Foraging herbivores face twin threats of predation and parasite infection, but the risk of predation has received much more attention. We evaluated, experimentally, the role of olfactory cues in predator and parasite risk assessment on the foraging behaviour of a population of marked, free-ranging, red-necked wallabies ( Macropus rufogriseus ). The wallabies adjusted their behaviour according to these olfactory cues. They foraged less, were more vigilant and spent less time at feeders placed in the vicinity of faeces from dogs that had consumed wallaby or kangaroo meat compared with that of dogs feeding on sheep, rabbit or possum meat. Wallabies also showed a species-specific faecal aversion by consuming less food from feeders contaminated with wallaby faeces compared with sympatric kangaroo faeces, whose gastrointestinal parasite fauna differs from that of the wallabies. Combining both parasite and predation cues in a single field experiment revealed that these risks had an additive effect, rather than the wallabies compromising their response to one risk at the expense of the other.

A Better Border Biosecurity (B3)-funded project investigating the interactions between the self-introduced generalist hymenopteran parasitoid Meteorus pulchricornis and native parasitoids of lepidopteran larvae throughout Auckland involved three years of eld work. The last eld trip was to Te Hauturu-o-Toi (Little Barrier Island) in December 2016 to survey some of the least-modi ed native forest in the North Island. Forty Cleora scriptaria moth larvae were collected by hand from Piper excelsum (kawakawa) host plants into ziplock bags, with a small amount of leaf material to support feeding. They were transported to the laboratory and reared to fate in a temperature-controlled room. Of the 40 larvae collected, twelve were parasitised by M. pulchricornis. This is the rst record of M. pulchricornis from Te Hauturu-o-Toi. In addition, nine larvae were parasitised by an undescribed parasitoid (Casinaria sp. 3). This new species may be endemic only to Te Hauturu-o-Toi, but it may have been out-competed on the more modi ed habitat of mainland Auckland, and found refuge in a more pristine environment. Further surveys of island and mainland parasitoid complexes would provide better baseline risk-assessment data prior to border invasions or importing biocontrol agents.
