Survey of thrips on eut flowers and neighbour plants and biology of Frankliniella panamensis Hood (Thysanoptera: Thripidae)

Abstract

A thrips populations survey on commercial cut flower crops and wild plants around the greenhouse was carried out in the locality of La Ceja, department of Antioquia. The fo­llowing thrips species were found: Frankli­niella panamensis Hood, Thrips australis Bagnall, Taeniothrips frici (Uzel), and Neohydotothrips near burungae (Hood) on­chrysanthemum (Dendrantema grandiflora) and the species F. occidentalis (Pergande) on bouvardia (Beauvardia longiflorum). The species Haplothrips godwegi Franklin, Mi­crocephalothrips abdominalis (D.L. Crawford), Psectrothrips interruptus, Fran­kliniella insularis (Franklin) and Frankli­niella sp. on the following host plants: Tabe­buia rosea flowers, Gazania sp.,Hemeroca­luiz pava, Hypochoeris radicata, Trifolium repens, Physalis peruviana, Oxalis latifolia H.B.K., Cobaea scandens, Lantana morit­ziana, and Eucalyptus sp. The life cycle of F. panamensis was studied under laboratory conditions (T=24.8°C; R.H.=77.9%). The eggs, first instar larva, second instar larva, prepupa, and pupa lasted 2.5, 2.5, 5, 2.5, and 3 days, respectively. The average longevity of the adults was 47 days for the males and 61 for the females. Parthenogenic females laid an average of 17.79 fertile eggs/week and those which reproduce sexually 13.26 fertile eggs/week during their lifetime.
