“…Similar results were reported by Rosas-Garcia et al (2009) that the adult stage of C. montrouzieri was the most efficient predatory stage as compared with the other development stages of the predator. This is due to the fact that adult beetles have a greater longevity than their larval instars.…”

“…The reason for lower predatory efficiency of first instar C. montrouzieri might be due to its small size, compared with other development stages of the predator. Previous research by Rosas-Garcia et al (2009), who studied the predatory efficiency of C. montrouzieri on P. citri, reported that the first instar larvae preyed on significantly fewer mealybugs as compared with other development stages of the predator.…”

“…Earlier investigations (Rosas-Garcia et al, 2009;Atif et al, 2011) evaluated different life stages of C. montrouzieri against citrus mealybug and concluded efficiency of all stages. But earlier instar had less demand to consume the administered feed, so these 1 st and 2 nd instars consumed lesser amounts of mealybugs whereas later developmental stages such as 3 rd instar and adults showed more thrust of food.…”

“…De acuerdo a Holling (1959) a bajas densidades de la presa, el depredador gasta más tiempo en la búsqueda, mientras que a altas densidades de la presa, el depredador gasta más tiempo en el manejo, sin embargo C. montrouzieri ha sido considerado como un depredador muy voraz ( -García et al 2009), lo que concuerda con los resultados de este estudio al demostrar una depredación cercana del 100% con densidades variables de la plaga. Esto es posible por su condición de depredador oligófago que generalmente le permite responder mejor que los polífagos a los cambios en las densidades poblaciones de las plagas (van Emden y Service 2004) y a las cuales detecta más fácilmente por estímulos visuales y olfatorios (Heidari y Copland 1992, engonca et al 1995.…”

“…A pesar del amplio uso de C. montrouzieri como una herramienta de control biológico para CRH, existe poca o nula información relacionada con su comportamiento de depredación. Hasta la fecha se sabe que ataca a la CRH durante la etapa larvaria y adulta y ha mostrado ser altamente efectivo cuando las poblaciones son mayores a 20 individuos por brote ((Rosas-García et al 2009, Afifi et al 2010. Durante el periodo larvario, C. montrouzieri consume de 1,800 a 1,900 huevecillos, de 250 a 268 ninfas y de 25 a 30 hembras adultas de CRH, mientras que en la etapa adulta pueden consumir de 3,700 a 4,000 huevecillos, de 750 a 800 ninfas y de 180 a 190 hembras adultas (Valencia-Luna et al 2007).…”
