Abstract:
The use of pesticides for effective pests control has generated a lot of concerns relating to public health and environmental pollution. With the new European Union (EU) Legislation on Maximum Residue Levels (MRLs) allowed on cocoa beans and its products, this study aimed to assess the pesticide residue on cocoa beans from Ondo State, Nigeria. Dry cocoa beans were collected from four different towns having cocoa farm industries in Ondo State, Nigeria. The five locations are Akure, Idanre, Ondo and Ore. Assessment of pesticide usage was done using structured questionnaires to obtain information on the extent of use of pesticides. Pesticide Residues was carried out using GCMS and retention times were used for identification of pesticides and quantified using external calibration method. Generally, the pH of the cocoa beans from the four locations was less acidic, pH ranging 5.90-5.60 and moisture content of cocoa beans sample from Akure was significantly different (p < 0.05) from other three locations with highest moisture content (6.60%). Majorly, 94.2% of the farmers were affected by pests and 71.6% of the farmers resolved in using pesticides in solving this challenge. There were no active ingredients of pesticide residue detected from these four locations except the inert ingredients. Absence of active ingredients of pesticides in the sampled cocoa beans implies that pesticide residue is phasing out gradually in cocoa industry in Ondo State.

Abstract:
The insecticidal activities of Cleistopholis patens and Eugenia aromatica (powder and ethanolic extracts) on maize weevil was carried out to determine its efficacy on mortality of Sitophilus zeamais, percentage reduction of the maize weevil, percentage seed damage and Weevil Perforation Index (WPI) as an index of insecticidal activity. Five different levels of concentration were used (0.5g, 1.0g. 1.5g. 2.0g and 2.5g w/w of powder), (0.5ml, 1.0ml,1.5ml, 2.0ml and 2.5ml w/v of ethanolic extracts) and (0.1g, 0.2g, 0.3g, 0.4g and 0.5g w/w of powder) for the percentage reduction, seed damage and WPI. The plant powders and extracts showed significant (p

Abstract:
The objective of this research is to quantify the residue of chlorinated pesticide content of the four grain samples and compare their residues content with FAO/WHO MRLs. Permethrin in bean samples from location 2 (5.04 ppm) and 3 (4.44 ppm) were significantly different (p < 0.05) from the samples from location 4 (0.00 pm) and also different from sample from location 1 (2.0 ppm). There were a few exceptions in some markets such as Heptachlor (B) which was not detected in the beans sample from Location 1. There was a conspicuously high quantity (8.49 ppm) of Permethrin in the rice samples from Location 4 but Endrin was found to be absent in all rice samples. Likewise Endrin was found to be absent in all wheat samples while only the sample from Location 2 contained Lambda Cyalothrin but did not contain p,p-DDD. The Permethrin levels in wheat samples were also considerably high. The maize samples had the highest concentration in many of the organochlorine pesticide. The concentration of alpha-BHC in maize was 0.03 ppm, beta-BHC had a concentration of 0.14 ppm, 0.073 ppm for Lindane, 0.09 ppm for Chlorothalonil and 0.14 ppm in Aldrin. Almost 80% of the pesticide monitored exceeded their MRL; while some pesticide concentration slightly exceeded their maximum residue limit some concentrations were significantly higher than their MRL.

Abstract:
In this study, the insecticidal efficacy of the powder and extract of Uvaria afzelli seed is evaluated against different life stages of Plodia interpunctella at the ambient temperature of 28 ± 2 oC and 75 ± 5 % relative humidity. The powder of the plant was tested at the rate of 0.1, 0.2, 0.3 and 0.4g dosages, while the extract was tested at 1, 2, 3 and 4 % concentrations per 20g of maize. The contact and fumigant toxicity of the plant was observed on the mortality and emergence of the adult moth. All the dosages and concentrations of the plant used as treatment through contact toxicity completely inhibited the emergence of the adult moth. Also, all the dosages of plant powder used as treatment achieved 100 % of insect mortality within ninety-six hours of application except the 0.1g dosage which recorded 98.17 % mortality. Within seventy-two hours of exposure, the powder of the plant used as fumigant recorded 100 % mortality of the moth at 0.4g dosage while the extract achieved 100% mortality within twenty-four hours regardless of the concentration used. Also, at 0.1g and above, for both extract and powder, 100 % inhibition of egg hatchability and adult emergence was recorded. The powder and extract of U. afzelli are highly toxic against different life stages of P. interpunctella when used as contact toxin and fumigant

