Resumen

Summary A three-season field evaluation showed that eggplants (Solanum melongena) are very tolerant to damage caused by the two-spotted spider mite, Tetranychus urticae. Although large numbers of the predacious mites, Neoseiulus fallacis or Phytoseiulus persimilis were released, biological control of the two-spotted spider mite could not be sustained in the field. Based on a preliminary comparison of yield in both sprayed and unsprayed plots and on a three-year qualitative assessment, a tentative action threshold of 600 two-spotted spider mites per leaf would not decrease yield and would reduc

Abstract This test was designed to compare ABG-6277A to Kelthane for control of two-spotted spider mite. Delta Pine 50 was planted 8 May in plots 8 rows × 40 ft long. The plots were arranged in a randomized complete block design with 4 replications. The plots were infested with TSSM by placing one infested bean plant every 3 steps along the center 2 rows of each plot on 29 Jun. Mite predators were reduced by weekly sprayings of Asana 0.025 lb (AI)/acre beginning on 28 Jun. Treatments were applied 11 and 18 Jul with a Hi Boy sprayer with tips every 20 inches delivering 10 gpa. The percent mite

Buddleia taxa were assessed for two-spotted spider mite (Tetranychus urticae Koch) resistance using a leaf disk bioassay, a novel shell vial bioassay and a field trial. Leaf pubescence and chemistry were examined for their role in two-spotted spider mite resistance. Results from bioassays and field sampling identified highly resistant taxa including B. fallowiana Balif. `Alba' and B. davidii × B. fallowiana Franch. `Cornwall Blue' as well as susceptible taxa including B. davidii Franch. `African Queen' and B. lindleyana Fort. ex Lindl. `Gloster'.

Abstract Potentilla fruticosa L. (Rosaceae Juss.) is one of the most popular deciduous shrubs cultivated in Poland. Among pests identified so far on P. fruticosa, a serious threat is caused by two-spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae). During three-year study, the occurrence of two-spotted spider mite T. urticae on four cultivars of P. fruticosa: ‘Goldfinger’, ‘McKay’s White’, ‘Uman’ and ‘Pink Beauty’ grown in field conditions was compared. While conducting experiment, weather conditions were monitored. The number of eggs and motile forms of two-spotted spider mit

Resumen

Buddleia species are attractive ornamental shrubs whose major cultural problem is infestations of the two-spotted spider mite. Two factors, drought stress and leaf pubescence, were examined for their effects on spider mite infestations. Drought stress was examined by placing 20 plants into a randomized block design and stressing ten of the plants. No differences in mite life parameters were found, although there was more uninfested area in nonstressed plants. This was probably due to the nonstressed plants' ability to outgrow the spider mite infestation. Leaf texture was examined by placing fo

Powdery mildew and two-spotted spider mite are detrimental to strawberry plants and are controlled with traditional pesticides. To accommodate consumer demand, eco-friendly methods of pest control are required. Strawberries were cultivated (in soil and in a hydroponic system) for two years, and ultraviolet B (UV-B) irradiation was used as an alternative pest control during the harvesting season. Three varieties were grown (Seolhyang, Kingsberry, and Durihyang), and four UV-B lamp/mulch (black, green, and light reflection sheet [LRS]) combinations were used during harvesting: UV-B+black or gree

Resumen

The two spotted spider mite, Tetranychus urticae Koch L. (Acari: Tetranychidae), is a plant pest that can lead to severe economic losses in open field cucumber cultivation. Between 2017 and 2019 we studied the abundance of spider mites in the soil to estimate the potential infestation pressure of soil colonizing spider mites. The spider mites were heterogeneously distributed in small concentrations in the soil. Soil colonizing spider mites did not affect spider mite abundance on plants and reversed. We observed that spider mite migration occurred primarily from the edge of the field adjacent t

