background : the visceral larva migrans (vlm) is a syndrome observed in human infection with helminth larval eggs such as the toxocara spp. that usually infects dogs and cats. among the risk factors involved in the occurrence of vlm, partic­ularly importance of these animal populations, an investigation was carried out for the presence of toxocara spp. eggs in public parks in the city of urmia,...

The susceptibility of Aedes aegypti to temefos was evaluated by means of samples of eggs and larvae from four large counties in the state of Ceará (Fortaleza, Barbalha, Juazeiro do Norte and Crato). The technique standardized by the World Health Organization for tests with larvicides was used. The CL50 of eight samples from populations of Aedes was determined, as were their respective resistanc...

reproductive parameters and ovipositional preference of plutella xylostella were assessed on some mutant genotypes of canola (rgs 8-1, rgs 10-2, rgs 8-13, zar 9-9 and talaye 8-3) and their cultivars (rgs, zar, talaye) under greenhouse condition (21 ± 6 °c, 65 ± 10 rh and a photoperiod of 16l: 8d h). comparison of the reproductive parameters on rgs and its mutant genotypes revealed that mutant g...

a seven-week trial was carried out to investigate the possibility of enriching eggs with vitamin e, inorganic and organic selenium added to the laying hen’s diet and lipid stability of enriched eggs during storage. seventy two hy-line w-36 hens were divided into six equal groups. each groups received one of the treatment diets which included control, 0.4 mg/ kg sodium selenite or selenium yeast...

In recent years, Aedes albopictus (Skuse, 1984) has expanded its distribution globally due to high ecological plasticity. This expansion increased the population’s susceptibility contracting diseases such as dengue, Zika, and chikungunya, among others, which are transmitted by this mosquito species. absence of effective control methods, application sterile insect technique (SIT) is proposed par...

  SUMMARY This study was conducted to shed light on to the factors contributing to fertilizing ability of the caput epididymal spermatozoa. In this content, it should be stated that seminal plasma am! epididymal fluid of most mammalians contains inhibitory factors connected to spermatozoa surface. To do this, components of different regions of mouse epididymis centrifuged and a given volume o...

In the study, susceptibility of twelve Bemisia tabaci (Genn., 1889) (Hemiptera: Aleyrodidae) MEAM1 and MED populations collected from tomato pepper greenhouses in Antalya Province (Türkiye) 2019 2020 to spirotetramat, pyriproxyfen cyantraniliprole were determined. To determine lethal concentrations (LC50) for populations, spirotetramat applied using leaf dipping method second instar eggs, respe...
