A Survey of the Lepidoptera, Biogeograhy and Ecology of New Caledonia

I spent 4 months in New Caledonia in 1971 with the thing of constructing a quantitative survey of the night-flying macrolepidoptera with light-traps and an review of the Rhopalocera and microlepidoptera. This fieldwork used to be financed by way of a central authority Grant-in-Aid for clinical Investigations adminis­ tered through the Royal Society, and by means of a provide from the Godman Fund.

This strategy is likely to be employed to a greater or lesser degree by virtually all bloodsucking insects, but it is likely to be used more by forest-dwelling species than by those living in more open terrains (Sutcliffe, 1986). Insects almost certainly also engage in active appetitive behaviour. The evidence for this is that non-activating, non-orientating, non-attracting sampling devices, such as suction traps sunk below ground or electric nets, will often catch large numbers of hungry female insects that are impregnated but not ready for egg laying.

This suggests that other kairomones remain to be identified. It is generally accepted that carbon dioxide can be involved in both the activation and orientation of virtually all blood-sucking insects. 1 per cent in dense vegetation at night. 5 per cent carbon dioxide. 3 The effect of varying the emission rate of carbon dioxide on its drawing power for mosquitoes has been measured by various authors under field conditions. The lower edge of the ‘attraction range’ shown in the figure is the furthest trapping point at which an effect of the carbon dioxide was noted.

This is certainly a possibility as many plant-feeding insects possess piercing and sucking mouthparts that would pre-adapt them for haematophagy. This is seen in the moth Calpe eustrigata, which is one of a group of noctuiids that possess an unusually modified, sharp proboscis used in most species for the penetration of fruit rinds. But C. eustrigata uses it to penetrate vertebrate skin for the purposes of bloodfeeding. It is probable that plant-feeding ancestors of modern-day blood feeders would have developed haematophagy only if they were in a position of continual association with the vertebrate host.