Resumen

Garden strawberry (Fragaria x ananassa Duch.) is an important commercial berry crop. Its productivity depends on the adaptive potential of the cultivar and is limited by the degree of exposure to unfavorable abiotic and biotic factors characteristic of a particular climatic zone. The present work studies the resistance of garden strawberry cultivars with diff erent ripening periods to damage by the two-spotted spider mite (Tetranychus urticae Koch.) when grown under simulated conditions of a climatic chamber. Cultivars were observed to respond differently to simulated extreme growing condition

The present investigation was undertaken to evaluate the okra germplasm and identify the potential sources of two spotted spider mite resistance that can be exploited for the improvement of commercial okra. Based on the mean mite population and damage score six entries out of the 58 entries namely Kasturi bhendi, (R), Dharmapuri local (MR), Parbani Kranti (MR), Pusa Sawani (MR), COBhH1 (MR) and Mahyco 10 (S) with varied levels of resistance were identified.

ABSTRACT One of the major problems in cultivation of tomato is the occurrence of pests and diseases. The objective of the research was to select genotypes from the second generation of the first backcross (F2BC1) between the tomato cultivar for processing S. lycopersicum (cv. Redenção) and the wild access S. habrochaites var. hirsutum (PI-127826), with high levels of zingiberene (ZGB), resistant to the twospotted spider mite Tetranychus urticae (Acari: Tetranychidae). From the F2BC1 population. The ZGB content was quantified and five plants with high zingiberene selected (RVTZ 2011-079-117, RV

Resumen

Abstract Cotoneaster growing in 1-gal (3.9 1) containers in a greenhouse at the main OARDC campus were used to evaluate efficacy of selected pesticides against two-spotted spider mites. A CO2 compression sprayer at 20 psi with a single Teejet SS8004 flat-fan nozzle was used to apply treatments to runoff. Infested plants were selected at random and placed in groups of 3 replicates/treatment. The first application was applied to all plants 25 Sep; the second application to selected plants 2 Oct. Plants were hand-watered every Mon, Wed, and Fri throughout the test period. Treatments were evaluate

Resumen

The two-spotted spider mite Tetranychus urticae is a dangerous polyphagous pest of agricultural and ornamental plants. In a commercial greenhouse treated with acaricides or biological control using predatory mite Phytoseiulus persimilis individual varieties of roses differed significantly in terms of the average annual infestation by the pest mite. On the poorly populated rose varieties, the biological control agent application was more effective as compared to the acaricides. To effectively control the pest, the required predatory mite rates were 4.6–8.7 times higher on varieties with a minim

Carnation holds a prominent place and a good market among the various cut flowers in Himachal Pradesh, India, but it can be severely attacked by the two spotted spider mite, Tetranychus urticae Koch. Indiscriminate use of pesticides has led to development of resistance in this species, affected human health and caused environmental pollution. The determination of safer and more cost effective and eco-friendly alternative approaches for the management of this pest is desirable.

The two-spotted spider mite, Tetranychus urticae Koch, is one of the main strawberry pests in Brazil and many other countries. The objective of this study was to compare the resistance of eight strawberry genotypes (‘Albion’, ‘IAC Guarani’, ‘IAC Princesa Isabel’, ‘Oso Grande’, IAC T-0104, IAC 12, IAC 4 and IAC 1.13) to the two-spotted spider mite, by assessing injury level, biological parameters and host preference of the mite. To facilitate the interpretation of the results, leaf trichomes of each genotype were quantified. Thirty days after the artificial infestation of the genotypes with the

ABSTRACT The strawberry is susceptible to several pests which cause a reduction in productivity. The use of mechanisms which repel or prevent these pests to establish, represent a sustainable environmental technology to reduce the frequency of agrochemical use. In this context, the aim of this study was to evaluate the effect of salicylic acid (SA) on resistance induction against two-spotted spider mite in strawberry cultivars (Aromas and Sweet Charlie). Five concentrations of SA (0, 25, 50, 75 and 100 mg L-1) were tested in order to verify the antixenosis effects. In SA concentration of 50 mg
