FIG-INSECTS

Wind-borne insects mediate directional pollen transfer between desert fig trees 160 kilometers apart.

The question of how far pollen can move between plants has implications for topics as diverse as habitat fragmentation, conservation management, and the containment of genetically modified crops. The monoecious African fig tree Ficus sycomorus L. relies on the small, short-lived, night-flying, host-specific fig wasp Ceratosolen arabicus Mayr for pollination. We used microsatellite markers to ch...

Seasonal occurrence of postharvest dried fruit insects and their parasitoids in a culled fig warehouse.

Parasitoids of dried-fruit insects were surveyed at a culled fig warehouse in Fresno, CA. Three parasitoids of pyralid larvae were found: Habrobracon hebetor (Say), Venturia canescens (Gravenhorst), and at least one species in the genus Goniozus Förster. Two parasitoids of pyralid pupae also were noted: Mesostenus gracilis (Cresson) and a new species of Psilochalcis Keifer. The latter is a new ...

Figs and fig wasps

The current project builds on previous grants under the Darwin Initiative that focused on Nepal's flora, a key one of which dealt with plant information and technology transfer, run by the Natural History Museum in London. But the current project is much more ambitious. Although only funded for three years at present, the team hopes funds will be made available for the estimated 15 years it wil...

Problems Identifying Fig Varieties

Figs are one of the oldest known crops. The identification of different varieties is clouded and confused because of this long history. Efforts were made at various times to describe an accurate system for identifying varieties, with limited success.
