Pithitis smaragdula (F.) is a bright green, small carpenter bee which is widespread in the oriental region and is known to pollinate economically important plants, especially legumes and cucurbits. About 300 bees imported from Ludhiana, India, were released 10 April 1969, at Davis, California. Subsequent collecting during the 1st season confirmed that one or more generations of the bees had been reared and that Trifolium repens L. was visited for pollen. Although the overwintering bees under… Expand
Notes on the Nesting Biology of the Small Carpenter Bee Ceratina smaragdula (Hymenoptera: Apidae) in Northwestern Pakistan
Abstract The nesting biology and some foraging activities of the familiar, brilliant metallic green, small carpenter bee Ceratina (Pithitis) smaragdula (F.) (Hymenoptera: Apidae) is documented fromExpand
Effects of introduced bees on native ecosystems
Negative impacts of exotic bees need to be carefully assessed before further introductions are carried out. Expand

Range Expansion of the Small Carpenter Bee Ceratina smaragdula across the Hawaiian Archipelago with Potential Ecological Implications for Native Pollinator Systems1
A comprehensive synthesis of C. smaragdula's known biological and ecological history, as well as a population genetic analysis of this nonnative pollinator, reveal a lack of genetic structure between Hawaiian and native range populations. Expand
Consequences of Introduced Honeybees Upon Native Bee Communities
Evidence is provided that Apis competitively suppresses a native social bee known to be an important pollinator, with the potential for cascading effects on native plant communities. Expand
Bees of the Hawaiian Islands, Exclusive of Hylaeus (Nesoprosopis) (Hymenoptera: Apoidea)
Four other species (Ceratina arizonensis Cockerell (Apidae), Xylocopa sonorina, Lasioglossum impavidum (Sandhouse) (Halictidae) and Megachile gentilis) are adventive arrivals from the western North American fauna. Expand
Nests of Ceratina, Pithitis and Braunsapis from India (Hymenoptera : Anthophoridae)
Abstract Nests of Ceratina propinqua Cameron and Pithitis smaragdula (F) consist of burrows in pithy stalks, each containing a series of brood cells (the oldest below), separated by pith partitionsExpand
Taxonomy and ecology of Ceratinini of North Africa and the Iberian Peninsula (Hymenoptera: Apoidea)
A key, synonymy, descriptions and distributions are given for twelve species of Ceratina (Euceratina), including three new species, C.dallatorreana, shown to reproduces probably entirely by thelytoky and thus is unique among Apoidea. Expand
Chemistry of the mandibular gland secretion of the Indian beePithitis smaragdula
The mandibular glands of the stem-nesting Indian beePithitis smaragdula contain a mixture of salicylaldehyde, citronellyl acetate, geranyl acetate, pentadecane, heptadecane, ethyl tetradecanoate, andExpand


Biological Studies on Ceratina dallatorreana, an Alien Bee in California Which Reproduces by Parthenogenesis (Hymenoptera: Apoidea)
The life history in California is reconstructed by using the structure and contents of the nests, the immature stages, and certain anatomical features of the females, including the amount of wing wear, contents ofthe gut and spermatheca, development of the ovaries, presence of follicular relics, and the condition of the fat body.

The Feasibility of Introducing Squash Bees (Peponapis and Xenoglossa) Into the Old World
The present article discusses the question of introducing to the Old World from the New certain species of “squash bees”, so called because they are especially adapted for pollinating squashes and other species of Cucurbita (gourds, pumpkins and vegetable marrows). Expand
Alfalfa Pollinators with Special Reference to Species Other than Honey Bees
The subject of alfalfa pollination was reviewed recently by Bohart (1957) and the paper emphasizes the activities of al falfapollinators (especially the wild ones) rather than plant responses. Expand
Bees are essential: Pollination of squashes, gourds and pumpkins
Squash and related plants of the genus Cucurbita are monoecious, having both male and female flowers on the same plant, and bees are the major pollinators. Expand
A perliminary revision of the Oriental species of the genus Ceratina (Hymenoptera, Apidae)
The Oriental bees of the genus Ceratina Latr. are difficult to identify. Until now our knowledge of these insects consisted mainly of a considerable number (about 90) of isolated descriptions,Expand
