Impact of habitat variation on the species diversity and richness of phytoseiid predatory mites (Acari: Mesostigmata)- A case study from north Kerala


Sheeja UM, Sebastian CD, Ramani N

The present study was undertaken to generate data on the impact of habitat variations viz., open and closed (polyhouse) agro-ecosystems on the relative distribution pattern of predatory mites belonging to the family Phytoseiidae. Plant dwelling species of phytoseiid mites were recovered by collecting samples of aerial parts of economically important crops cultivated / grown in two different localities representing outdoor place condition as well as in polyhouses in the Kozhikode district of Kerala. The mite specimens were segregated from the plant samples through microscopic screening and the collected specimens were preserved, dehydrated and slide mounted in Hoyer’s medium. Slide mounted specimens were oven dried and identified following relevant keys/literature as well as seeking confirmation from experts. Data on the species diversity and abundance of phytoseiid predators revealed the predominance of these mites in open habitats when compared to the polyhouse condition. Maximum number of phytoseiid mites could be collected from the outdoor of Kunnathukara Organic Farmhouse (Site IIo = 647) followed by outdoor of Kurumpoyil Farmhouse (Site Io = 160). The lowest numbers of phytoseiid were collected from the polyhouses. The diversity indices of all the ecosystems showed higher diversity and Kunnathukara Organic Farm showed highest diversity during the survey.
