Oemona hirta (F.) is a New Zealand native longicorn beetle, whose larvae bore into the wood of branches and stems of living trees and vines, causing serious damage. To explore effective methods for maintaining laboratory colonies and biology of immature stages of this species we evaluated four laboratory rearing methods with both natural and artificial(More)
Females of many insects mate multiply but why they do so remains controversial. Here we investigated the effects of multiple matings on female reproductive success of a New Zealand seed bug, Nysius huttoni. We found little evidence for females to gain material (nutritional) benefits through multiple matings because the number of matings did not have(More)
Demographic factors such as operational sex ratio (OSR) and local population density (LPD) are temporally and spatially dynamic in the natural environment but the influence of these variables on male mating success and the mechanisms behind it are still poorly understood and highly controversial. Here, we manipulated the OSR and LPD of a seed bug, Nysius(More)
Oemona hirta (F.) is a New Zealand longicorn beetle. Its larvae are known to bore into wood of branches and stems of living trees and vines of over 50 species, most of which are exotic such as citrus, apple, persimmon, cherry, chestnut, almond, walnut, grape and poplar, causing serious damage (Miller, 1925; Hudson, 1934; Dumbleton, 1937; Clearwater, 1981;(More)
