as for defense, coronation, chieftaincy, wedding and naming ceremonies, good fortune, to fight against enemy and favour, forceful command and blessing and detection of thunderbolt (Magun) and for finding, husband and wife, appealing to gods and witches, soothsaying (Afose), to invoke mental development on people and money rituals, appealing to witches for spiritual protection and prosperity, used to confer immunity on man against infectious disease. Few species of insects in particular has some taboo associated with the use in traditional medicine. The results suggest that more research should be done in this area to bring back the ethnozoological knowledge of vanishing culture.

  The study evaluated a method termed “top bar spacing” in Kenya top bar hives to stimulate propolis collection by worker bees from tree buds at University of Agriculture, Abeokuta (UNAAB). Ogun State, Nigeria and Olupakun village, Abeokuta, Ogun State, Nigeria. There were four treatments: hives with top bars spaced at 0.2, 0.4, 0.6 and 0.8 cm. Hives with closely-spaced top bars served as control. The studies were conducted between August 2008 and March, 2009 and repeated between August 2009 and March, 2010. The honey yield, propolis yield, weight of dry pressed comb, number of ripe harvested combs and number of unriped combs were significantly (p<0.05) higher in year 2010. Likewise, the honey yield, propolis yield, weight of dry pressed comb, number of ripe harvested combs and number of unriped combs were significantly(p<0.05) higher in Olupakun village. The propolis collected in hives with spaced top bars were significantly (p<0.05) higher than propolis in hives with closely-spaced top bars. The honey yield, weight of dried pressed comb and number of ripe harvested combs were significantly (p<0.05) lower in hives with differently-spaced top bars. The study shows that a method of “top bar spacing” could stimulate collection of propolis from botanical sources by worker bees. This method could therefore be used by bee keepers with bias for propolis marketing to gather propolis.

  Fermented foods are estimated to constitute about a quarter of the foods consumed worldwide. These foods help in improving nutritional value and safety against bacterial pathogens. Pathogens have however been isolated from some fermented beverages and so, the microbial quality of Kunnu-zaki beverage produced and sold in some locations in Ile-Ife was determined. Five samples of kunnu were collected in duplicate from five different locations. Viable count, coliform count, isolation and characterization of isolates in the sample were done. Antibiotics susceptibility of the isolates was done thereafter. The kunnu samples were serially diluted and these were inoculated into nutrient agar, lactose and MacConkey broth for viable and coliform count, respectively. Isolation and characterization were done using various selective and differential media. The second sample has the highest viable count with 1.79x105 cfu mL-1. All the samples collected were positive for coliform count. Nine different enteric bacteria were isolated with 46.2% of the bacteria being coliform bacteria. The organisms isolated include Escherichia coli, Citrobacter freundi, Shigella sonnei, Salmonella sp. and Proteus mirabilis. Antibiotics sensitivity profile revealed that the most susceptible antibiotics to all the isolates was ofloxacin with 92.3% of the isolates sensitive to it while the least susceptible antibiotics was amoxicillin having 15.4% of the isolates sensitive to the antibiotics. Citrobacter freundii isolated from the first kunnu sample was resistant to all the antibiotics used while Providential alcalifaciens isolated from the third kunnu sample was sensitive to all the antibiotics.
