“…Hewlett (1947) suggested that intoxication by oil was due to the mechanical action, interfering with breathing by blocking the spiracles. On the other hand, there are authors who believe that toxicity of oils is attributed to chemical action (Singh et al 1978) or may act both physically and chemically in the insect (Obeng-Ofori 1995). For Taverner et al (2001), oils can act in the insect nervous system by increasing the permeability of neuron membrane and thus affecting ion change and stressing excitability of neuron cells.…”

Since 2009, when sulfluramid was listed in annex B of the Stockholm Convention’s Persistent Organic Pollutants, effort has been made to search for other active ingredients to use in baits for controlling leaf-cutting ants in Brazil. Considering that active ingredients that inhibit insect cellular respiration have been shown to be effective in controlling ants, the current work aimed at assessing the toxicity of hydramethylnon to Atta sexdens rubropilosa workers. Hydramethylnon was dissolved in acetone and in a solution of acetone + soy oil then incorporated in artificial diet at concentrations of 1 µg/mL, 5 µg/mL, 10 µg/mL, 100 µg/mL, 200 µg/mL and 1000 µg/mL. The treatments where ants were daily fed on the diet containing hydramethylnon at 100 µg/mL, 200 µg/mL and 1000 µg/mL, especially those dissolved in soy oil, exhibited high mortality in comparison to the controls. The data presented here confirms the insecticidal activity of hydramethylnon and highlights the importance of employing soy oil in the formulation of baits to control leaf-cutting ants because it enhances hydramethylnon efficiency.

“…The precise effect of plant oils (Don-Pedro 1989) on gravid female beetles is still unclear. Nevertheless, oils (Singh et al, 1978;Credland, 1992) have been reported to cause the death of developing embryo through asphyxiation. However, the significantly lower number of the immature stages, adults (total progenies) despite the higher scores in 2010 could be attributed to exit of the weevil following it emergence from the roots.…”

The efficacy of the pre-and post-planting application of neem seed oil (NSO) or/and diazinon and time of harvest for the control of sweetpotato weevil, Cylas puncticollis (Boh.) was evaluated during the 2009 and 2010 cropping seasons. Forty-eight plots of 3 x 4 m 2 each were demarcated and 240 sweetpotato (var. TIS2532.op.1.13) vine cuttings were dipped into 0, 30 and 50 mls NSO and 30 mls of diazinon (60 EC) mixed in 2 and 10 litre soapy water, respectively and kept for 30 mins before planting. Similar treatment was also basally applied post-planting at 1MAP. In 2009, results showed that treatments (NSO or diazinon or their combinations) did not significantly influence percentage plant stand at harvest in both years, but lower percentage plant stands were obtained at 6 MAP (47.72%) than at 5MAP (56.87%). Significantly higher mean total weights of 34.44 t/ha was obtained in 2009 and 8.99 t/ha in 2010 respectively. Similarly, yield ranged from as high as 53.69 t/ha at 5MAP in 2009 to as low as 5.51t/ha at 6MAP in 2010. Significantly lower attributes of C. puncticollis as a pest were obtained in 2009 than in 2010. Treatments significantly suppressed root damage from 68.59% (Pr0Pt0) to 44.38% (Pr3Pt3) at 5 to 6MAP. Time of application was significant as 50 mls of NSO applied pre-and post-planting gave highest (35.30%) control of the pest at harvest.

“…Also, they reported that some of the varieties of pulse grains are more susceptible to insect infestation than others due to inherited characteristics, like, hardness; the major source of storage infestation is from the field, and cross infestation within stored commodities also occurs. Singh et al [14,15] earlier recorded palm and coconut oils at 4 mL/kg were the most effective on chick pea seed against C. chinensis for three months of storage, followed by groundnut oil, rapeseed and mustard oils, sesame, sunflower and soybean oils. Schmutterer [16] and Bekele et al [17] mentioned the properties and potential of pesticides from the neem tree, Azadiractha indica and leaves of Ocimum kilimandscharicum (Labiatae) to control stored products pests.…”

This study was conducted under Laboratory of Plant Protection Department, Faculty of Natural Resources and Environmental Studies, University of Kordofan, Elobeid in Sudan, during March-June 2015 to assess the effect of six treatments on germination of cowpea seeds infested by Callosobruchus chinensis Linn., a serious Coleoptera pest which damages cowpea seeds. The agents used were groundnut oil, wood ash, sand, neem leaves powder, Rabal leaves powder and hot pepper powder. In the lab bioassay, the results obtained due to the infestation by C. chinensis showed that there were highly significant differences (P > 0.01) in the number of holes per 100 cowpea seeds between the different treatments at intervals of one month, and up to the end of the storage period, the numbers of holes per 100 cowpea seeds were 44, 740, 859, 856, 841 and 892 holes in the treatments, respectively. The germination of seeds treated with groundnut oil was 60%, while it was zero for the other treatments. It was concluded that the groundnut oil made creamy coat on the seeds and prevented the development of cowpea beetle infestation. Hence, it can be used by farmers at local levels to protect seeds for cultivation.
