“…Our findings that the oil treatment does not affect the nutritive content of cowpea seeds agree with reports by Cruz and Cardona (1981), Hill and Schoonhoven (1981) and Pacheco et al (1995). This further confirms that palm oil treatment would be an acceptable alternative for cowpea protection.…”

A commercially produced palm oil brand, Palmin oil, was evaluated for its effect on eggs and larvae of Callosobruchus maculatus (F.) (Coleoptera: Bruchidae) on cowpea (Vigna unguiculata (L.) Walp. Application of 1 u.1 of the oil on eggs deposited on 10 cowpea seeds, or directly on larvae growing inside seeds resulted in their death. Embryo mortality occurred only when the oil was placed at the anterior end of the egg. The nutritive content of cowpea seeds treated with Palmin oil remained unchanged. Furthermore, the oil did not go rancid following six months of storage.

“…Only a limited number of plants of different families have been studied with respect to their insecticidal potential against Z. subfasciatus. Various plant derived materials have been used to constrain the loss caused by this infestation in stored grains, such as essential oils (14,15), seed oils (16,17) and powders and extracts of different plant parts (18)(19)(20).…”

The essential oils of leaves and stems of Croton grewioides Baill. of the "agreste" region of Pernambuco, Brazil, were obtained by hydrodistillation and analyzed by GC and GC/MS. Twenty-two components were identified, which represented 99.8% and 98.6% of the total constituents in the leaf and stem oil, respectively. Croton grewioides produced an oil with a predominance of phenylpropanoid compounds, whose principal component was (E)-anethole (65.5% in the leaf and 47.8% in the stem). Other major components found in the leaf oil were methyl eugenol (10.6%) and (E)-methyl isoeugenol (4.7%). Other components identified in the stem oil were (E)-methyl isoeugenol (30.0%), cadalene (8.4%) and methyl eugenol (4.6%). The insecticidal activity of C. grewioides was evaluated against Mexican bean weevils, Zabrotes subfaciatus (Boheman) resulting in a LC 50 for the leaf oil, which was 3.4 times less than that obtained from the stem oil.

“…The only oils commercialised for insect control are mineral oils. To date, only a few authors have studied the effect of other oils such as vegetable and fish oils on different insect species 5, 7, 21–26. Furthermore, the effect of these oils in combination with pesticides has not been fully studied.…”

Experiments were carried out in the laboratory to assess the insecticidal effect on Myzus persicae Sulzer of different oils applied alone or combined with imidacloprid or pirimicarb. The oils tested were a horticultural mineral oil, a refined rapeseed oil, a refined soya oil and a raw fish oil. When the oils were sprayed alone on pepper plants infested with M. persicae, mineral oil caused the highest mortality of aphids (over 80%). Applied before aphid infestation of pepper leaves and in mixture with low doses of imidacloprid (at one-fifth of the dose recommended by the manufacturer) and pirimicarb (at one-tenth of the dose recommended by the manufacturer), the oils did not significantly increase the toxicity of the insecticides alone. However, sprayed on aphid-infested pepper plants, the mortality rates achieved by imidacloprid/mineral oil and imidacloprid/rapeseed oil mixtures were significantly higher than those achieved by imidacloprid alone at 16 and 24 h. In a field experiment the effect on the incidence of the potato virus (PVY) of the oils in combination with imidacloprid was determined. Mineral oil, rapeseed oil and soya oil were sprayed eight times onto seed potato plants treated with imidacloprid before sowing. Mineral oil reduced PVY-infected plants by 60% and rapeseed oil by 40% compared with plots treated with imidacloprid. The oils applied as 10 ml litre-1 emulsions in water did not cause symptoms of phytotoxicity on the potato plants, and yield was not reduced.
