The predatory mite Typhlodromalus aripo feeds on cassava plants, enhancing its survival during prey scarcity. This plant-feeding behavior aids its effectiveness in controlling the cassava green mite (CGM).

Area of Science:

  • Ecology
  • Entomology
  • Biological Control

Background:

  • Arthropod predator feeding on host plants can influence tritrophic interactions.
  • Typhlodromalus aripo is a key biological control agent for Monoychellus tanajoa (cassava green mite, CGM) on cassava.
  • Understanding predator feeding habits is crucial for optimizing biological control strategies.

Purpose of the Study:

  • To investigate whether the predatory mite Typhlodromalus aripo feeds on its host plant, cassava.
  • To compare the survival rates of T. aripo and another predatory mite, Neoseiulus idaeus, on cassava leaf discs.
  • To assess the role of plant feeding in the persistence and efficacy of T. aripo for CGM control.

Main Methods:

  • Development of a novel technique to detect plant feeding using a systemic insecticide.

Related Experiment Videos

  • Application of the technique to confirm plant material consumption by T. aripo.
  • Comparative survival assays of T. aripo and N. idaeus on cassava leaf discs under conditions of prey scarcity.

    • Main Results:

    • Typhlodromalus aripo was confirmed to feed on plant-borne material.
    • Other predatory mite species, Neoseiulus idaeus and Phytoseiulus persimilis, did not exhibit plant feeding.
    • T. aripo showed significantly higher survival rates on cassava leaf discs compared to N. idaeus, indicating better tolerance to prey scarcity.

    Conclusions:

    • Plant feeding by T. aripo is a significant factor enabling its survival during periods of low prey availability.
    • This supplementary feeding strategy likely contributes to the persistence of T. aripo populations in cassava fields.
    • The ability to feed on plants enhances the efficacy of T. aripo as a biological control agent against the cassava green mite (CGM).
