Effect of certain insecticides on the post powder beetle Lyctus africanus Lesne: Effect of certain insecticides on the post powder beetle Lyctus africanus Lesne. in Egypt (Coleoptera:lyctidae). Helal, H.; El-Sebay, Y. (Agric. Res. Cent., Minist. Agric., Egypt). Agric. Res. Rev., Volume Date 1981, 59(1), 147-56 (English) 1983. CODEN: AGRRAA. ISSN: 0374-5252. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Cidial [2597-03-7] (1000 ppm), cytrolane [950-10-7] (1000 ppm), dimecron [13171-21-6] (200 ppm), Meral [95032-17-0] (400 ppm), Supracide [950-37-8] (400 ppm), and San 197 [38260-54-7] (200 ppm) caused 100% mortality of L. africanus 24 h after treatment; cyolane [947-02-4] (1250 ppm) and xylophan [95032-65-8] (25,000 ppm) caused 99% mortality. From the median lethal concns. (LC50), Cidial (LC50 14 ppm) was the most toxic and xylophan (LC50 1320 ppm) was the least toxic. These insecticides were used as solns. in kerosine and applied by brush to the boards. The best residual effect was obtained with xylophan.

Div., CIBA-GEIGY Corp., Greensboro, NC 27409, USA). ACS Symp. Ser., 273(Dermal Exposure Relat. Pestic. Use), 43-61 (English) 1985. CODEN: ACSMC8. ISSN: 0097-6156. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) After reviewing the app. and techniques used in measuring rodent dermal absorption of potentially toxic chems. (esp. pesticides), examples of the absorption of 2-ethyl-6-methylaniline [24549-06-2], CGA-73102 [65907-30-4], and atrazine [1912-24-9] by rats and of the absorption of methidathion [950-37-8] by rats and mice were given using 14C-labeled tracer compds.; mice absorbed methidathion 3 times faster than rats.
