Potential use of Asteraceae extracts to control Spodoptera frugiperda (Lepidoptera: Noctuidae) and selectivity to their parasitoids Trichogramma pretiosum (Hymenoptera: Trichogrammatidae) and Telenomus remus (Hymenoptera: Scelionidae)

Soil organisms associated to the weed suppressant Crotalaria juncea (fabaceae) and its importance as a refuge for natural enemies

“…This predator is common in maize and sorghum where it lay eggs and preys on the main pests, Diatraea saccharalis (Lepidoptera: Crambidae) and Spodoptera frugiperda (Lepidoptera: Noctuidae) (Figueiredo et al, 2006;Wyckhuys & O'Neil, 2007;Lima et al, 2010). However, the higher abundance of natural enemies in organic agriculture is also due to lower levels of chemical application in these areas (Birkhofer et al, 2008;Tavares et al, 2009). Natural enemies in C. juncea demonstrate the importance of the culture as a refuge for insects and the need for research development on the crops, either in outline or in succession with annual or perennial crops, in order to improve the efficiency of similar agricultural regions.…”

Effect of Hexaflumuron on Gustation and Reproduction of Adult Boll Weevil

“…These solutions were shaken with a Branson 2510 sonifier for 220 min in SET DEGAS and homogenized with a Fisher Vortex Genie 2™ shaker at "speed eight" for 10 min (Tavares et al 2009). …”

“…The extracts from several plant parts (bark, flowers, leaves, roots, seeds, and stems) of the families Euphorbiaceae, Fabaceae, Lamiaceae, Monimiaceae, Verbenaceae, and Zingiberaceae have shown efficacy against the adults and larvae of S. zeamais (Fouad et al 2012;Tavares et al 2013a). However, only a few bioprospection studies of compounds useful as natural insecticides have been carried out (Tavares et al 2009(Tavares et al , 2013b.…”

Effects of botanical insecticides on the instantaneous population growth rate of Aphis gossypii Glover (Hemiptera: Aphididae) in cotton

“…Several authors evaluated the performance of insecticides and acaricides on pests and natural enemies, using the instantaneous population growth rate (ri), among which are the aphid Acyrthosiphon pisum (KRAMARZ et al, 2007), Myzus persicae and the ladybug Eriopis connexa (VENZON et al, 2007), white mite Polyphagotarsonemus latus (VENZON et al, 2006), spider mite Tetranychus urticae (KIM et al, 2006), and phytoseiid predator Phytoseiulus persimilis (TSOLAKIS; RAGUSA, 2008), parasitoids Ttrychogramma pretiosum and Telenomus remus (TAVARES et al, 2009), and the coffee red mite (Olygonicus ilicis) (MOURÃO et al, 2004).…”
