Fopius ceratitivorus Wharton is the most recently imported parasitoid for biological control of tephritid fruit flies in Hawaii. In this paper we summarize current progress on studies of this parasitoid under quarantine conditions in Hawaii. Tests on its potential target host range reveal that F. ceratitivorus attacks and completes its development only in the Mediterranean fruit fly, Ceratitis ...

A previous study reported the cloning of a putative Prevotella nigrescens-specific DNA probe, Pn23, using random shotgun method. The present study evaluated the species-specificity of Pn23 for P. nigrescens using the clinical strains of Prevotella intermedia and P. nigrescens to develop Prevotella nigrescens-specific polymerase chain reaction (PCR) primers. The specificity was tested against 10...

In his monograph of the genus Medetera, Kowarz (1878) described Medeterus glaucellus based on specimens from Italy and Austria collected by Mik, and from Romania collected by himself. He noted the resemblance to M. muralis Meigen, 1824, since both species lack dorsal setae on the mid tibia, and distinguished his new species by the white lower postocular setae and the white setae on the propleur...

In 1943 AMLONG (1) reported an increase in the transpiration of Cooper's Ernite tomato plants grown from seeds that had been soaked for 24 hours in a solution containing 100 mg. of potassium naphalene acetate, 100 mg. of ascorbic acid and 2000 mng. of thiourea per liter of water. Three years later, BROWN (2) investigating the effect of 2,4-Dichlorophenoxyacetic acid (1000 p.p.m.) on the water r...

The host-feeding patterns of Anopheles quadrimaculatus Say and Anopheles punctipennis (Say) were examined in order to evaluate their potential contributions to the transmission of eastern equine encephalitis virus (EEEv) and other arboviruses in the northeastern U.S.A. Engorged mosquitoes of the two species were collected from EEEv foci in central New York (NY) and throughout New Jersey (NJ), a...

We propose a theory of international agreements on product standards. The key feature of the model is that agreements are viewed as incomplete contracts. In particular, these do not specify standards for products that may arise in the future. One potential remedy to contractual incompleteness is a dispute settlement procedure (DSP) that provides arbitration in states of the world that are not c...

Zebrafish embryos exhibit spontaneous contractions of the musculature as early as 18-19 h post fertilization (hpf) when removed from their protective chorion. These movements are likely initiated by early embryonic central nervous system activity. We have made the observation that narrowminded mutant embryos (hereafter, nrd(-/-)) lack normal embryonic motor output upon dechorionation. However, ...

A sesquiterpene lactone 1-β,10-Epoxy-6-hydroxy-1,10H-inunolide (K100) was isolated through "bioassay-guided fractionation" from Cota palaestina subsp. syriaca, an Eastern Mediterranean endemic plant. K100 inhibited endotoxin- (ET-) induced proinflammatory markers: IL-6, MMP-9, and NO in normal mouse mammary SCp2 Cells. Molecular docking in silico suggested that K100, having highly analogous str...

Chinese hamster cell strains in the early passages in culture display wide variation in number of nucleolus-like bodies per cell, though such strains are characteristically euploid. A variety of criteria indicate that the nucleolus-like bodies are true nucleoli. Their Azure Band fast green-staining properties indicate the presence of RNA and protein; they have typical nucleolar fine structure, ...
