Control failure likelihood and spatial dependence of insecticide resistance in the tomato pinworm, Tuta absoluta.
TLDR
Insecticide resistance in field populations of the tomato pinworm prevails for the insecticides nowadays most frequently used against them-the chitin synthesis inhibitors (diflubenzuron, triflumuron and teflubenzur). Expand
The tomato borer Tuta absoluta in South America: pest status, management and insecticide resistance
TLDR
The sex pheromone of T. absoluta was identified, confirmed and synthesized in the late 1990s and it is currently used for detection and monitoring of this species, but improved sampling plans are still necessary for its use in decision-making regarding insecticide use. Expand
Cartap resistance and synergism in populations of Tuta absoluta (Lep., Gelechiidae)
TLDR
Resistance to cartap was observed in all populations when compared with the standard susceptible population, suggesting a major involvement of cytochrome P450‐dependent monooxygenases as a cartap resistance mechanism in these populations of T. absoluta. Expand
Insecticide resistance in populations of Tuta absoluta (Lepidoptera: Gelechiidae)
TLDR
Control failures of insecticides used against the tomato leafminer Tuta absoluta (Meyrick) in Brazil led to the investigation of the possible occurrence of resistance of this insect pest to abamectin, cartap, methamidophos and permethrin. Expand
Compounds from Ageratum conyzoides: isolation, structural elucidation and insecticidal activity.
TLDR
The complete assignment of (13)C NMR to 5,6,7,8,3'-pentamethoxy-4', 5'-methylenedioxyflavone was successfully made for the first time and did not show any insecticidal activity against the four insect species tested. Expand
Ecological Life Table of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)
TLDR
An ecological life table was constructed, aiming to determine the critical stages and key mortality factors of Tuta absoluta (Lepidoptera: Gelechiidae), and Predators were responsible for 79.4% of larval mortality. Expand
Plant compounds insecticide activity against Coleoptera pests of stored products
TLDR
The objective of this work was to isolate, identify and assess the bioactivity of insecticide compounds present in these plants, against Coleoptera pests of stored products: Oryzaephilus surinamensis L. (Silvanidae), Rhyzopertha dominica F. (Bostrichidae) and Sitophilus zeamais Mots (Curculionidae). Expand
Impact of integrated pest management on the population of leafminers, fruit borers, and natural enemies in tomato
TLDR
IPM was the most efficient system of pest control due to presenting similar productivity and 65.6% less pesticide applications than in the calendar and when action thresholds were achieved. Expand
Toxicity of insecticides to the sweetpotato whitefly (Hemiptera: Aleyrodidae) and its natural enemies.
TLDR
The present results suggest that abamectin at 100% FR may decrease B. tabaci field populations but can still be harmless to predators. Expand
Resistance of 57 greenhouse-grown accessions of Lycopersicon esculentum and three cultivars to Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae).
TLDR
Evaluated resistance to Tuta absoluta (Meyrick) by antixenosis on 57 Lycopersicon esculentum Mill to determine possible chemical causes of resistance, hexane extracts were analyzed at day 90 by gas chromatography/mass spectrometry and the major peaks identified by a mass spectral database using similarity index.
