- Abstract
A study was conducted to know the interaction between ants, other insect visitors and extrafioral nectaries (EFNs) in selected crops at experimental farms of Faculty of agriculture, Annamalai University in which field incidence of ants, herbivores and predators in five EFN-bearing crops viz., Vigna mungo, Vigna radiata, Gossypium hirsutum, Dolichos lablab var. typicus and Ricinus communis were observed. Among the herbivores Phenacoccus sp., Aphis sp. and Helicoverpa sp. were highest and among predators Coccinellidae and Vespidae was highest. Camponotus compressus was highest in Vigna mungo, Vigna radiata and Gossypium hirsutum. In Hibiscus cannabinus, Ricinus communis and Dolichos lablab var. typicus, Myrmicaria brunnea and Solenopsis geminata was highest respectively. In ant - exclusion experiment, in both control and treatment Phenacoccus solenopsis showed gradually decreasing pattern from the first week to fourth week. But Coccinellidae and Mantidae showed increasing and fluctuating pattern during every consecutive week in control and treatment respectively. Parasitized mealybug mummies number (by the parasitoid, Aenasius arizonensis Hayat) showed decreasing and increasing pattern from first to fourth week in control and treatment respectively.
