Bacillus thuringiensis Survey in Brazil: Geographical Distribution and Insecticidal Activity Against Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)
A total of 3408 strains of Bacillus thuringiensis were collected from 1448 soil samples in 10 Brazilian states, four different geographical regions, covering 96 counties. These strains were evaluated against Spodoptera frugiperda (J.E. Smith) larvae. Only 62% killed between 81% and 100% and 1758 caused no mortality. Highest proportion of efficient strains (larval mortality above 75%) was found ...
متن کاملEffect of triterpenoids and limonoids isolated from Cabralea canjerana and Carapa guianensis (Meliaceae) against Spodoptera frugiperda (J. E. Smith).
The activities of two triterpenoids, ocotillone and cabraleadiol, and four limonoids, methyl angolensate, 3-beta-deacetylfissinolide, 7-deacetoxy-7-oxogedunin, and beta-photogedunin, isolated from arillus of Carapa guianensis and fruits and seeds of Cabralea canjerana (Meliaceae), were evaluated against the fall armyworm Spodoptera frugiperda. Gedunin was used as a positive control. 7-Deacetoxy...
متن کاملPlasmid patterns of efficient and inefficient strains of Bacillus thuringiensis against Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae).
Bacillus thuringiensis harbors genes encoding Cry proteins found in chromosomes or plasmids of different sizes (4-150 Mb). Although the smaller plasmids are more abundant in B. thuringiensis, their specific function is unknown. As for the megaplasmids, their main recognized function is to harbor cry genes, although the sequencing of some of these plasmids indicates the occurrence of other impor...
متن کاملBioactivity of Carica papaya (Caricaceae) against Spodoptera frugiperda (Lepidoptera: Noctuidae).
The composition of a chloroform seed extract of C. papaya was determined by GC-MS. Nineteen compounds were identified, with oleic (45.97%), palmitic (24.1%) and stearic (8.52%) acids being the main components. The insecticidal and insectistatic activities of the extract and the three main constituents were tested. Larval duration increased by 3.4 d and 2.5 d when the extract was used at 16,000 ...
متن کاملAcetylcholinesterase and insect growth inhibitory activities of Gutierrezia microcephala on fall armyworm Spodoptera frugiperda J.E. Smith.
From the aerial parts of Gutierrezia microcephala (Asteraceae), four oxyflavones were isolated, namely 5,7,2'-trihydroxy-3,6,8,4',5'-pentamethoxyflavone (1); 5,7,4'-trihydroxy-3,6,8-trimethoxyflavone (2); 5,7,2',4'-tetrahydroxy-3,6,8,5'-tetramethoxyflavone (3); 5,2'-dihydroxy-3,6,7,8,4',5'-hexamethoxyflavone (4), and an ent-clerodane, bacchabolivic acid (5). Compounds 1-5, the synthetic methyl ...