Abstract:
Pesticides are beneficial in reducing the loss cause by insect infestation on grains but its toxicity and persistence in the environment is of health concern. Cereal grains preserved with insecticide are considered to be good for consumption if it’s active content substances of insecticide do not exceed the maximum residue limits (MRLs). The objective of this research is to quantify the residue of chlorinated pesticide content of the four grain samples and compare their residues content with FAO/WHO MRLs. Dichlorvos was found in all the bean samples with quantities ranged from 0.06 - 0.212 ppm and there was no signifi cant difference (p >0.05) between location 2 (0.08 ppm) and Location 3 (0.06 ppm). Likewise on rice, dichorvos was present in all locations, ranged from 0.04 to 0.37 ppm and its residues detected in each location were signifi cantly different (p < 0.05) from one another. For wheat, carbaryl was detected in location 4 (0.21 ppm) only, likewise pirimiphos-methyl in location 2 (0.75 ppm). Carbofuran, malathion, chlorpyrifos and parathion were not detected in any of the maize samples. Pirimiphos-methyl had the highest concentration in the beans sample (0.5 ppm) and had the lowest concentration in rice (0.07 ppm). Wheat had the highest number of insecticide residue and followed by rice sample. Almost 99% of the pesticides monitored were below their MRL, while only chlorpyrifos concentration slightly exceeded its maximum residue limit in bean. Nevertheless, their detection further attests to their persistence and efforts should still be geared towards appropriate uses of pesticides

Year Published:

Abstract:
This study investigated the extent of well water contamination in dry and rainy seasons through infiltration of coliform bacteria from sewage pits in their proximity in Akure. Total and Faecal coliform counts of twenty household wells were investigated between the months of March and July with respect to proximity of wells to sewage pits, orientation of wells to sewage pits, and other well characteristics. All wells studied were assessed to be vulnerable to contamination with observable differences in characteristics, physicochemical parameters, total coliform counts and faecal coliform counts. Asides pH which was higher in the dry season, all other parameters had lower values in the dry season. At an average distance of 17.6 m from the sewage pits, all well water sampled had greater coliform counts than the WHO recommended level for drinking water (< 1 cfu/mL). Correlations between coliform counts of water samples and the distances of the wells to sewage pits was positive and not significant for both total and faecal coliform in dry season, while it was negative and significant for both total and faecal coliform in the rainy season. Topography, and distance between wells and sewage pits were prominent factors responsible for well water contamination. Amounts of coliforms found in wells were significantly affected by seasonal variation. It is thus suggested that wells be sited up-gradient and at safer distances away from sanitary systems in the ultimate bid to reduce groundwater pollution and the occurrence of water borne diseases.

Abstract:
This study investigated the insecticidal activity of parts of Cleistopholis patens against developmental stages of Plodia interpunctella in stored maize grains. The efficacies of the powders as contact and fumigant insecticides were evaluated by admixing different concentrations (0.5, 1.0, 1.5, 2.0 and 2.5g) to maize grains containing developmental stages of the moth. Egg hatchability, adult emergence, larvae mortality and adult mortality of the moth were used as indices of the insecticidal activities at 24hrs, 48hrs, 72hrs, and 96hrs post-treatment periods. The powders from the root bark and stem bark of C. patens completely inhibited egg hatching and adult emergence as both contact and fumigant insecticide. Also, they evoked 100% mortality at 2.5% protectant concentration at 96hrs post-treatment period against larvae and adult P. interpunctella. The leaf powder was the least effective as both contact and fumigant insecticide.

Abstract:
The life cycle stages of Indian meal moth, Plodia interpunctella (H) was studied on four different diets: whole maize flour, whole wheat flour, breadfruit flour and a formulated diet, under ambient laboratory conditions of 28±2oC and 75±5% R.H. The proximate composition of the diets, oviposition, larva instar stages, and the complete developmental duration from egg to adult of the moth were examined on the four different diets. The result showed that the percentage protein value of the formulated diet was significantly higher (14.58) than other diets. The oviposition of the moth on the diets ranges between 1-3 days and about 70% of the eggs laid were on the first day of oviposition in all the diets. The highest number of eggs laid was observed on moths reared on maize flour. Incubation of eggs examined on the diets ranges from 3-4 days. Also, there were variations in the number of larva instar stages in the four diets. The formulated diet recorded the lowest period of pupation (6.33 days) and the total developmental average period (23.50days). The study clearly showed that the formulated diet is suitable for rearing P. interpunctella under laboratory conditions.

Abstract:
The ethanolic and aqueous extracts of the stem-bark of Cleisthopholis patens (Benth) were tested against the larvae and adults of Anopheles gambiae at varying concentrations (10%, 20%, 30%, 40% and 50% for powder, 1%, 2%, 3%, 4% and 5% for oil extract and 10%, 20%, 30%, 40% and 50% for aqueous extract). The ethanolic oil extract of C. patens at 1-5% concentrations had significant effect on larvae and adult of An. gambiae with percentage mortality range of 83-100% within 90mins of exposure periods. The aqueous extract of C. patens was relatively ineffective against the larvae of An. gambiae at all levels of concentrations while the fumigant effect of the powder was slightly effective against adult An. gambiae which achieved 23.30 - 36.70% mortality of the insect. The results obtained showed significant difference when the value of ethanolic extract, the aqueous extract and the powder form were compared (p < 0.05). This shows that the plant oil (ethanolic extract) of C. patens is highly toxic at all concentrations (1-5%) to the larvae and adults of An. gambiae which resulted in the mortality effects.
