Dicladispa armigera is a species of leaf beetle from Southeast Asia, often known by its common name: the "rice hispa".
[2] Rice hispa eggs laid by the female beetle are usually inserted beneath the epidermis of the underside of leaves.
[3] Finally the adult beetle, known as an imago, emerges and cuts its way out of the larval tunnel and surrounding leaf.
Additionally, D. armigera is present, but not wide-spread in: Bhutan, Cambodia, China, Indonesia, Iran, Korea, Malaysia, Myanmar, Nepal, Pakistan, Philippines, Sri Lanka, Taiwan, Thailand, Vietnam, and Papua New Guinea.
[5] The high reproductive potential and short generation time are significant contributors to the success of this species.
[8] The white muscardine fungus (Beauveria bassiana) has also been tested as a biological control of the rice hispa.
[9] Adult rice hispa die 5–6 days after inoculation, and white mycelial growth was observed over the surface of the insect.
Infected pupae had white mycelial growth over their body, their size is reduced by half and they become totally deformed.
Larvocel, Calpaste, Azacel, Neem oil, Multineem, and dk-bioneem have all been shown to be effective at reducing D. armigera populations by as much as 96%.
