A Preliminary Survey of Olive Grove in Biskra (Southeast Algeria) Reveals a High Diversity of Thrips and New Records.

This study was conducted to determine Thysanoptera species composition associated with olive trees, fruit injury, fluctuations in the abundance of the most phytophagous species relative to the phenological stages of the olive tree, and the temporal variations in the species in relation to environmental variations in Biskra province between 2018 and 2020. The olive orchard chosen for this study is located at the Experimental Station of the Technical Institute for the Development of Saharan Agriculture (ITDAS) in El Outaya (Biskra, a Saharan region of Algeria). Five trees were sampled each week, and thrips were collected by shaking 20 twigs (4 twigs per tree).

New records of Phlaeothripinae from New Caledonia, with the description of a new species of Adraneothrips Hood (Thysanoptera, Phlaeothripidae).

Four species of phlaeothripines are newly recorded and illustrated from New Caledonia: Adraneothrips moundi n. sp., Baenothrips cf.

Antennal sense cone variation in Teuchothrips species of New Caledonia, with one new generic combination (Thysanoptera, Phlaeothripinae).

Four species of Teuchothrips are recognised as endemic to New Caledonia and distinct from the many species of this genus in Australia. Three of these species are shown to have a variable number of sense cones on antennal segment IV, in contrast to most recorded species in the Liothrips-lineage. One endemic species is removed from Teuchothrips and considered here as Neocecidothrips pacificus (Bianchi) comb.

Pennathrips (Thysanoptera: Thripidae), a new panchaetothripine genus from New Caledonia.

The Pacific island of New Caledonia is located about 1500km East of Australia just north of the Tropic of Capricorn. It has a rich endemic flora involving more than 5000 plant species (Endemia.nc 2021; Guillaumin 1948), but the only account of the Thysanoptera fauna apart from some new species descriptions is a check-list of 44 genera and 68 species (Bournier Mound 2000).

emCopidothrips octarticulatus/em recorded from Tahiti, with first description of the male and larvae (Thysanoptera, Thripidae, Panchaetothripinae).

Heliothrips (Parthenothrips) octarcticulatus was originally described by Schmutz (1913) from Sri Lanka. Subsequently, Hood (1954) described from Taiwan a new genus and species Copidothrips formosus, and then Stannard and Mitri (1962) described a further new genus and species, Mesostenothrips kraussi, from Kiribati and Gibert Islands. Bhatti (1967, 1990), recognized that only a single genus and species was involved amongst these names, established the resultant synonymies, and recorded the species octarcticulatus from various localities between the Seychelles and five different Pacific Island groups.

Dendrothripoides moundi (Thysanoptera, Thripidae), a new species from Madagascar.

The genus Dendrothripoides was originally described by Bagnall (1923) from India and is currently represented by five species (ThripsWiki 2020). Dendrothripoides innoxius (Karny) is widely distributed in the Oriental and Pacific regions; D. microchaetus Okajima is from the Philippines and Indonesian archipelago; D.

A new species of the genus Thrips (Thysanoptera, Thripidae) from the Malagasy Region.

The genus Thrips comprises 296 species (ThripsWiki 2019) and is the largest of all Terebrantian genera. The only other Thysanopteran genera comparable in size are the phlaeothripids Haplothrips and Liothrips. Species of Thrips can be found in flowers and on leaves of a wide variety of plants from grasses to trees.

Composition and Structure of Thripidae Populations in Crops of Three Geographical Regions in Colombia.

The composition and structure of thrips populations were determined in agroecosystems of 10 crops in the Andean, Caribbean, and Orinoquia regions of Colombia. From 18,183 identified specimens, 81 species belonging to 20 genera and three families were found. The Andean region was the most diverse with 60 species (n = 11,360, Chao 1 = 70.

Presence and Distribution of Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) in Colombia.

The presence and distribution of Scirtothrips dorsalis was reported in Colombia in the Andean, Caribbean, and Orinoquia regions, from 0 to 1,200 meters of altitude (MASL) in the warm climate zone, with less than 2,000 mm rainfall per year and a temperature above 24°C, which corresponds to the tropical dry forest life zone (TDF). Larvae and adults of S. dorsalis were found on 13 plant species belonging to 12 genera in 12 families, of 181 plant species sampled from 129 genera in 47 families sampled.

sp.n. from Delaware, North America, with a key to the three species of this genus.

The genus Konothrips was erected by Bhatti (1990) for a single species, tuttlei, that was described from Arizona in the genus Chirothrips by zur Strassen (1967). The new genus was distinguished by the longitudinally orientated sculpture on the abdominal terga and sterna, the fore wing costa with only a single seta, and the ovipositor lacking teeth (Bhatti 1990). Subsequently, Nakahara and Foottit (2012) described in Konothrips a second species, colei, from Texas.

Seasonal Terpene Variation in Needles of Pinus radiata (Pinales: Pinaceae) Trees Attacked by Tomicus piniperda (Coleoptera: Scolytinae) and the Effect of Limonene on Beetle Aggregation.

Concentrations of four monoterpenes were determined in needles of Pinus radiata (D.Don) (Pinales: Pinaceae) trees that were attacked or nonattacked by Tomicus piniperda (L.) (Coleoptera: Scolytinae).

Variation in virulence of Beauveria bassiana and B. pseudobassiana to the pine weevil Pissodes nemorensis in relation to mycelium characteristics and virulence genes.

Entomopathogenic fungi such as Beauveria spp. have potential applications in the biocontrol of insect pests but little is known regarding their infectivity to the pine weevil Pissodes nemorensis. In this study, five isolates of Beauveria pseudobassiana and five isolates of Beauveria bassiana were tested for characteristics correlating with virulence on P.

Replacement names for two homonyms of Karny: one from California, the other for a species damaging crops in Mexico.

There are nearly 280 species of Liothrips listed from around the world (ThripsWiki 2016), all of them presumably feeding and breeding on the leaves of higher plants, and sometimes inducing or being associated with galls (Mound 1994). Despite this, for most of these species the identity of the plant species on which they are dependent is rarely known, and a particularly high proportion of the species are based on few specimens or even single individuals (cf Table 1). As a result, the identity of many of these named species continues to be in doubt.

Comparison of different light sources for trapping Culicoides biting midges, mosquitoes and other dipterans.

The response of Culicoides biting midges, mosquitoes and other dipterans to different wavelengths was evaluated in a farm meadow in northern Spain. A total of 9449 specimens of 23 species of Culicoides, 5495 other ceratopogonids (non-biting midges), 602 culicids and 12428 other mixed dipterans were captured. Centers for Disease Control and Prevention (CDC) suction light traps fitted with five light emitting diodes (LEDs) (white, green, red, blue, ultraviolet) were run for 15 consecutive nights.
