Abstract

Six species of scelionid egg-parasites of several species of pentatomids including the major coffee pestsAntestiopsis spp. were used for rearing experiments in eggs of species other than their normal host. One species,Gryon antestiae (Dodd), laid in eggs of 4 genera of pentatomids and bred satisfactorily in eggs of 3 of them.

Although the normal host of this parasite isAntestiöpsis experiments showed thatAgonoscelis versicolor (F.) is also a very satisfactory host, but though these pentatomids are sympatric the parasite has never been recorded fromAgonoscelis in the field.

Experiments withTelenomus seychellensis Kieffer andGryon antestiae showed that they could breed satisfactorily in unfertilized eggs ofAntestiopsis and as these eggs remain in good condition long after fertilized eggs have hatched this must be a factor contributing to the maintenance of parasite populations in the field.

Résumé

Six espèces de scelionides parasites d’œufs de plusieurs espèces de pentatomides comprenant le ravageur principal du café,Antestiopsis spp. ont été utilisées au cours d’essais d’élevage dans des œufs d’espèces autres que leurs hôtes normaux. Une espèce,Gryon antestiae (Dodd) a pondu dans les œufs de 4 genres de pentatomides et s’est développé dans les œufs de 3 de ceux-ci. Bien que l’hôte normal de ce parasite soitAntestiopsis les essais montrent queAgonoscelis versicolor (F.) est également un hôte très convenable, toutefois même si ces pentatomides sont sympatriques le parasite n’a jamais été obtenu deAgonoscelis dans la nature.

Les essais avecTelenomus seychellensis Kieffer etGryon antestiae indiquent qu’ils peuvent être elevés dans des œufs non fécondés deAntestiopsis. Du fait que ces œufs se conservent en bon état longtemps après l’éclosion des œufs fécondés cela peut être un facteur contribuant au maintien des populations du parasite dans la nature.
