Genetic Distances of Three Mollusk Species Investigated by PCR Analysis
Three species of Nortamea concinua (NC) and Haliotis discus hannai (HDH) from Tongyeong and Sulculus diversicolor supertexta (SDS) are widely distributed on the coast of the Yellow Sea, southern sea and Jeju Island in the Korean Peninsula under the innate ecosystem. There is a need to understand the genetic traits and composition of three mollusk species in order to evaluate exactly the patent ...
متن کاملInteractions among three species of cereal aphids simultaneously infesting wheat
Interactions among greenbug, Schizaphis graminum (Rondani), Russian wheat aphid, Diuraphis noxia (Mordvilko), and bird cherry-oat aphid Rhopalosiphum padi (L.) were examined on wheat plants (Triticum aestivum L., cultivar TAM 107). Nymphs were released on the plants as conspecific and heterospecific pairs of either first or fourth instars and evaluated for survival, developmental time, fecundit...
متن کاملSchistosome/mollusk: genetic compatibility.
Schistosomiasis remains one of the most prevalent parasitic infections and has significant economic and public health consequences in many developing countries. Economic development and improvement in standard of living in these countries are dependent on the elimination of this odious disease. For the control of Schistosomiasis, understanding the host/parasite association is important, since t...
متن کاملDescriptions of Polyps and Epidermal Papillomas in Three Bivalve Mollusk Species
Polypoid growths of the foot, mantle, and pericardium have been found repeatedly in bivalve molluscs. These growths (reviewed by Pauley, 1969; Sparks, 1972) generally are composed of essentially normal tissues and have been variously interpreted. Forty-seven (15.7 percent) of 299 freshwater mussels, Anodonta californiensis, with foot lesions were collected by Gilbert B. Pauley from the Columbia...
متن کاملEfficacy of Three Insecticides on Rat Flea (xenopsylla Cheopis) Infesting Rodents in Giza Governorate, Egypt.
The extensive use of insecticides in public health and agriculture sectors is the main reason for development of resistance in fleas associated in domestic rodents. The present work was planned to investigate the insecticidal efficacy of Lambda-cyhalothrin, Chlorpyrifos and Fenitrothion against rat flea (Xenopsylla cheopis) infesting rodent species in Giza Governorate, Egypt. The lethal concent...
