the two-spotted spider mite, tetranychus urticae koch, is a polyphagus pest which infests wide range of field, garden and greenhouse crops worldwide. pesticide applications against this pest have caused development of resistance, undesirable effects on non target organisms and environment and secondary pest outbreak. in recent years, herbal essential oils have received attention as natural plan...

During this survey in southeastern France, there were found three new alien spider mites species: Aponychus corpuzae on Phyllostachys sp. and Semiarundinaria yashadake; the Persea mite Oligonychus perseae americana most probably also Vitis vinifera; Stigmaeopsis nanjingensis S. yashadake. In connection with records of A. corpuzae, we propose an identification key for world species genus Aponych...

Abstract Background The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a major pest of strawberry. It was necessary to control this mite that can reducing the quality and quantity fruits. In regard, effect ZORO acaricide, Neoseiulus californicus (McGregor) Amblyseius swirskii Athias-Henriot for suppressing naturally occurring T. populations on three strawberry cult...

Surveys of Tenuipalpidae and Tetranychidae were conducted at three locations in Latakia governorate, Syria, 2021. Eight species collected; four flat mite which Aegyptobia beglarovi, Cenopalpus lineola, Pentamerismus juniperi new records for Syria; spider among Petrobia (Mesotetranychus) tunisiae represented a record. A tetranychid species, Bryobia (Lyobia) hadizeni sp. nov., collected from Cali...

fourteen accessions and cultivars of lycopersicon spp. were studied to evaluate their resistance to two-spotted spider mite, tetranychus urticae koch, under laboratory and greenhouse conditions. in vitro studies were carried out using thumbtack and leaf disk bioassays. lycopersicon hirsutum and l. pennellii accessions supported more mites on the tack. the highest number of eggs (5.15 â± 0.48 eg...

ABSTRACT: The spotted spider mite, Tetranychus urticae (Koch, 1836), is one of the most important pests strawberry production systems worldwide. Because plant resistance an integrated management strategy, present study investigated effects 12 genotypes on biological characteristics this pest under laboratory conditions (25 ± 2 °C and RH 60 10%; 12:12-hour photophase). experiment was carried usi...

A bacterial isolate from soil, designated as TB-2125 had a unique pattern of multiple resistance to aminoglycoside antibiotics (AG) and produced new nucleoside antibiotics. Taxonomic properties of this strain fell into those of Bacillus circulans, providing unique characteristics such as strict susceptibility to acidic pH, motility of colony as well as multiple AG-resistance. Two new antibiotic...

arthropod development is affected by temperature. knowledge of relationship between temperature and mite developmental rates is useful in biological and ecological studies. effect of six constant temperatures (15, 20, 25, 30, 35, 40 ) on developmental rate of all stages of two-spotted spider mite, tetranychus turkestani ugarov & nicolski, were investigated under laboratory conditions at 55 10% ...

The experiment was conducted to study the effectiveness of four commonly used chemicals viz., deltamethrin, cypermethrin, malathion and sulphur against two-spotted spider mite (TSSM), Tetranychus urticae Koch on potted bean plants and on excised leaf discs. Mite population remained significantly lower in all treated plots except malathion treatment. The population of T. urticae differed signifi...
