The laboratory maintenance and rearing of Stimulium damnosum complex species and the cytotaxonomic determination of reared larvae, has been useful to OCP in the following fields of investigation: 1. Species identification of reinvading females. 2. Distribution of biting populations of S. damnosum complex species. 3. Identification of eggs and small larvae found within the OCP area. 4. Host pref...

here we describe a case of ophthalmomyiasis in a male patient with basal cell carcinoma. during the operation several live and motile maggots were removed from the lesion. preliminary examination on the larvae confirmed their affiliation to the genus sarcophaga (diptera: sarcophagidae).this genus is widely distributed throughout the world and species are very difficult to identify. the authors ...

feeding behavior of yellowfin seabream larvae during the first two weeks of larval life was studied by feeding larvae  on different ratios of live food and  microencapsulated diet (med). food consumption rate increased progressively with increasing larval weight. the results from visual observation of the larval guts under a light microscope indicated that yellowfin seabream larvae were able to...

The production of a multiple nucleopolyhedrovirus (SeMNPV) of the beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), has been markedly increased by using juvenile hormone analog (JHA) technology to generate a supernumerary sixth instar in the species. In the current study we compared the incidence of cannibalism in S. exigua fifth and sixth instars reared at low (two larvae per...

during a survey on pistachio, pistacia vera l., pests in isfahan, iran, in 2015, some lepidopteran larvae living and feeding inside galls of the wrinkling pistachio aphid, forda hirsuta mordv., were observed. after laboratory rearing of these larvae, the moths were identified as altenia mersinella (staudinger, 1879) (lep.: gelechiidae) by the third author. this species has previously been repor...

The effects of stocking density of eggs and larvae were studied related to the morphological deformities appearance, percentage of survival, and growth rate, in order to achieve the most suitable stocking density for eggs and larvae in incubators and rearing tanks. The egg stocking densities were 500, 700 and 900 g per incubator for great sturgeon, 500 and 1000g per incubator for Persian sturge...

Spathius galinaeBelokobylskij&Strazanac is a recentlydescribedparasitoidof theemerald ash borer, Agrilus planipennis Fairmaire, in the Russian Far East, and is currently being considered for biocontrol introduction in the United States.

Emergence and survival of adults for 24 hwas compared forTrichogramma chilonis Ishii reared on eggs of Corcyra cephalonica (Stainton) adults whose larval growth and development had beenmonitored on broken grains of four different cereals: Þngermillet (Eleusine coracanaL.Gaertn), softwhitewheat (TriticumaestivumL), short-grainedwhite rice (Oryza sativaL.), anddurra sorghum (Sorghum bicolor L. Mo...

BACKGROUND & OBJECTIVES Biological control through the use of parasitoids and pathogens is one of the alternatives to the use of chemical pesticides for control of insects of public health importance. At the Vector Control Research Centre, a liquid formulation developed using the metabolite of a Pseudomonas fluorescens strain was found to be lethal to larvae as well as pupae of vector mosquitoe...
