ザンビア、ルサカ近郊チランガにおけるヌカカの種構成

Species composition and seasonal incidence of the Culicoides spp. were studies using light-trap at Chilanga near Lusaka, Zambia. Twenty-nine species of Culicoides collected in one year's survey period from February, 1986 to February, 1987 and this included five new species. The results obtained by this and related surveys suggested that C. imicola is a complex of morphologically similar species

Ticks found among the Wild Ringtailed Lemurs at the Berenty Reserve, Madagascar

From the facial skins of the 22 ringtailed lemurs (Lemur catta), 184 ticks (Haemaphysalis (Rhipistoma ) lemuris Hoogstraal, 1953) were collected at the Berenty Reserve, Madagascar. Male ticks occupied 93% of the specimen, and the females only 5%. Among the age-sex classes of lemurs, there was no significant difference in the number of ticks. In a group, the rank order among adult males and adult females was not correlated with the number of ticks found around the facial skin

日本新記録のIxodes pavlovskyi Pomerantzev(ダニ目,マダニ科)

雑誌掲載版北海道朝日町岩尾内,旭川市上雨粉,札幌市定山渓の森林でハタズリ法により植生上から未吸血のマダニ類を採集したところ,シュルツェマダニやタネガタマダニに類似した雌雄成虫を発見した.これらの成虫と実験室内飼育で得た幼若虫はシベリア大陸に分布するIxodes pavlovskyi Pomerantzev, 1948と形態が一致したため,北海道からの新記録として報告した.北海道ではライム病が確認されたことにより,その媒介種であるシュルツェマダニを正確に同定する必要がある.I. pavlovskyiは検索表に示した特徴で,類似種のシュルツェマダニとタネガタマダニから区別でき
