Thrips species biodiversity and dynamic populations in an organic Citrus orchard in northeastern Tunisia

Thrips species diversity in a Citrus organic orchard the region of Mograne Northeastern Tunisia based on biodiversity parameters (Shannon index, dominance, and equitability) showed existence ten thrips species. Among those species, five are phytophagous: tabaci, angusticeps, Frankliniella occidentalis, Limothrips denticornis, Melanthrips fuscus. The remaining predatory: Aeolothrips tenuicornis, fasciatus, intermedius, Franklinothrips meaglops, one genus, Haplothrips sp. most abundant intermedius (55%) followed by angusticeps cottei (the same percentage 11%), F. occidentalis T.tabaci (5% 6%, respectively), fasciatus denticornis (3% 4%) then tennuicornis fuscus 2%). megalops is less (1%). evolution different revealed that emergence reached high levels March April. Biodiversity indexes case lower dominance higher equitability.
