an investigation was carried out during april to december 2000 to study mosquito fauna and ecology in guilan prov ince of northern iran. the mosquito larvae were collected by dipping method and larval habitat characteristics recorded ac cording to hydro-ecological features. in total, 3937 larvae of the genus culex from 92 larval breeding sites were collected. six spe cies of the genus culex; cx...

hydatid disease, caused by echinococcusgranulosus, is a common parasitic infection of the liver. disseminated intra-abdominal hydatid disease may occur with the rupture of the hydatid cyst into the peritoneal cavity, producing secondary echinococcosis. but primary hydatid cyst in the pelvis is rare. we report a case of bilateral hydatid cyst of the pelvis in a 53years old woman presented with a...

Strongyloidiasis is an infectious disease caused by the Strongyloides stercoralis larvae, which penetrate the skin, go through the lymphatic circulation, and migrate to the lungs before reaching the intestines. They mature and may cause cutaneous strongyloidiasis, known as larva currens because of the quick migratory rate of the larva. The authors describe a case in which the larvae did not fol...

Eriopis connexa (Germar) (Coleoptera: Coccinellidae) occurs in several countries of South America and its mass rearing is important for biological control programmes. This work evaluated biological aspects of E. connexa larva fed on eggs of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) and Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) frozen for one day, fresh eggs of Dia...

BACKGROUND Bivalves comprise around 30,000 extant species and have received much attention for their importance in ecosystems, aquaculture and evolutionary studies. Despite the increasing application of real-time quantitative reverse transcription PCR (qRT-PCR) in gene expression studies on bivalve species, little research has been conducted on reference gene selection which is critical for rel...

we report a case of human nasal nosocomial myiasis in a 69-year-old rural man with numerous live maggots in nostrils. the patient was admitted in emergency ward due to dyspnea. after 72 hours the companion of patient discovered larva. the presence of the third instar larva indicated that the infestation was not more than three days. the collected instars were cleared, fixed and morphological st...

We have used silkworms, larva of Bombyx mori, to investigate host-pathogen interactions. Silkworms have several advantages, such as high availability of a large number of animals and ease of injection of quantitative amounts of samples. Human pathogenic bacteria such as Staphylococcus aureus, Streptococcus pyogenes, or Pseudomonas aeruginosa kill silkworms. In this review, I would like to summa...

erythraeus (zaracarus) coleopterus mortazavi, hajiqanbar & saboori, 2012 (acari: parasitengona: erythraeidae) was described based on a single specimen from kerman province, southeastern iran, associated with a scarabaeid beetle, cyphonoxia sp. (coleoptera: scarabaeidae). this species reports for the second time from stored grain (off host) in saqqez and baneh cities, kurdistan province, western...

The African fig fly, Zaprionus indianus, is recorded for the first time from Jordan. Samples of this fly were collected from heavily infested dates (Madghool variety) from a farm in the central Jordan Valley. In addition, it was reared in the laboratory on apricots, cherries and figs. Our preliminary observations, photographs for the adult insect, larva and pupa are presented. The pest distribu...

This study was carried out of the region of Monastir in Central Tunisia, between July and August 2010. Larvae were collected using a floatation technique with magnesium sulfate in mud samples. The fourth instar larva of Culicoides cataneii Clastrier, 1957 and Culicoides sahariensis Callot, Kremer, Bailly-Choumara, 1970 are described, illustrated and drawn. Measurements of instars IV are also pr...
