This study was aimed to gain knowledge on the ontogeny of digestive enzymes in common carp larvae at the governmental Warm water Fish Aquaculture Center of Shahid Rajaee in Sari, Mazandaran, Iran. The ontogenetic development of pancreatic (trypsin, chymotrypsin, lipase and α-amylase) and intestinal (alkaline phosphatase and aminopeptidase-N) enzymes were assessed in common carp larvae from firs...
Protease inhibitors confer resistance in plants against insect pests by inhibiting larval gut proteases. Cultivars of Dolichos biflorus were screened for their inhibitory activity against midgut proteases of Pieris brassicae larvae. Seed extracts of developing and germinating seeds of HPK4 cultivar inhibited larval gut proteases of Spodoptera littoralis efficiently. Neonate larvae of P. brassic...
A total of 1,600 specimens, consisting of 16 different species of marine fish, were dissected and examined for anisakid larvae and adults in visceral organs, abdominal cavity, and muscles. One species of adult-stage nematode was found in two of 16 species of marine fish studied, Johnius carouna and Dendrophysa russelli. No anisakid larvae (third-stage) was found in any of the 16 species of mari...
Heavy metals are a major environmental problem and have caused serious concerns because of characteristics of carcinogenesis, non-degradability and biological accumulation. Major part of this material is absorbed by plants and leads to inactivation of some enzyme, decreased protein production and disrupting variety of reactions and many cellular functions and growth and development cessation. T...

Infective third-stage larvae of three spiruroid nematodes, Ascarops strongylina and Physocephalus sexalatus of pigs and Spirocerca lupi of dogs, were recovered from 14 species of coprophagous beetles belonging to 4 different genera. These larvae were fed to rabbits and/or guinea pigs to study their development in these experimental hosts. Larvae of A. strongylina reached the adult stage in all ...
Juvenile hormone (JH) plays a vital role in the growth, development, and reproduction of insects other arthropods. Previous experiments have suggested that BmFAMeT6 could affect duration silk moth’s larval stage. In this study, we established overexpression strain knockout using GAL4/UAS binary hybrid system CRISPR/Cas 9 system, respectively, found stage was shorter, while longer. Our results e...
Insect vectors are required for the transmission of many species of parasitic nematodes, but the mechanisms by which the vectors and nematodes coordinate their life cycles are poorly understood. Here, we report that ascarosides, an evolutionarily conserved family of nematode pheromones, are produced not only by a plant-parasitic nematode, but also by its vector beetle. The pinewood nematode and...
