    • Abstract


      The population trends of the planthoppers,Dichoptera hyalinata Fabricius (Dictyopharidae),Eurybrachys tomentosa Fabricius (Eurybrachidae), andRicania fenestrata Fabricius (Ricaniidae) were studied with reference to the abiotic factors like temperature, humidity and rainfall and biotic factors like two nymphal ectoparasites,Dryinus sp. (A)* andDryinus sp. (B)* (Dryinidae: Hymenoptera) and two egg parasites,Proleurocerus fulgoridis Ferriere (Encyrtidae: Hymenoptera) andTetrastichus sp. (Eulophidae: Hymenoptera).
