Native to China and Korea, the Asian longhorned beetle, Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), is a polyphagous wood-boring pest for which a trapping system would greatly benefit eradication and management programs in both the introduced and native ranges. Over two field seasons, a total of 160 flight intercept panel traps were deployed in Harbin, China, which trappe...
A green and convenient protocol is described for the preparation of 1-(alkylamino)-3-(1,3-dioxoisoindolin-2-yl)-2-methyl-1-oxopropan-2-yl benzoates via one-pot three-component reaction between 2-(2-oxopropyl)isoindoline-1,3-dione, an alkyl isocyanide and an aromatic carboxylic acid in water at room temperature. The methods used to follow the reactions are TLC and NMR, which indicated that there...

Two new grapefruit hybrids and their parent cultivars were evaluated by headspace gas chromatographic analysis of fresh juice from the fruit. Quantities of 39 volatile components were determined, and the variation compared to the parent fruit for each component monitored was tabulated. The relatively low amounts of some volatile components in hybrid 2 fruit support the observation that the flav...
Verticillium wilt is a serious disease of pistachio caused by Verticilliumdahliae. Control of the disease is difficult due to soil borne nature of the causal agent. Verticillium wilt has been biologically controlled by Trichoderma spp. In the present study, Trichoderma spp. was isolated from soils of pistachio orchards and their effect was investigated on radial growth of Verticillium dahliae b...
Sensor array with pattern recognition method is often used for gas detection and classification. Processing time and accuracy have become matters of widespread concern in using data analysis with semiconductor gas sensor array for volatile organic compound gas mixture classification. In this paper, a sensor array consisting of four nanostruc‐ tured semiconductor gas sensors was used to generate...
