Population suppression of Ceratitis capitata (Wiedemann) on table grapes using toxic baits Anais da ABC (AABC)
BARONIO,CLÉBER A.; BERNARDI,DANIEL; PARANHOS,BEATRIZ A.J.; GARCIA,FLÁVIO R.M.; BOTTON,MARCOS.
Abstract To provide alternatives to the use of spraying synthetic insecticides in C. capitata management, was evaluated the effect of “attract and kill” toxic baits on population suppression of C. capitata in three commercial areas producing table grapes. Toxic baits of Gelsura™ (4.5 L ha-1) and Success™ 0.02 CB (4.0 L ha-1) resulted in lower population levels of C. capitata adults in monitoring traps after five sequential applications at weekly intervals during the maturation period of the grapes when compared with control plots with or without insecticidal spray. In addition, plots with Gelsura™ and Success™ 0.02 CB applications showed a significant reduction in damage (%) by C. capitata on grape berries and grape bunches when compared with control plots...

Synergistic potential of dillapiole-rich essential oil with synthetic pyrethroid insecticides against fall armyworm Ciência Rural

ABSTRACT: The objective of this study was to evaluate the synergy and response homogeneity of the Spodoptera frugiperda larvae population to the Piper aduncum essential oil in combination with pyrethroid insecticides (alpha-cypermethrin, beta-cypermethrin, fenpropathrin, and gamma-cyhalothrin) compared to piperonylbutoxide (PBO) as positive control. Synergism (SF) comparisons were obtained using lethal concentration (LC50) and lethal dose (LD50) ratios of insecticides individually and in their respective synergistic combinations with essential oil and PBO. Dose/concentration-mortality slope curves were used to establish relative toxicity increase promoted by synergism. They also determined homogeneity response. Residual contact revealed significant...
