Abstract
This study examines seasonal assemblage of
grasshopper fauna across three tropical dry deciduous forests in Sambalpur
district, Odisha. Grasshoppers were sampling was conducted from November 2022
to October 2023 using sweep nets, visual transect surveys, and pitfall traps in
three different tropical dry deciduous forest habitat. During this study a
total of 35 grasshopper species were recorded that belongs to 26 genera and
four families i.e. Gryllidae, Acrididae, Pyrgomorphidae, and Tettigoniidae were
recorded. Acrididae were recorded as the most dominant family then others. Higher
species richness and individual was recorded in undisturbed reserved forests,
followed by reserve-planted and disturbed forests. The most abundant species
included Acridaexaltata, Acridagigantea, Attactomorpha crenulata,
Diabolocatantopsaxillaris, Diabolocatantopspinguis, Oxyafusco vittata, Oxya
hyla, Spathosternum prasiniferum, and Teleogryllustestaceus.
Diversity indices, such as species richness and abundance varied significantly
across three forest habitats, reflecting the influence of environmental conditions
and vegetation structure on Grasshopper assemblages. Seasonal variations
significantly influenced diversity pertain across the tropical dry deciduous
forest habitat of the study areas in which highest species richness observed
during the rainy season in reserve-planted forests and the lowest during summer
in disturbed forests. Grasshopper abundance in reserve-planted forests during
the rainy season underscores their adaptability to tropical dry forest
habitats, which is largely influenced by vegetation cover. This study
highlights the ecological significance of tropical dry deciduous forests as
critical habitats for Grasshoppers. Continuous, large-scale research is
essential to understand their ecological roles, distribution, and microhabitat
preferences, contributing to biodiversity in these tropical dry deciduous
forests ecosystem.
