Quality control procedures for Bactrocera philippinensis Drew & Hancock 1994 (Diptera: Tephritidae) used in sterile insect technique (SIT) programs were established in the mass rearing facility at the Philippine Nuclear Research Institute. Basic studies on pupal irradiation, holding/packaging systems, shipping procedures, longevity, sterility studies, and pupal eye color determination in relati...

germination response to temperature is different among plant seeds. germination rate and percentage is maximal at optimum temperature (s), and then reach to zero at base and ceiling temperatures. the objective of this research was (1) to evaluate germination response of snail medic seeds to temperature and (2) to determine cardinal temperatures of germination rate and percentage. therefore, see...

Nearest neighbor spatial analysis was used to assess the effect of systemic rust caused by Uromyces scutellatus on stand density of Euphorbia esula/virgata , a highly invasive deep-rooted perennial weed of rangelands and natural areas in North America. ANOVA applied to nearest neighbor measurements within four pairs of stands in close proximity, with and without rust, in Hungary and Austria ind...
