Autor: Joel E. Cohen, Gertrudo S. Arida, James A. Litsinger, Kong Luen Heong, A. T. Barrion, Kenneth G. Schoenly

Publikováno v: Journal of Applied Ecology. 47:593-602

Summary 1. Fallowing, a type of rotation where no crop is grown, deprives insect pests of food. In tropical irrigated rice, it is not known whether fallow periods deplete natural enemy populations and reduce their pest control effectiveness in post-f

Rice is grown on 10% of the arable land worldwide and provides one-third of the total calorie supply for two-thirds of the human population (International Rice Research Institute, 1991; Food and Agriculture Organization, 1992). In the middle to late

Summary 1. Data from a 645-taxa Philippines-wide food web and multiple regression models were used to predict population fluctuations of insect pests in a rice field. Independent variables of pest models included the biomass of rice plants in the fie

PARASITISM AND PREDATION OF YELLOW STEM BORER, SCIRPOPHAGA INCERTULAS (WALKER) (LEPIDOPTERA: PYRALIDAE) EGGS IN TRANSPLANTED AND DIRECT SEEDED RICE

Autor: Merle Shepard, Gertrudo S. Arida

Publikováno v: Journal of Entomological Science. 21:26-32

Incidence of parasitism and predation of yellow stem borer, Scirpophaga incertulas, eggs was monitored in transplanted and direct seeded rice during March, 1984, to February, 1985. Monthly planting using the two crop establishment techniques allowed

Publikováno v: Entomologia Experimentalis et Applicata. 37:149-153

Ovipositor washings and volatiles from virgin female Scirpophaga incertulas (Walker) (Lepidoptera: Pyralidae) were analysed by gas chromatography (GC) linked to electroantennography (EAG). Two EAG responses were observed at retention times consistent
