Rice paddy fields are important habitat for many dragonfly species. In Japan, populations of dragonflies inhabiting rice paddies, in particular Sympetrum (Odonata: Libellulidae), have decreased greatly the last few decades. A major cause decline has been suggested to be use systemic insecticides (e.g., phenylpyrazole and neonicotinoid) nursery boxes seedlings. this study, we examined effects ch...

Aspects of Biosteres arisanus (Sonan) (= Opius oophilus Fullaway) (Hymenoptera: Braconidae) development on the oriental fruit fly, Bactrocera (= Dacus) dorsalis (Hendel), were investigated to facilitate mass production in the insectary. Life table statistics were generated for cohorts of B. arisanus females. Overlap in the emergence of fruit flies and parasitoids necessitated a procedure for se...

BACKGROUND The administration of short-acting opioids before emergence is useful for preventing emergence cough induced by an endotracheal tube. This study examined the clinically effective dose of alfentanil for suppressing cough during emergence from desflurane anesthesia. METHODS Twenty-nine adult patients undergoing elective oral surgery were enrolled in this study. During emergence from ...

The date that yellow-bellied marmots (Marmota flaviventris) emerge at a site in Colorado has been used as evidence that climate is affecting hibernating species. Over 6 springs, and at 16 marmot groups, the date of 1st emergence of males, females, and the group as a whole was recorded. Emergence date of males was a function of the number of males in a group (a metric of reproductive competition...
