Kastor çöplerinden (Hymenoptera, megachilidae) yuva yapan ve soliter bir arı türü olan megachile (Callomegachile) cephalotes Smith' in yuva biyolojisi

Bu çalışmada Megachile (Callomegachile) cephalotes Smith' in yuvalanma biyolojisi, yuva yeri, yuvanın yapısı ve başlangıç aşamaları dahil olmak üzere anlatılmaktadır. Dişi an, yalnızca çamur ve ağız salgıları kullanarak ve kastor çubuklarının boğum yerlerini çaprazlama yerleştirerek yuva adacıkları oluşturmaktadır. Akdarı samanlanyla birleştirilen bu çubuklar bir kulübenin tepesine yığılmaktadır. Grubun larva filojenisi üzerine yapılan kısa bir gözlem, bunların ikinci larval, son larva ve pupa dönemlerine ilişkin taksonomik tanımlara uyduğunu göstermektedir. Soliter arı türleri Hindistan'ın kuzeyinde ve ona kesimlerinde hayli yaygındır ve bu türe mensup arılar gerek ziraii gerekse yabani birçok bitkiyi sıkça dolaşmaktadır.

Nesting biology of megachile (Callomegachile) cephalotes Smith, a solitary bee that nests in castor sticks (Hymenoptera, megachilidae)

Nesting biology of Megachile (Callomegachile) cephalotes Smith is described including features of nesting site, nest structure and immature stages. The female constructed haphazardly overlapped nest chambers, over-crossing the node and internode region in vacated pith of castor sticks exclusively using gravel mud mixed with oral secretions. These sticks tied with straws of Pearl millet, were thatched on a hut. A brief larval phylogeny of the group follows the taxonomic descriptions of second instar, postdefecating larva and the pupa. The solitary bee species is quite widely distributed all over north and central India and significantly visits many cultivated and wild crops.
