Abstract:
Executive Summary
The ladybird beetle family is a significant group of beetles because they play a significant
role in biological control and are key universal predators. Ladybird beetle biodiversity in
Bangladesh hasn't been thoroughly studied geographically. In light of this, the current study
was carried out to investigate the ladybird beetle fauna in different intensive vegetable
growing areas of Bangladesh. Samples were collected from 6 distinct vegetable growing
localities of Bangladesh namely Jashore, Rangpur, Pabna, Jamalpur, Mymensingh and
Narsingdi. Collection surveys were done in these locations at intervals of fifteen days. There
are eight species according to the identification of the specimens which were grouped under
six genera of ladybird beetles. These species include Coccinella transversalis, Coccinella
californica, Coccinella fulgida, Cheilomenes sexmaculata, Menochilus sexmaculatus,
Chilocorus sp., Cycloneda sanguinea, and Brumoides suturalis. Analysis of the numerical
data revealed that C. transversalis, Cheilomenes sexmaculata, and Menochilus sexmaculatus
exhibited high levels of abundance, collected from all surveyed localities. In contrast, the
remaining species demonstrated moderate levels of abundance with the exception of
Coccinella fulgida and Brumoides suturalis those were exclusively collected from the
Narsingdi locality.
