“…Some grasses, particularly tall fescue, are tolerant to grass grub feeding (Kain et al 1979) possibly as a consequence of its rooting structure and biomass (Prestidge et al 1985) but McCallum et al (1990) found tall fescue and cocksfoot to be resistant. A plant that is tolerant of grass grub can support higher larval numbers than, for example, ryegrass without being unduly damaged whereas a resistant plant is an unsuitable host.…”

Two exotic pests, Argentine stem weevil (ASW) and clover root weevil (CRW) are causing damage estimated at up to $200 M p.a. and $235 M p.a. respectively in dairy and sheep and beef pastures. While CRW is subject to successful biological control management it still causes considerable losses. Lesser pests also contribute to lost production, particularly as they often coexist with more major pests. However, their economic cost to New Zealand is difficult to calculate due to the variable nature of infestations on both temporal and spatial scales. At farm and paddock level, it is abundantly clear that substantial savings could be made if pest management is achieved. It is equally clear that in many instances the tools to do so are limited but if developed would contribute substantially to farm profitability.

“…Root herbivoury by the larvae of these coleopteran species can influence the productivity of pasture systems by causing reductions in overall plant dry matter production, significant changes in pasture composition and decreases in the nutritional value of pasture (e.g. Kain et al 1979;King et al 1982;Gerard 2002). With the exception of H. arator, adults are not considered to be economically damaging in established pasture.…”

“…In pasture both the adults and larvae of H. arator feed on graminaceous species (King et al 1982) while S. lepidus feeding is confined to plants in the genus Trifolium with a strong preference shown for white clover (Clements & Murray 1991). Feeding by C. zealandica occurs on both grasses and clovers with a preference for the latter being exhibited (Kain et al 1979). Naupactus leucoloma larvae feed on a range of plant species.…”

In autumn 1998 a farm scale replicated field trial was established in Waikato, New Zealand, to measure the productivity of combinations of old and new ryegrass and white clover cultivars. Colonisation in the first two years of the trial by Costelytra zealandica, Heteronychus arator, Naupactus leucoloma and Sitona lepidus was monitored. By the end of winter 2000, no difference in densities of any of the pest species monitored could be attributed to cultivar treatments. However, dispersal behaviour and soil type did have a significant effect on pest densities. Naupactus leucoloma, which disperses by walking, was found in greatest densities on the edges of the trial. Costelytra zealandica, which disperses by flying, was initially aggregated in paddocks with shelterbelts. Heavy infestations of H. arator, which also disperses by flying, were associated with good soil drainage. Sitona lepidus, which disperses by flying, was evenly distributed across the trial.

“…The more productive pastures of New Zealand, based on ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.), are susceptible to grass grub (Costelytra zealandica (White» attack (Kain et al 1979). With the withdrawal of DDT insecticide in 1970, a cheap and efficient means of controlling grass grub was lost (Kain & Atkinson 1970).…”

Effect of defoliation frequency on simulated swards of ryegrass, tall fescue, and a 50/50 mixture of the 2 species

Simulated swards of ryegrass, tall fescue, and a SO/50 mixture of the 2 species were established in pots, placed in a controlled-environment room, and harvested at intervals of lO'h, 21, 42, and 63 days. Dry matter production increased with less frequent defoliation but tiller numbers were highest under the 1O lh-day defoliation interval. Digestibility tended to decline at defoliation intervals longer than 21 days. In the mixed sward, tall fescue was more competitive under a 63-day defoliation interval and less competitive under a 2l-day defoliation interval. These results highlight the importance of assessing competition between pasture species in a mixed sward under more than one defoliation regime.
