Abstract:Heliothrips similis sp.n. is described as a close relative of the greenhouse thrips, Heliothrips haemorrhoidalis. This is the third species recognized here in the Neotropical genus Heliothrips. A pest species described from South Africa as Heliothrips sylvanus is transferred to a new genus, Neoheliothrips gen.n., as Neoheliothrips sylvanus (Faure) comb.n.
“…Adult greenhouse thrips were identified morphologically (with pale forewings, body dark brown to black with reticulate head and pronotum, and femora pale-yellow) and habit of feeding on mature leaves (Mound & Walker 1982;Nakahara et al 2015). Immature stages were identified based on their association with adult greenhouse thrips, and supporting traits that differentiate them from other species of the same subfamily Panchaetothripinae in New Zealand.…”
The greenhouse thrips, Heliothrips haemorrhoidalis is a quarantine pest of kiwifruit. There is a need for reliable information on its phenology in kiwifruit orchards to inform the development of new management options. Numbers of larval, pupal and adult greenhouse thrips were counted on leaves of the two main kiwifruit cultivars Actinidia chinensis var. deliciosa (‘Hayward’) at two sites at different times and A. chinensis var. chinensis ‘Zesy002’ at one site. Greenhouse thrips were also counted on leaves of shelter tree species Cryptomeria japonica, and other plants present on kiwifruit orchards, blackberry (Rubus fruticosus s.l.), barberry (Berberis glaucocarpa), and wineberry (Aristotelia serrata) across a number of sites at different times. There was a strong seasonal pattern to the phenology of greenhouse thrips and it was relatively synchronous for all the host plants surveyed. In general, number of greenhouse thrips on foliage increased from January to peak in April or May before declining in late autumn or winter and remaining low until the following January or February. The phenology of greenhouse thrips followed the same seasonal pattern for a variety of host plants found on kiwifruit orchards at sites in the Bay of Plenty across two two-year time periods. Therefore, host species does not appear to be a factor affecting the phenology of thrips. Other, non-host factors such as microclimate may be important drivers of phenology but they require further study. The consistency of the seasonal pattern of relative abundance means that there is a well-defined window to target for thrips management.

“…Forty-nine adult insects were collected and preserved in AGA solution (1:1:10 parts of glycerin, glacial acetic acid, and ethyl alcohol 60%, respectively). Specimens were slide-mounted (Mound & Kibby 1998) and identified as the greenhouse thrips, Heliothrips haemorrhoidalis (Bouché) (Thysanoptera: Thripidae), based on specialized taxonomic keys (Mound & Marulo 1998;Nakahara et al 2015).…”

“…Three species are now considered valid in this genus, all from South America (Nakahara et al 2015). Two of the species have restricted distributions in southern Brazil, but the third is found worldwide.…”
An illustrated identification system is presented to 99 species and 49 genera in three families recorded from the Hawaiian Islands in the Thysanoptera suborder Terebrantia. Only seven (possibly eight) of these species are considered endemic, the remainder being adventive to these islands. The only previous study of Hawaiian Thysanoptera, by Zimmerman in 1948, included 47 Terebrantia species in 21 genera.
