Thysanoptera survey on Vicia faba (broad bean) in the arid Biskra region of Algeria

Abstract

A survey of thrips on broad bean plants was conducted during 2010-2011 in three sites of Biskra, whitch is an arid province in Algeria. Scouting for thrips was carried out on plants and flowers of three fields from three locations: Sidi-Okba, M`ziraa and El-Outaya. Seven thrips species belonging to six genera were recorded. Melanthrips fuscus, Aeolothrips intermedius, Rhipidothrips gratiosus, Frankiliniella occidentalis, thrips physapus, Thrips angusticeps and Odontothrips loti. The two last species were the most abundant in the three locations. Aeolothrips intermedius was the most abundant species in El-Outaya. Majority of the thrips are cosmopolitan in distribution and recorded as pest species, they can harm broad bean crop. These include Frankliniella occidentalis that may transmit Tospovirus.

Effect of Temperature, Relative Humidity and Natural Enemies on some Insect Pests Infesting Faba Bean Plants at El-Monofia Governorate

“…Thrips are among the most serious of these pests and are listed as a major insect pests in the Mediterranean region (Sexana, 1991). Thrips use their asymmetrical paired mouth parts to puncture cells on the leaf surface and then ingest or suck plant juices (Razi et al 2013). Thus, the present study aimed to investigate the effect of biotic and abiotic factors on population of cowpea aphid, A. craccivora and T. tabaci on faba bean plants.…”

Thrips (Thysanoptera) associated with two genetically modified types of linseed (Linum usitatissimum L.)

“…T. angusticeps was the dominant species irrespective of the type of oil flax used. It prefers flax but feeds on many other crops, like sugar beet, onion, peas, narrow-leafed lupin, broad bean, winter wheat and winter rye [10,21,41,44,51,52,58]. T. tabaci, which was the second important phytophagous species on oil flax, is an important pest of onion, other onion relatives, and several crops in most parts of the world [15,25,31,34,39,[41][42][43].…”

“…T. angusticeps is a polyphagous, widespread and common species in Europe. It prefers flax but feeds on many crops, like sugar beet, onion, peas, narrow-leafed lupin, broad bean, winter wheat and winter rye [10,21,41,44,51,52,58]. T. angusticeps has two generations per year in Europe [8,59].…”

Première observation de Thrips tabaci et de Frankliniella occidentalis sur les cultures sous serre en Algérie

“…Dans la région de Biskra, F. occidentalis a été déjà mentionné sur la fève ( Vicia faba ) par Razi et al . (). Près d'Alger (Nord algérien), Benmessaoud‐Boukhalfa et al .…”

“…Dans la r egion de Biskra, F. occidentalis a et e d ej a mentionn e sur la f eve (Vicia faba) par Razi et al (2013) S'il n'y avait le climat saharien tr es hostile et certaines pratiques culturales, le niveau d'infestation de ces solanac ees par ces thrips serait probablement plus important. Parmi ces pratiques, il y a surtout le d eplacement p eriodique des serres (chaque 3 ans), pour pallier aux probl eme de salinit e, et la d esinfection du sol par la solarisation (effet combin e du film plastique et des temp eratures maximales estivales, qui d epassent fr equemment les 50°C).…”
