This work aimed to investigate chemical composition of essential oils obtained from Zanthoxylum dissitum leaves and roots and their insecticidal activities against several stored product pests, namely the cigarette beetle (Lasioderma serricorne), red flour beetle (Tribolium castaneum) and black carpet beetle (Attagenus piceus). The analysis by GC-MS of the essential oils allowed the identificat...

Susceptibility of Lasioderma serricorne (F.) (Coleoptera: Anobiidae) Life Stages to Elevated Temperatures Used During Structural Heat Treatments Authors: C. Yu, B. Subramanyam, P.W. Flinn, J.A. Gwirtz Submitted to: Journal of Economic Entomology Methyl bromide is still widely used in food processing and storage facilities for the suppression of storedproduct insect pests, but its use is schedul...

The widespread use of synthetic chemical pesticides beginning in the late 1930s has contributed to development insecticide resistance many important species pest insects and plants. Recent trends pesticide have emphasized more environmentally benign control methods that take into consideration environmental, food safety, human health. Biopesticides (e.g., naturally occurring pesticidal compound...

In this paper we consider contact CR-warped product submanifolds of the type $M = N_Ttimes_f N_perp$, of a nearly Kenmotsu generalized Sasakian space form $bar M(f_1‎, ‎f_2‎, ‎f_3)$ and by use of Hopf's Lemma we show that $M$ is simply contact CR-product under certain condition‎. ‎Finally‎, ‎we establish a sharp inequality for squared norm of the second fundamental form and equality case is dis...

Tribolium confusum and Sitophilus oryzae are stored product pests found worldwide. Environmental damages, human health issues the emergence of resistance driving scientists to seek alternatives synthetic insecticides for its control. Under this scenario, plant secondary metabolites being increasingly studied as bioinsecticides because they renewable, natural, biodegradable, non-persistent in en...
