An illustrated key is provided for the identification of 39 genera of Thysanoptera--Phlaeothripinae with species that live in association with dead branches and leaf-litter in Australia and are considered to be fungus-feeding. Seven of these genera are not previously recorded from this continent, including un-named species of Deplorothrips, Malacothrips, Mystrothrips, Preeriella and Tylothrips,...

Thrips are minute insects and belong to the family thripidae of the order Thysanoptera. Thrips are less than two millimeters long, slender like and agile insects. Head of Scirtothrips dorsalis is pale in colour longer than broad, 217.5-237 μm long and 175-194 μm wide across the eyes. Eyes are redish in colour, 75-89 μm long and 63-70 μm wide at the middle and three occili are arranged triangula...

The foraging behaviors of predatory female Franklinothrips orizabensis Johansen towards Scirtothrips perseae Nakahara and Heliothrips haemorrhoidalis (Bouch e) in avocado leaf arenas were videotaped and analyzed. F. orizabensis encountered and attacked more second instar S. perseae with 80% ðn 1⁄4 113Þ attacks on this life stage being observed compared to 20% on first instars ðn 1⁄4 28Þ when eq...

Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), is a well-known onion pest worldwide. Onion thrips cause both direct and indirect damage to onion by feeding and ovipositing on leaves that may cause green onions (scallions) to be unmarketable and dry bulb onion size to be reduced. Onion thrips can also transmit several plant pathogens that reduce onion bulb size and quality. One ...

Widespread and common across much of the drier areas of western Africa, the woody shrub Guiera senegalensis (Combretaceae) is the sole member of its genus. Similarly widespread is Vuilletia houardi, a thrips species that induces galls on this shrub, and is recorded from Mali, Senegal, Gambia and northern Nigeria (Pitkin & Mound 1973). Moreover, large numbers of galls, together with their includ...

Guerothrips moundi gen. et sp. n., (Thripidae, Thripinae) is described from flowers of the herbaceus plant Waltheria indica (Sterculiaceae) found in Tapachula, Chiapas, Mexico. G. moundi is a member of the Frankliniella genus-group, but is distinguished by the presence of sternal discal setae on the abdomen. The available specimens are all brachypterous.

Scolothrips ochoa sp. n. is described from Australia feeding on mites of the genus Raoiella (Tenuipalpidae). Apparently host-specific, this thrips is unusual within the Thripinae in lacking ocellar setae pairs I and II. Moreover, it differs from other Scolothrips species in lacking elongate pronotal midlateral setae, and by having antennal segments III–IV and V– VI broadly joined.

The aquatic grass-inhabiting thrip, Frankliniella zizaniophila (Han & Zhang 1982) (Thripidae: Thripinae), is redescribed and illustrated, and the larvae and the yellow color type of this species are described for the first time. Judging from its unique morphological characters and host plant, the systematic position of this species in Frankliniella is questionable, but until the thrips fauna of...

Aeolothrips gundeliae sp. n. is described, and two bicolored species of the same genus, Aeolothrips ericae Bagnall and Aeolothrips albithorax Pelikan are newly reported from northeast of Iran. Diagnostic characters are provided for each species as well as illustrations to distinguish these species.

An illustrated key is provided to distinguish the 34 species of genus Thrips reported from the Afrotropical Region, including La Réunion. Seven new synonyms are established as a result of checking type specimens; two new species are described, T. solari from Nigeria and T. kurahashii from South Africa; and the new combination Craspedothrips ghesquierei (Priesner) is established for a species de...
