Data were collected on Mantispa sayi Banks regarding larval parasitism of spiders, parasitism ratios, within-host distribution, longevity of nonparasitizing larvae, and long-term use of a communal ...oviposition site in southern Texas. Most egg clusters were laid on the underside of wooden eaves, which usually had a high density and diversity of web-building and hunting spiders. One site was repeatedly used during 6 yr of observation and on one date contained 403 egg clusters. Larvae hatched in 9-10 d at 26.5 degree C but died within 96 h if they did not locate and attach to a suitable host. First instars, which are facultative ectoparasites, were collected from 13 species of spiders representing six families (Araneidae, Gnaphosidae, Mimetidae, Salticidae, Scytodidae, and Tetragnathidae).
Conservationists are striving to manage wild Patagonia guancos in Chile for sustained-yield production of meat and wool products, which would economically benefit local ranchers. Although the ...guanacos' population has increased, there are still many challenges that lie ahead.
