title: Identification of instars of Hypera postica using chaetotaxy.
abstract: A new method using chaetotaxy for identification of instars of Hypera postica (Gyllenhal) is presented and compared with earlier methods. I recommend a combined method using separation of small (first and second instars) and large (third and fourth instars) followed by identification of particular instars by using chaetotaxy.
