Nisotra is a genus of flea beetles in the family Chrysomelidae. They are found in Africa, Asia, and Australia. There are around 90 described species in Nisotra, including about 70 in Sub-Saharan Africa and Madagascar. Many of these species are agricultural pests.[1][2][3][4][5][6]

Description

[edit]

Nisotra can be recognised by: a thickset and distinctly convex body; the pronotum as wide of the elytra basally; the pronotum anterior margin with two longitudinal groove-like impressions, often deeply impressed and sometimes reaching middle of pronotum.[6]

Diet

[edit]

Nisotra feed on plants in the families Malvaceae, Bombacaceae, Tiliaceae, Fabaceae, Rosaceae, Asteraceae, Lamiaceae, Rubiaceae, Poaceae and Orchidaceae.[7]

Larvae feed on roots (boring in stems has also been reported[8]), while adults feed on leaves.[9]

Pests

[edit]

In the Solomon Islands, N. basselae is a pest on bele (Abelmoschus manihot). Its impact is so severe that bele is no longer grown in many places on the islands.[9]

Nisotra chrysomeloides is a pest on okra (Abelmoschus esculentus). Its abundance varies depending on temperature, relative humidity and rainfall.[10] Another okra pest is Nisotra sjostedti.[11]

Species

[edit]

These species, among others, belong to the genus Nisotra:
