Abstract
Taxonomic identification and classifications of insect pest genera
Chrysodeixis
and
Ctenoplusia
of the subfamily Plusiinae is very compulsory due to their phytophagous nature and potential to damage the cash as well as cereal crops. Taxonomy plays a key role in proper not only in identification and classification of the pest but also in designing a successful managing strategy. In current study, specimens of
Chrysodeixis
and
Ctenoplusia
genera were collected from different geographical areas of south Punjab, Pakistan and their diagnostic features were examined following taxanomic keys. The data of temperature, relative humidity and rainfall were also recorded during the study period. Genitalia was extracted by dissecting of the abdomen and inspected under Stereo microscope. The results revealed two new species,
Chryodeixis maxus
and
Ctenoplusia oleraceaus
, from south Punjab region in addition to previously reported species:
Chrysodeixis furihatai
. Suitable management of the voracious insect pest at appropriate time may help in sustaining the agriculture in Pakistan.
