    Alternative Strategy: Entomopathogenic nematodes are being applied to tree stumps on coniferous clearfell sites in Europe for inundative biological control of the large pine weevil (Hylobius abietis; Coleoptera: Curculionidae), a major forestry pest. We investigated the risk that two nematode species, Steinernema carpocapsae and Heterorhabditis downesi (Nematoda: Rhabditidae), present to longhorn beetle Rhagium bifasciatum (Coleoptera: Cerambycidae), a service-providing, non-target saproxylic insect on clearfell sites. On six clearfell sites sampled one to twelve months after S. carpocapsae had been inundatively applied to tree stumps for suppression of pine weevil, <10% of deadwood logs contained infected R. bifasciatum and <4% of 1989 R. bifasciatum individuals in logs were infected. Infection was recorded a year after nematodes had been applied, however, suggesting that nematodes were recycling within logs in the field. Incidence of R. bifasciatum infection decreased significantly with increasing distance between a log and the nearest treated tree stump. Thus, our results indicate that entomopathogenic nematodes can infect and recycle in R. bifasciatum, but that the risk to this and other saproxylic non-target insects is limited by the targeted application of nematodes to tree stumps.

    Alternative Strategy: Control is based upon the weeds present and the weeds likely to be present, environmental or operational restrictions, soil type and characteristics (fine sand 1st rotation sites tend to blow away with broadcast spraying resulting in top soil erosion and sand blasting of seedlings), topography, site preparation method (spot cultivation, mounding, line marking only), preferred application method (aerial or ground based) and for second year weed control sites the growth already achieved since planting. Under advice from the research section, where practical, expensive and high application rate are used low rate, lower risk and lower cost products can be substituted.

    Alternative Strategy: In New Zealand, significant progress towards a bait-delivered contraceptive vaccine for possums is expected within the near future. The system of delivery still poses some challenges and immigration of fertile animals from non-treated areas may compensate for treatment effects. Population models indicated that fertility control can be effective where population reduction does not have to be as rapid as lethal techniques, or where the objective is to maintain a population at low levels established previously with exclusion or lethal techniques. Fertility control is not likely to be useful for short-term, localized management of browsing damage, e.g. during the establishment phase

    Alternative Strategy: Podisus nigrispinus and Supputius cincticeps are predators of lepidopteran defoliating insects, especially of eucalyptus brown looper Thyrinteina arnobia. Natural enemies can be promoted by reducing weed control (retaining weeds between trees) and preserving natural forests on part of the managed area (appropriate to scale of the plantation). Regulation of lepidopteran defoliators (such as Euselasia apisaon) is enhanced where fragments of natural vegetation are present, e.g. through increased predation parasitoid wasps (Murta el al 2008; Zanuncio et al 2009)
