(Solanaceae) were investigated for acaricidal, repellent and oviposition deterrent properties against adult two-spotted spider mites (Tetranychus urticae Koch) (Acari: Tetranychidae) under laboratory conditions. Leaf and seed extracts, which were applied in 167,250 and 145,750 mg/l concentrations, respectively (using a Petri leaf disc-spray tower method), caused 98 and 25% mortality among spider mite adults after 48 h. The simple logistic regression analysis showed that the independent variable, an increase in the dose of leaf extract was associated with a significant increase in the death rate of T. urticae females, but an increase in the dosage of seed extracts did not have a significant effect. Using probit analysis and estimating the parameters with a confidence limit of 95%, we determined the LC50 values of leaf extract to be 70,593 mg/l. According to Pearson's chi(2) test, mites showed the strongest run off to bean leaf surfaces sprayed with both leaf and seed extracts (in sub-lethal doses: < 7,500 mg/l and < 25,000 mg/l, respectively) and moved towards surfaces that had not been sprayed with extracts. Furthermore, repeated measures ANOVA indicated a significant difference between the number of eggs laid on unsprayed bean leaves compared to bean leaves that were sprayed with leaf and seed extracts at sub-lethal doses, 2,500 and 25,000 mg/l concentrations, respectively. These results suggest that D. stramonium extracts could be used to manage the two-spotted spider mite.eninfo:eu-repo/semantics/openAccessAcaricidalOviposition deterrentRepellentSpider miteThorn apple2-spotted spider-miteAzadirachtinResistanceEntomologyAcariAraneaeDatura stramoniumMagnoliophytaSolanaceaeTetranychidaeTetranychus urticaeAcaricideAngiospermEstimation methodLaboratory methodLeafMiteOvipositionPest controlPlant extractRegression analysisRepellentVariance analysisWeedArticle0002771459000142-s2.0-77951878437173180832EntomologySitophilus Zeamais; Callosobruchus Maculatus; Fumigants
