ECOLOGY OF BLACK BEETLE HETERONYCHUS ARATOR, INFLUENCE OF PLANT SPECIES ON LARVAL CONSUMPTION, UTILIZATION AND GROWTH

Abstract: The consumption, utilization and growth of third‐instar larvae of black beetle, Heteronychus arator (F.) feeding on roots of ryegrass (Lolium perenne), paspalum (Paspalum ***dilatatum) and white clover (Trifolium repens) were studied. Consumption was greater on the grasses than on white clover when assessed by gravimetric methods, Larvae had a higher growth rate on the grasses. Utilization of the roots of the three species was similar indicating that poor growth on white clover is the result of low consumption… Show more

“…Similarly, growth of H. arator larvae was found to be greater on rye grass (Lolium perenne) and paspalum (Paspalum dilatatum) than on white clover (Trifolium repens). The reduced growth of H. arator on white clover was attributed to low consumption, probably thanks to the presence of feeding deterrents in the roots (King et al 1981). …”

“…In New Zealand H. arator is univoltine, adults emerge in late summer-early autumn (February-March), females develop their ovaries slowly during winter and then oviposit in spring (September-November) (Mercer & King, 1976). The larvae are generalist feeders on soil organic matter and plant roots (King, 1977) and roots of grasses, where the adults tend to aggregate and oviposit (King et al, 1981f), are a more favourable food source than those of legumes such as clovers (King et al, 1981d). While the eggs are tolerant of high soil moisture, the first of the three larval instars, which occur from November-January, is not (King et al, 1981b).…”

“…Feeding, growth, and survival 'Of Mack beetle larvae have, however, been shown to be favoured by grass speoies in comparison with legumes (Kil'\g 1976, 1977, King et al 1975. Oviposition by the adult female black beetle under grass species ensures that larval development takes place in the most favourable environment in terms of diet.…”
