Schistocerca gregaria, Pest, Identification, Solitarious phase, Gregarious phase


Schistocerca gregaria is a notorious pest amongst insects populating around the globe. S. gregaria form swarms that can spread across millions of square kilometers daily, significantly impacting international economies, societies, and ecosystems. The invasions can devastate the rural communities in the affected areas, threatening their ability to provide for themselves and their families with food. Many millions of dollars are often spent on control measures, and the widespread use of chemical insecticides has negative consequences for the ecosystem. During the present study 597 specimen of Schistocerca gregaria collected from different localities of Taluka Dadu. These specimens were identified according to the four different coloration; Pink, Light Brown, Yellow, and White. Solitarious phase specimens 104 and 493 Gregarious phase collected from various localities. Besides this, the distribution, morphology, and diversity of S.gregaria have been presented in this study.
