Abstract
Nidification of Centris (Hemisiella) tarsata Smith (Hymenoptera, Apidae, Centridini) in trap nests in Northeast Maranhao, Brazil. This work had as objective to obtain ecological data of Centris (Hemisiella) tarsata Smith's nidification in three ecosystems: riparian forest (MC), mesophitic forest (MM) and eucalyptal (EC), using trap nests made by bamboo canes, distributed in differentiated heights: 1,5 m and 5-12 m high. A total of 41 nests were collected: 31 in EC and 10 in MM, the majority in the upper strata and with the largest frequency of nesting occurring in the dry season. The sex ratio was of 1.9:1 (females/ males) in EC and of 1.08:1 in MM. About 22% of nests of the EC and 40% of MM were parasitized by Mesocheira bicolor (Fabricius 1804) (Hymenoptera, Apidae) and Coelioxys sp. (Hymenoptera, Megachilidae). The pollinic analyses showed a higher quantity of pollen grains of Banisteriopsis sp. (Malpighiaceae) and Cassia sp. (Caesalpiniaceae) in EC area and a species of Caesalpiniaceae Kunth. and Banisteriopsis Robinson in MM area.
