Humidity and host-plant as important factors influencing the pre-imaginal development of fruit lies (Diptera : Tephritidae) : [Poster]

Duyck P.F., David P., Glenac S., Quilici S.. 2006. In : Horticulture, CIRAD highlights. Montpellier : CIRAD-FLHOR, 1 p..

Fruits flies (Diptera : Tephritidae) are serious pests on fruit vegetable crops in most tropical countries. In Réunion Island, four species of Tephritidae cause damages on fruit crops, namely the Mascarenes fruit fly. Ceratitis catoirii (Guérin Méneville), the Mediterranean fruit fly,C. capitata (Wiedmann) , the Natal fruit fly, C.rosa karsh, and the recently invasive peach fruit fly, Bactrocera zonata (Saunders). If temperature has strong influence on the survivorship during the pré-impaginal development of these four species (Duyck and Quilici 2002 ; Duyck et al. 2004), the influence of humidity and host fruit has received little attention up to now.
