Three new species of braconid wasps from Costa Rica are described here: Allorhogas crinitus reared from leaf galls on Protium panamense (Burseraceae), Allorhogas lacuna reared from galls on Melastomataceae and Allorhogas triopsis reared from fruit galls on Psychotria (Rubiaceae). These new species are diagnosed and compared with other species in the genus. These are the first records of an Allorhogas species associated with the plant families Burseraceae and Rubiaceae. It is the third association of Allorhogas with the family Melastomaceae.

A new plant-feeding species of braconid wasp Allorhogas minimus Centrella & Shaw is described from Heredia Province in Costa Rica. The new species is diagnosed and compared with other species in the genus. This is the first record of an Allorhogas species from fruit galls on Miconia longifolia.

Feeding performances of 3509 male and 4838 female sandflies, Sergentomyia ingrami, fed on 46 native or indigenous and exotic or introduced species belonging to 21 families of plants found in Kenya were examined. The results indicated more feeding on certain families than on others. The most used families were Musaceae, Araceae and Compositae, while the least was Alliaceae. A liking for certain species was also detected in families with more than one species investigated. Generally, the most used species were Bidens pilosa (Compositae) and Lycopersicon esculentum (Solanaceae). Interaction between the sex of the sandflies and the tested plants was minimal, suggesting that in most cases males and females had similar species likings. Sergentomyia ingrami fed more on two of the exotic species investigated.

The ability of a Kenyan sandfly species, Sergentomyia ingrami, to feed on various species of native or indigenous and exotic or introduced plants of Kenya was investigated using the Anthrone test. Some flies contained more sugar than others when they were tested after exposure to the plants.
