A new species of the Frankliniella cephalica group, from Central Costa Rica, is described under the name "Frankliniella morerai n.sp.". It is closely related to Frankliniella sandovalensis. Both species have translucent bodies, but the new species can be distinguished by these characteristics: setae io II in position 1/2, a complete comb on abdominal segment VIII, antennal segments without coloration and setae po IV longer. It was found in low density in crops of chilli, tomato, lettuce, sweet potato and coriander. A comparative table with other species of this group is included to facilitate diagnosis.  相似文献

The foraging behaviors of predatory female Franklinothrips orizabensis Johansen towards Scirtothrips perseae Nakahara and Heliothrips haemorrhoidalis (Bouché) in avocado leaf arenas were videotaped and analyzed. F. orizabensis encountered and attacked more second instar S. perseae with 80% (n=113) attacks on this life stage being observed compared to 20% on first instars (n=28) when equal numbers of these prey were presented simultaneously. However, there was no significance difference by life stage for the probability of being attacked after being encountered. Successful attacks by F. orizabensis only occurred against propupal H. haemorrhoidalis (n=6) that lacked protective fecal droplets, 65% of prey encounters were with this life stage, and 6% of encounters with propupae resulted in attacks. Second instar H. haemorrhoidalis larvae bearing protective droplets were encountered less frequently and were not attacked when contacted even though equal numbers of both stages were presented simultaneously. Consequently, the mean proportion of the time spent grooming by F. orizanbensis females attacking immature H. haemorrhoidalis was four times greater than that for females attacking S. perseae larvae even though there was no significant difference in mean time (s) spent in each grooming bout. Significant differences in mean consumption times by F. orizabensis existed across life stages and prey species. Consumption times were shortest for first instar S. perseae larvae, intermediate for second instars, and longest for H. haemorrhoidalis propupae. Mean consumption times for sequentially attacked second instar S. perseae declined significantly indicating satiation of predators. Predators would spend on average approximately 7–13 s probing leaves with mouthparts and feeding on fluids; a behavior that on average occupied 2–5% of their time. This result may explain observed mortality of F. orizabensis in the laboratory and field when this predator forages on avocado leaves that have been treated with insecticides that exhibit translaminar activity.  相似文献

Abstract

Three new species of genus Thrips are described—austellus, coprosmae, and phormiicola—which are closely related to the common New Zealand species T. obscuratus (Crawford). The systematic and zoogeographic significance of this endemic species-group is discussed. Physemothrips hadrus n.sp. is described from the South Island; the only other member of this genus is from Macquarie Island. Anaphothrips zelandicus n.sp. is described from the South Island and the Chatham and Antipodes islands, A. woodi Pitkin is recorded from New Zealand, and the relationships of these two species to the Australian fauna are discussed.  相似文献
