Insecticide Toxicity, Synergism, And Resistance In The German Cockroach (Dictyoptera: Blattellidae), Jeffrey G. Scott, Donald C. Cochran, Blair Siegfried Oct 1990

Insecticide Toxicity, Synergism, And Resistance In The German Cockroach (Dictyoptera: Blattellidae), Jeffrey G. Scott, Donald C. Cochran, Blair Siegfried

Department of Entomology: Faculty Publications

The toxicity of, synergism of, and resistance to insecticides in four strains of German cockroach, Blattella germanica (L.), were investigated. Toxicity of nine insecticides by topical application to the susceptible strain varied >2,000-fold, with deltamethrin (LD50 = 0.004 μg per cockroach) and malathion (LD50 = 8.4 μg per cockroach) being the most and least toxic, respectively. Resistance to pyrethrins (9.5-fold) in the Kenly strain was unaffected by the synergists piperonyl butoxide (PBO) or S,S,S-tributylphosphorotrithioate( DEE), suggesting that metabolism is not involved in this case. Malathion resistance in the Rutgers strain was suppressible with PBO, implicating oxidative metabolism as …

Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble Aug 1990

Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the third and most comprehensive study of pesticide use on crops in Nebraska. The first was completed in 1978 and the second one in 1982. The first study indicated that approximately 25 million pounds (11.34 million kg) of active ingredients were used on the major crops in Nebraska. This increased to approximately 30.2 million pounds (13.7 million kg) in 1982. The USDA requires accurate information to meet their responsibilities. Thus, this survey was undertaken to determine: 1) the use of pesticides on crops, pasture and rangeland and 2) to identify pest management practices.

Feeding Behavior Of Nephotettix Virescens (Homoptera: Cicadellidae) On Rice Varieties With Different Levels Of Resistance, H. R. Rapusas, E. A. Heinrichs Jun 1990

Feeding Behavior Of Nephotettix Virescens (Homoptera: Cicadellidae) On Rice Varieties With Different Levels Of Resistance, H. R. Rapusas, E. A. Heinrichs

Department of Entomology: Faculty Publications

The feeding behavior of Nephotettix virescens (Distant) on rice varieties with different levels of resistance was studied using an AC electronic monitor for insect feeding (EMIF) system. Varieties used were TN1 (susceptible), IR36 (moderately resistant), and ASD7, IR60, and IR64 (resistant). Six typical waveforms were recorded, and each type corresponded to a certain activity of the insect during the feeding process as indicated by histological sections of the leaf observed. Significantly more phloem feeding was observed on the susceptible plants than on the moderately resistant and resistant plants. Fifty percent of the total test period was spent feeding on the …
