Impact of feeding system and infection status of the blood meal on Ixodes ricinus feeding

Laying hens (29-wk old) had access to a basal diet and one of full-fat soybeans, fish meal or blood meal during a 6-week trial to investigate their preference for different protein sources. There was no effect of the dietary treatment on egg production, egg weight or mortality rate (P>0.05). However, weight loss was different (P<0.05) among the treatments with the largest body weight loss observed in birds offered blood meal.

The Relationship ◽

Very High

AbstractThe egg production of females of Ixodes ricinus (L.) was found to be closely related to the engorged body weight. The relationship was due almost entirely to the size of the blood-meal. Smaller ticks seemed to be slightly more efficient than larger ones in converting their blood-meal to eggs. Ticks, especially larvae, that overwintered in diapause did not survive as well as those that fed and then moulted in the same year. Larvae that fed and entered diapause early in the autumn did not survive as well as those that fed later in the season. A very high proportion of tick eggs hatched, either in the same year as they were laid or after overwintering. Almost all nymphs and adults became active and climbed to the top of the tubes after moulting. Although most larvae appeared to become active, only about half of them reached the tops of the tubes. This is thought to be a reflection on the fact that larvae are adapted to parasitise small rodents. It is suggested that winter temperatures may play an important part in determining the mortality rate of larvae that overwinter in the engorged state.

Hematophagous Arthropods

Abstract Background: Ticks are hematophagous arthropods which normally attach to the surface of the skin of the host for the blood meal. Their aberrant presence in the subcutaneous tissue of few carnivores, predominantly foxes has been reported. However, there are no reports in other carnivores such as mustelids or golden jackals. Our aim was to investigate and broaden the host spectrum for this aberrant localization of ticks.Methods: Between 2015 and 2020, 198 carnivore carcasses from 12 species have been examined by parasitological necropsy. If subcutaneous ticks were found, the nodules were removed, carefully dissected, and stored in ethanol. The identification of the subcutaneous ticks was carried out at the species level.Results: A single subcutaneous tick was found in one sample, a golden jackal and was identified as a female Ixodes ricinus. All other carcasses were negative for subcutaneous ticks.Conclusion: The present paper represents the first report of a subcutaneous tick in a golden jackal (Canis aureus), extends the host spectrum of this unusual phenomenon and demonstrates to date its presence only in canid carnivores.

Abstract. Devkota RP, Subedi JR, Wagley K. 2021. Prevalence of gastrointestinal parasites in equines of Mustang District, Nepal. Biodiversitas 22: 3958-3963. The study was conducted from March 2018 to November 2018 in four villages of Mustang district to find out the prevalence of gastrointestinal parasites in equines (horses and mules). Fecal samples collected from 175 randomly selected equines (105 from horses and 70 from mules) were preserved in 2.5% potassium dichromate and microscopically examined using concentration techniques to detect ova, larvae, and oocysts of parasites. The overall prevalence of gastrointestinal parasites was found to be 84.57% with an incidence rate of 81.90% and 88.57% in horses and mules respectively. The prevalence of gastrointestinal parasites between horses and mules did not vary significantly (p>0.05). Also no significant association (p>0.05) between the prevalence rate of parasites and study areas was observed. Among identified parasites in horses, Strongyles showed the highest prevalence (68.57%) followed by Strongyloides spp. (23.80%), and Parascaris equorum (14.28%) and in mules Strongyles showed the highest prevalence (80.0%) followed by Parascaris equorum (35.71%), Strongyloides spp. (28.57%), and Dictyocaulus spp. (5.71%). Prevalence of gastrointestinal parasites showed no significant variation (p>0.05) with respect to age and feeding status. However, the prevalence rate significantly varied (p<0.05) with respect to parameters like infection status (single and mixed), housing condition and health status. The present study revealed a higher prevalence rate of gastrointestinal parasites due to poor husbandry practices and lack of adequate veterinary services. Therefore, improvement in housing and feeding system, awareness regarding effective regular deworming, and establishment of veterinary hospitals in the study areas were recommended.
