“…For this reason, it is convenient to use the water extract of R. raphanistrum, which, in addition, is not phytotoxic and reduces oviposition at concentrations of 60 mg mL -1 . Surprisingly, water and ethanolic extracts of A. artemisiifolia and acetonic extract of P. auritum at 3.5 mg mL -1 and water extract of T. officinale and ethanolic extract of R. raphanistrum at 3.5 to 4.0 mg mL -1 stimulated oviposition; this is probably in response to the stress caused in the female by sublethal concentrations and treating this privilege survival through a higher oviposition rate (Abdullah et al, 2006) (Table 4).…”

“…The reduction in oviposition rates in some insects is due to the disturbance in the activity of chemoreceptors or the integration of information during the process of search and host acceptance generated by pesticides and extracts (Umoru et al, 1996;Desneux et al, 2007). On the other hand, higher rates of oviposition are also associated with the fly's preference for plants with high contents of N, sugars, amino acids in the phloem, and low pH as was demonstrated in B. tabaci in cotton plants treated with different rates of fenvalerate and acephate (Abdullah et al, 2006).…”

In a search for sustainable options of greenhouse whitefly Trialeurodes vaporariorum (Westwood) management, the toxic and/or repellent potential of water, ethanolic, and acetonic extracts of Ambrosia artemisiifolia L. (Asteraceae), Comocladia engleriana Loes (Anacardiaceae), Piper auritum Kunth (Piperaceae), Raphanus raphanistrum L. (Brassicaceae), and Taraxacum officinale F.H. Wigg. aggr.* (Asteraceae) were evaluated. Repellency was assessed by the cylinder method (olfactometer), while toxicity and oviposition inhibition were assessed by the leaf immersion method. Acetonic extracts did not cause any repellent or insecticidal effect. In contrast, 200 mg mL -1 water and ethanolic extracts of R. raphanistrum and ethanolic extract of A. artemisiifolia had the highest repellent activity (76%, 72%, and 69%, respectively) although their activity decreased gradually over time. Ethanolic extracts of P. auritum (66%) and R. raphanistrum (56%) at 200 mg mL -1 were highlighted as being toxic, while the most effective in inhibiting oviposition were water extracts of R. raphanistrum (76.1%) and P. auritum (72.0%) and ethanolic extract of P. auritum (69.5%); however, concentrations lower than 60 mg mL -1 caused oviposition stimulation. Our results suggest that water and ethanolic extracts of R. raphanistrum and P. auritum represent a useful tool in integrated whitefly management.

“…En la evaluación de diversos insecticidas, se encontró que este producto no provoca reducción de azucares totales en las hojas tras su aplicación, por lo que el insecto no considera al hospedero como inadecuado para el desarrollo de su progenie (Abdullah et al, 2006). Sin embargo, son necesarios estudios en los que se determine el efecto en la fertilidad y subsecuentemente en el ciclo del insecto.…”

“…In the evaluation of various insecticides, it was found that this product does not cause reduction of total sugars in leaves after application, so that the insect does not consider the host as unsuitable for the development of their offspring (Abdullah et al, 2006). However, studies in which the effect on fertility are determined and subsequent monitoring in the cycle of the insect are required.…”

Los insecticidas químicos para controlar Trialeurodes vaporariorum West. han sido prácticamente la única herramienta utilizada, sin embargo la problemática global de contaminación ambiental y presión selectiva a insecticidas, ha fomentado un cambio en la forma de manejar las plagas más ecológicas y eficaces. El nim o neem Azadirachta indica es una opción como insecticidas botánicos, sus metabolitos ya se han comercializado en diferentes formulaciones, sin embargo es necesario evaluar su acción insecticida e insectistática. El objetivo de esta investigación fue comparar el efecto en la mortalidad, repelencia y oviposición de productos formulados de A. indica. En este estudio se probaron cuatro formulaciones a base de aceite de nim en adultos de T. vaporariorum. Los productos que mostraron la mortalidad más alta fueron Neem Oil Spray y PHC Neeem, a una concentración de 0.6 mg mL-1. El mejor efecto repelente fue de Neem Oil Spray (82.6%), PHC Neeem (72.3%), Biosave Neem (70.8%), y Neemix 4.5 (59.9%); los dos primeros muestran mayor persistencia con efecto similar a los 3 días de evaluación. El mejor inhibidor de la oviposición fue Neem Oil Spray (99.6% utilizando 1 mg mL-1), Biosave Neem (92.8%), PHC Neeem (82.6%), y Neemix 4.5 (57%). En contraste, Biosave Neem y Neemix 4.5 estimularon la oviposición en concentraciones de 0.01-0.3 mg mL-1 y PHC Neeem a 0.035 mg mL-1. La concentración de aceite en la formulación es determinante en el efecto, pues a mayor proporción, la formulación se hace más persistente, lo contrario la hace más polar y aumenta su capacidad sistémica.

“…For B. tabaci, variants have been distinguished based on host range (Abdullah et al 2006;Attique et al 2003;Bayhan et al 2006;Bedford et al 1994;Burban et al 1992;Bird 1957;Bird and Brown 1998;Butler and Brown 1985;Carabali et al 2005;Brown 1990, 1991;Costa et al 1991a, b;Costa and Russell 1975;Legg 1994Legg , 1996Maruthi et al 2001Maruthi et al , 2002Osmondi et al 2005;Sseruwagi et al 2006;ServinVillegas et al 2006;Simon et al 2003;Thompson 2003) life history traits (Bethke et al 1991;Costa et al 1991b;Demichelis et al 2005;Viscarret et al 2003), and other evidence for phenotypic variation, including differential virus transmission, which influences the epidemiology of viral outbreaks and their control (Brown et al , 2004aBrown and Bird 1996;Brown 2007;Legg et al 2002Legg et al , 2008.…”
