The Australian pasture pest Adoryphorus couloni (redheaded cockchafer RHCC) continues to slowly spread from the Port Hills and Banks Peninsula through Christchurch towards productive agricultural land on the Canterbury Plains There are currently no products chemical or biological registered in New Zealand to control this pest In Christchurch several parks used extensively for human recreation were badly damaged by RHCC grubs in the autumn/early winter of 2008 and had to be treated with chemical insecticides (diazinon) Laboratory trials were thus carried out to assess the susceptibility of New Zealand populations of RHCC to a microbial biocontrol agent Metarhizium anisopliae DATF001 (ChaferGuard) registered in Australia Fungal activity was directly influenced by temperature and mode of application Infection and mortality occurred faster at 20C than 15C High mortality levels (90100 after 7 weeks) were obtained when larvae were treated by topical application (105 conidia/grub) or exposure to the dry ChaferGuard formulation in soil; >80 of the cadavers in these treatments were mycosed Direct incorporation of conidia into soil was the least effective treatment Grass grub (Costelytra zealandica) was unaffected by the fungus This trial confirmed the efficacy of DATF001 and its potential for use against New Zealand populations of RHCC

Direct Drilling

Microbial control agents targeting soildwelling organisms need to be compatible with commonly used fertilisers The bacterium Serratia entomophila is used as a microbial control agent for control of the New Zealand grass grub Costelytra zealandica and Beauveria bassiana is an entomopathogenic fungus used to control a range of insect pests These biocontrol agents were formulated into granules and applied to pots together with five fertilisers commonly used on pastures throughout New Zealand Compatibility with S entomophila was also assessed in a field trial where treatments were applied by direct drilling and surface application There appeared to be no deleterious effect from the application of the fertiliser treatments on the establishment and survival of either S entomophila or B bassiana On the contrary there was a suggestion that some nitrogenous fertilisers may lead to an increase in numbers of the bacterial biocontrol agent

Male Beetle

Phenol the attractant pheromone of adult males of the native New Zealand grass grub Costelytra zealandica (White) is produced in the beetles as the result of bacterial degradation of tyrosine A lure consisting of a resin impregnated with phenol has been widely used to monitor male beetle flight activity The present formulation is highly attractive for the first week in the field but then loses activity rapidly A number of phenolcontaining formulations were tested to improve the lure A new formulation gave lower catches that were more stable with time producing data more suitable for population density estimation Phenylacetaldehyde a bacterial metabolite of phenylalanine was tested as a possible synergist to phenol Field results showed that this floral compound exhibited no behaviourallyactive properties to grass grubs when tested together with phenol Catches with water traps were compared with those in sticky delta and flat delta traps in two vineyards and in pasture Water traps caught four times more beetles

Of four diets tested, one based on lima beans and casein was selected as the best and easiest for rearing third instars of Japanse beetles, Popillia japonica Newman. The diet gave the best survival and heaviest pupae and was previously used for rearing larvae of the New Zealand grass grub, Costelytra zealandica (White).
