Life cycle and host specificity of Eutinobothrus sp. (Col.: Curculionidae) an agent for biological control of Sida acuta (Malvaceae) in the Northern Territory, Australia
Entomophaga 40 (3-4), 345-355
Abstract: The biology of an undescribed weevil, Eutinobothrus sp., and its specificity to Sida acuta, a serious weed in northern Australia, were studied in a quarantine facility in Australia. Sixty-eight plant species were screened and only S. acuta and S. rhombifolia could sustain populations of Eutinobothrus sp. Adults feed externally on the stems and oviposit in feeding scars. Larvae feed internally and pupate in the stem. Prepupae and pupae may aestivate in the stem and adults emerge with the onset of the wet season when new growth is evident. Eutinobothrus sp. was released in January, 1994 in the Northern Territory and has established.
