“…The reproductive capacity of individual females over their entire life span remains unknown, though there have been several studies reporting egg lay in the laboratory and field. Collections of M. privata egg batches laid on Eucalyptus species in the field have found up to 411 eggs per batch (Steinbauer, 2005), with Östrand et al. (2007) reporting that average batch size ranged from 25 to 59 eggs.…”

The frequency of mating in insects is often an important determinant of female reproductive output and male sperm competition. In Lepidoptera that provide male nutrients to the female when mating, it is hypothesized that polyandry may be more prevalent. This is thought to be especially so among species described as income breeders; that is, in species who do not derive all their nutrients for reproductive output entirely from the resources obtained during the larval stage. We selected the geometrid moth, Mnesampela privata (Guenée) (Lepidoptera: Geometridae), to examine this hypothesis further. We found this species was best characterized as an income breeder with female weight on emergence positively correlated with total egg load but not with the number of eggs laid. Further, in accord with income breeders, females emerged with a partially developed egg load and lifetime fecundity was positively correlated with the number of oviposition days. However, in the laboratory we found that incidence of repeated matings or polyandry was rare. When moths were paired singly over their lifetime, only 4% of mated females multiple mated. When females were paired with three males concurrently, female mating success increased from 60 to 81% with multiple mating among mated females increasing to just 15%. Dissection of wild caught M. privata found that polyandry levels were also low with a maximum of 16.4% of females collected at any one time being multiple mated. In accord with theory, mating significantly increased the longevity of females, but not of males, suggesting that females acquire essential resources from male ejaculates. Despite this, multiple mated females showed a trend toward decreasing rather than increasing female reproductive output. Spermatophore size, measured on death of the female, was not correlated with male or female forewing length but was negatively correlated with the number of fertile eggs laid and female longevity. Smaller spermatophore width may be related to uptake of more nutrients by the female from a spermatophore. We discuss our findings in relation to income breeding and its relationship to polyandry in Lepidoptera.

“…Egg parasitoids are especially effective in this regard. For example, species of Telenomus egg parasitoid have been reported to kill between 5% and 69% of M. privata eggs per clutch (109,117) and a Neopolycystus species kills an average of 30% of Paropis atomoria eggs per clutch (45). Egg parasitoids have the advantage of locating herbivores before they disperse and before the larvae are able to defend themselves or hide in leaf shelters.…”

Eucalyptus species, native to Australia, Indonesia, the Philippines, and New Guinea, are the most widely planted hardwood timber species in the world. The trees, moved around the globe as seeds, escaped the diverse community of herbivores found in their native range. However, a number of herbivore species from the native range of eucalypts have invaded many Eucalyptus-growing regions in North America, Europe, Africa, Asia, and South America in the last 30 years. In addition, there have been shifts of native species, particularly in Africa, Asia, and South America, onto Eucalyptus. There are risks that these species as well as generalist herbivores from other parts of the world will invade Australia and threaten the trees in their native range. The risk to Eucalyptus plantations in Australia is further compounded by planting commercially important species outside their endemic range and shifting of local herbivore populations onto new host trees. Understanding the mechanisms underlying host specificity of Australian insects can provide insight into patterns of host range expansion of both native and exotic insects.

“…Other more recent examples include the determination in New Zealand of the sex pheromone of the gum leaf skeletoniser Uraba lugens, an invasive eucalypt lepidopteran herbivore (Gibb et al 2008), and of its subsequent use in predicting the moth's potential distribution and deployment as a monitoring tool as part of an incursion management programme (Kriticos et al 2007;Suckling et al 2005). In Australia, the sex pheromone of the Autumn gum moth, Mnesampela privata, has also been determined (Steinbauer et al 2004;Walker et al 2007) and shows potential as an effective population monitoring tool to be used in eucalypt plantation IPM in southern Australia (Östrand et al 2007;Walker et al 2007).…”
