The larvae of scarab beetles, known as "white grubs" and belonging to the genera Phyllophaga and Anomala (Coleoptera: Scarabaeidae), are regarded as soil-dwelling pests in Mexico. During a survey conducted to find pathogenic bacteria with the potential to control scarab larvae, a native Serratia sp. (strain Mor4.1) was isolated from a dead third-instar Phyllophaga blanchardi larva collected fro...

Abstract The resilience of coral reefs is dependent on the ability corals to settle after disturbances. While crustose coralline algae (CCA) are considered important substrates for settlement, it remains unclear whether larvae respond CCA metabolites and microbial cues when selecting sites attachment metamorphosis. This study tested settlement preferences an abundant species ( Acropora cytherea...

Two cases of overwhelming strongyloidiasis complicating psoriasis and systemic lupus erythematosus during corticosteroid therapy were described. Mebendazole 400 mg per day was prescribed for three days in the first case when stool examination disclosed numerous larvae of S. stercoralis. Nine days later, he experienced hemoplYsis. Chest-roentgenogram showed diffuse bilateral pulmonary infIltrati...

The action of crude ethanol extract of the stem bark of the soapberry Magonia pubescens St. Hil. was studied upon larvae of the Brown Dog tick Rhipicephalus sanguineus (Latreille). Tick larvae were obtained by maintaining gravid females in an incubator, after collecting them from naturally infested kennels. The tick larvae were placed in envelopes of filter paper impregnated with different conc...

Viral hemorrhagic septicemia (VHS) is one of the most serious fish viral diseases for cultured rainbow trout (Oncorhynchus mykiss), although VHS virus (VHSV) seems to be ubiquitous among marine fishes. In the present study, VHSV isolation was performed with free-living and cultured turbot (Psetta maxima) in the Trabzon coastal area of the Black Sea to evaluate participation of VHSV in mass mort...

the establishment and survival of seedlings is one of the main objectives of forest management which ensures continues production. the aim of this article is the investigation of dead trees effect on beech and hornbeam seedlings in masal's forests. for this reason, 30 dead trees were selected, and the control trees were selected in four aspects around the dead trees. they were the same as ...

INTRODUCTION The mosquito Aedes aegypti is the principal vector of dengue and yellow fever flaviviruses. Temephos is an organophosphate insecticide used globally to suppress Ae. aegypti larval populations but resistance has evolved in many locations. METHODOLOGY/PRINCIPAL FINDINGS Quantitative Trait Loci (QTL) controlling temephos survival in Ae. aegypti larvae were mapped in a pair of F3 adv...

World Population in 2300 (United Nations 2003b), reporting on the proceedings of a December 2003 expert group meeting on long-range population projections and presenting the results of a new set of United Nations population projections,* bears out Hajnal’s argument. Among his three propositions, the validity of the second is the most obvious. There has been a veritable outpouring of demographic...
