The presence of ectoparasites in animals creates a multitude of health risks to both the host animals and to the humans who come in contact with these animals. This study aims to conduct an ectoparasite survey among those quarantined animals in a wildlife rescue center and determine the distribution of the ectoparasites in their hosts. Acetate strip technique and manual extraction methods were employed to collect the ectoparasites from the animals brought in the wildlife rescue center. About 53% of the quarantined animals in the wildlife rescue center were positive for ectoparasitic infestation. A total of 344 ectoparasites were recovered from 51 birds and 6 mammals quarantined in the wildlife rescue center. Of the total ectoparasites, 23 are lice and 321 are mites. The ectoparasites obtained from the survey showed that the isolated ectoparasites belong to 11 different taxa. No statistical significant differences were observed on the Shannon Wiener Diversity Indices across all the 8 weeks of collection (p > 0.05).

This article discusses the impact of dual-frequency method of EHF radiation of millimeter range on seed crops. The essence of the dual-frequency method is the selection of biologically active frequency, which tends to change in a narrow range and simultaneous processing of seeds to several biologically active frequencies. Results of laboratory and field studies in Tat NIISH show the positive impact of two-frequency method and a more effective stimulant effect.

Study of Single and Combination Application of Cover Crops and Their Removal Time on Weed Suppression in Sugar Beet Fields

by Seyyed Mahdi Hoseyni and Hossein Najafi

Original Research

In order to study the effect of different combinations of cover crops and time of their removal on weeds population in sugar beet fields, an experiment was conducted at the Iranian Research Institute of Plant Protection, . The study was based on two factorial experiments with randomized complete blocks design with four replications. Treatments in first experiment were type of cover crop including: 1) X Triticosecale wittmack, 2) Hordeum vulgare, 3) Trifolium alexandrium), 4) Raphanus sativus and removal times including: 1) at four-leaf sugar beet stage, 2) at eight-leaf stage of sugar beet. In the second experiment, different combinations of cover crops were evaluated. Treatments were cover crop combination including: 1) Hordeum vulgare & Raphanus sativus, 2) X Triticosecale wittmack & Raphanus sativus, 3)Hordeum vulgare & Trifolium alexandrium, 4) X Triticosecale wittmack & Trifolium alexandrium and removal time of cover crops (as the same of the first experiment). The results showed significant effects of different cover crops and their removal times on weeds dry weight and population. Between treatments, combination of X Triticosecale wittmack & Trifolium alexandrium had the lowest weed dry weight and population when removed at four-leaf stage of sugar beet.
