No R. hibericus was detected on any live-trapped bird. Blood meal analysis of questing adults confirmed the prominent role of the Algerian mouse as the feeding source for nymphs but also revealed that they can also feed on other unidentified hosts, such as the red kite (Milvus milvus Linnaeus (Accipitriformes: Accipitridae)).

Epidemiological studies in alpacas are necessary to determine the magnitude and distribution of lice infestation, which would assist in the implementation of control measures. The aim of this study was to determine the prevalence of lice infestation in newborn and young alpacas (crias) from the provinces of Canchis and Espinar, located in the southern Peruvian Andes. Veterinarians examined a total of 383 alpaca crias less than 6 months of age to diagnose lice infestation. Lice were collected and preserved in 80% ethanol for morphological diagnosis.

This study evaluated the risk factors for flea parasitism in dogs and cats from urban (Ur) and rural (Ru) households in Puerto Iguazú, Argentina, through seasonal sampling between March 2017 and February 2018. Prevalence (P), mean intensity, and mean abundance of the host-associated variable were calculated. To identify associations between the presence/pseudoabsence of fleas and the explanatory variables, a generalized linear mixed model was constructed. A total of 1932 fleas, identified as Ctenocephalides felis felis (Bouché) (Siphonaptera: Pulicidae), were collected from 402 dogs (P<sub>Ur</sub> = 79.8%; P<sub>Ru</sub> = 88.4%) and 87 cats (P<sub>Ur</sub> = 77.6%; P<sub>Ru</sub> = 66.7%). The prevalence was higher in rural dogs. Regarding host species, the prevalence in dogs was higher than in cats in rural areas. Tunga penetrans L.

Risk factors for C. f. felis presence in dogs included young age, lack of antiparasitic treatment, peridomestic fumigation, bare soil and lower humidity and temperature four weeks prior to sampling (w-4). In cats, infestation was associated with young age, the presence of infested dogs in the same household, and higher vegetation coverage. In both hosts, T. penetrans infestation was positively associated with no antiparasitic treatment, lower humidity in w-3, and higher humidity in w-1 and higher temperature in w-2. The findings indicate that the factors influencing the presence, prevalence and abundance of C. f. felis and T. penetrans may differ according to host, socio-environmental, climatic and soil conditions in each locality.

This study aimed to investigate the prevalence, species composition and infestation levels of ectoparasites in dromedaries from different camel herds (CH) across northern Algeria's Sahara Desert. Additionally, we assessed the effects of CH and camel age and sex on parasite loads and infestation patterns regarding the host's affected body region. A total of 68 camels out of 135, randomly selected from four herds CH1-CH4, were surveyed for ectoparasites. Ectoparasites were counted, collected and identified in the laboratory. Pearson correlation tests were employed to analyse the relationship between parasite indices. Similarity analysis was conducted to compare ectoparasite species composition among the sampled CH. The overall infestation level of ectoparasites across the CH was 61.76% with 511 ectoparasite individuals identified. Significant regional variation in tick prevalence was observed: CH1 (88.24%), CH2 (64.71%), CH3 (58.82%) and CH4 (35.29%) (p < 0.001). The most prevalent ectoparasites were ticks, with four species identified: Hyalomma dromedarii Koch (Ixodida, Ixodidae) (45.21%), Hyalomma marginatum marginatum Koch (Ixodida, Ixodidae) (18%), Rhipicephalus sanguineus sensu lato Latreille (Ixodida, Ixodidae) (7.63%) and Ixodes ricinus Linnaeus (Ixodida, Ixodidae) (4.9%). In addition, one mite species Sarcoptes scabiei Linnaeus (Sarcoptiformes, Sarcoptidae), one flea species Ctenocephalides arabicus Jordan (Siphonaptera, Pulicidae) and one fly species Wohlfahrtia magnifica Schiner (Diptera, Sarcophagidae) were identified. Similarity analysis showed a 70% overlap in ectoparasite species composition between herds, suggesting common environmental and management-related risk factors. Overall, the abdomen exhibited the highest percentage of ectoparasites at 22.7%, followed by the neck and sternum (17.8%), and the anal and tail area (17.4%). Adults accounted for 86.1% of infestations, with notable contributions from the abdomen (17.0%) and neck/sternum (15.9%), while young camels made up only 13.9%. The high ectoparasite infestation level, particularly ticks, underscores the need for a comprehensive control plan, especially in herds managed under extensive or nomadic systems.

Coincidentally, three significant livestock disease outbreaks caused by viruses associated with Africa or other tropical regions were first detected in the Netherlands (bluetongue virus serotype 8 (BTV-8), 2006, and BTV-3, 2023) and in western Germany about 200 km from the Netherlands border (Schmallenberg virus, SBV, 2011). This study aimed to determine whether Culicoides biting midges (Diptera: Ceratopogonidae), the vectors of BTV and SBV, are present within flower-packaging plants in East Africa, and therefore whether Culicoides could be unknowingly exported during the shipping of cut flowers. Field sampling was undertaken at a flower-packaging facility in Kenya, East Africa. The facility undertook all stages of cut flower production from maintaining rootstock through to packaging and shipping to an airport for international export. Trapping was undertaken at each stage of production (rootstock, propagation, inside growing greenhouses, in the packing-house, inside cold-storage rooms, during transportation) using Centers for Disease Control and Prevention (CDC) Light Emitting Diode (LED) light traps. Hand-held aspirators were used to obtain individual insects directly from flowers and around composting sites, while emergence traps studied insect emergence from compost, leaf litter and flowers discarded at quality control checkpoints. A maximum nightly catch of 269 Culicoides was identified on a half-acre smallholding, containing 15 ruminants and 40 birds, located 20 m from the nearest greenhouse. The greatest numbers of Culicoides were trapped at a pond (n = 23) and leaf-litter compost site (n = 19) within the curtilage of the flower-packaging plant. Of the seven greenhouses sampled, three had Culicoides trapped overnight (mean = 4, range: 1-9), and no Culicoides were trapped in the propagation units. No Culicoides were trapped in the pack house, cold-store, or during transportation of the flowers to the airport for shipment. No Culicoides emerged from emergence traps or were trapped when aspirating directly from flowers. This is the first study to investigate whether Culicoides are present within flower packaging plants in Africa. The results highlight that although present in small numbers both outside and within greenhouses, the presence of Culicoides declined with each stage of production.
