“…This phenomenon was previously recorded in S. paludicola by Fullaway (1947b), who reported larvae feeding on the nonnative forestry trees Lophostemon and Grevillea during a 1946 outbreak on East Maui. A number of species of lepidopteran larvae, particularly during the later instars, are known to become less selective during population outbreaks (Rossiter 1987, Tuskes et al 1996, Rieske and Townsend 2005. Diurnal activity of adult moths is another unusual behavior we observed in S. paludicola, which is typically nocturnal.…”

The koa moth, Scotorythra paludicola, is an endemic Hawaiian moth that undergoes sporadic outbreaks in koa forests in Hawai'i, causing vast defoliations of its host plant, Acacia koa. We studied one such outbreak that occurred on East Maui in 2003, in which approximately 16 km 2 of forest were defoliated. We collected adult moths and larvae, and recorded size-class distribution of larvae in defoliated regions. Larvae at a given site tended to be of a similar size class, suggesting that outbreaks were synchronous, and mean development time from first instar to adulthood was 42 days under laboratory conditions. Mortality of field-collected, laboratory-reared larvae due to disease was high (80%), making it impossible to quantify meaningful parasitism rates, but three nonnative hymenopteran primary parasitoids were reared (the braconids Meteorus laphygmae and Cotesia marginiventris, and the ichneumonid Hyposoter exiguae). One ichneumonid hyperparasitoid, Gelis sp., was also reared. No native parasitoids were reared. We found no relationship between occurrence of five koa moth outbreaks on East Maui between 1920 and 2006 and annual or monthly precipitation or temperature during that period.

“…By embedding our willow plots in a landscape of corn and soybeans we inferred that numerous eastern tent caterpillars travelled over 100 m to inflict major herbivory on a non-host food source, willow. It is surprising to find caterpillars so far from the nearest tent, especially because in artificial arenas tent caterpillars moved only 12 m in 2 h (Rieske & Townsend, 2005). Long distance travel has been observed for other species with highly injurious caterpillar stages.…”

“…Thus, the association between habitat and host tree defoliation was likely significant to the dispersal of tent caterpillars and subsequent discovery and defoliation of nearby willow bioenergy crops. Such dynamics are likely to occur only during high density, outbreak years when such severe defoliation is expected (Rieske & Townsend, 2005;Barbosa et al, 2009).…”

“…Eastern tent caterpillars have periods of rapid population growth that result in outbreak densities and density-dependent dispersal of late instar caterpillars to alternate food sources after degradation of the host tree (Fitzgerald, 1995;Rieske & Townsend, 2005). On a local scale (1-10 m) insect herbivores are known to spillover from host plants to nearby palatable plant species with consequences for plant performance (Andersen & Louda, 2008).…”

“…However, the associated susceptibility hypothesis posits that spillover effects could occur on a landscape level, especially within an agricultural community (Barbosa et al, 2009). Spillover dynamics for tent caterpillars may occur on a spatial scale greater than 10 meters as the caterpillars are known to travel up to 7 m in 30 min (Rieske & Townsend, 2005). An open question with broad ecological application centers on identifying landscape characteristics and configurations which are conducive to the spillover of tent caterpillars onto willow biomass crops.…”

Spillover of tent caterpillar (Malacosoma americanum) herbivory onto willow bioenergy crops in an agricultural landscape

The circumstances and potential for insects to damage perennial bioenergy crops is not well understood in the United States. In this study, we evaluated the spillover and herbivory of eastern tent caterpillars (Malacosoma americanum) from host trees onto short rotation coppice (SRC) willow bioenergy crops (Salix sp.). Host trees were all in the Rosaceae family and included Prunus americana, Prunus virginiana and Malus sp. Willow showed greater leaf herbivory with increasing proximity to a defoliated host tree, suggesting that tent caterpillars spilled-over to willow after denuding their host. More tent caterpillar herbivory was associated with greater mortality of willow. This study suggests that landscape context and spatial position of host trees is important to the early establishment of a willow bioenergy crop.
