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

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

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

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

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