Behavioral Explanations Underlying The Lack Of Trap Effectiveness For Small-Scale Management Of Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Patrick C. Enstrom, Carissa A. Schoenick

Faculty Research & Creative Activity

Traps containing a combination floral and synthetic pheromone lure are used to monitor and manage Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae). One key factor limiting trap effectiveness for beetle control is the "trap spillover" phenomenon, in which the trap attracts beetles without capturing them, resulting in increased damage to surrounding host plants. We investigated the mechanisms underlying trap spillover by conducting two studies in a soybean field in east central Illinois. In the first study, we set up trap stations for 1 d and compared the sex, size, and egg load (for females) of beetles caught in the traps …

Blast Disease Influence On Agronomic And Quality Traits Of Rice Varieties Under Mediterranean Conditions, Spyridon D. Koutroubas, Dimitrios Katsantonis, Dimitrios A. Ntanos, Elizabetta Lupotto

Turkish Journal of Agriculture and Forestry

The effects of Pyricularia oryzae, the causal agent of blast disease in rice, on plant growth, grain yield, and grain quality under Mediterranean conditions were studied in 2002 and 2003. Four rice varieties were grown under high and low disease pressure, achieved by early inoculation with the blast fungus and by natural infection, respectively. Results showed that inoculation affected the overall plant growth and yield and resulted in a reduction in plant height, number of productive tillers per plant, grain weight, and grain yield. The magnitude of the reduction was dependent on the varietals' susceptibility to the disease. Both types …

Physiological And Nutritional Responses Of Chickpea (Cicer Arietinum L) To Salinity, Abdelmajid Krouma

Turkish Journal of Agriculture and Forestry

The aim of this study was to evaluate growth, nodulation, nitrogen fixation, and ionic repartition in 2 chickpea varieties, namely Chetoui and Amdoun, which are grown under salt stress. Inoculated seedlings were grown in a nutrient solution that lacked NaCl (control) or supplemented with 25 or 50 mM NaCl. Whole plant and nodule growth, nitrogen fixation and sodium, and chloride and potassium partitioning were subsequently evaluated. In comparison to Chetoui, Amdoun maintained a high level of whole plant and nodule growth and had a greater nitrogen fixation activity. Nitrogenase activity measurements demonstrated that nodule senescence was more precocious in Chetoui …
