El piojo harinoso Phenacoccus herreni Cox & Williams (Sternorrhyncha: Pseudococcidae) es un insecto plaga que afecta a la yuca Manihot esculenta Crantz (Euphorbiaceae) especialmente durante la estación seca, observándose un aumento poblacional. Este fenómeno puede responder a cambios bioquímicos en las hojas de la planta, inducidos por déficit hídrico que favorecen el desarrollo del insecto. Con el fin de verificar la ocurrencia de este hecho fue necesario empezar por conocer su comportamiento alimenticio. Se realizó microscopía electrónica de barrido y óptica de contraste de fases, del aparato bucal del insecto y se estudió su actividad de alimentación por electropenetrografía (EPG). Además, se evaluaron el desarrollo biológico, la tasa reproductiva del insecto y la composición aminoacídica de hojas infestadas provenientes de plantas de yuca con regímenes de riego diferenciales (irrigación normal y deficiente). Adicionalmente, mediante una dieta artificial se evaluó la influencia sobre el desarrollo de P. herreni de los aminoácidos cuya proporción se vió aumentada en plantas sometidas a estrés hídrico. Los resultados permitieron verificar que P. herreni es un insecto principalmente floemófago caracterizado por presentar un aparato bucal pricador-chupador, durante todo el ciclo biológico de las hembras. Los insectos macho presentan este aparato bucal sólo hasta el segundo ínstar, posteriormente se atrofia y dejan de alimentarse. Por lo que se sugiere que son las hembras de P. herreni, al conservar su aparato bucal y alimentarse de la savia del floema durante todo su ciclo de vida, las que causan el mayor deterioro a los cultivos de yuca, por lo tanto los estudios siguientes se realizaron con hembras. El estrés hídrico en las plantas provocó una reducción en la duración del desarrollo de las hembras y un incremento en su fecundidad, en su tasa intrínseca de crecimiento natural (rm) y en su peso. |

| Summary, etc |
The cassava mealybug Phenacoccus herreni Cox & Williams (Sternorrhyncha: Pseudococcidae) is an important pest of cassava, Manihot esculenta Crantz (Euphorbiaceae), especially during drought, when insect population's increase. This phenomenon might be a response to biochemical changes in cassava leaves induced by water deficiency, which enhances insect development. In order to verify this phenomenon it was first necessary to study its feeding behavior. Observation of the mouthpart by scanning electron microscopy and fase contrast microscopy were carried out and the feeding activity was studied by electropenetrography (EPG). Insect biological development and reproductive rate, and also infested leaf aminoacid composition from cassava plants grown with differential irrigation levels (well watered and deficiently watered) were evaluated. The influence on P. herreni development of the aminoacids that increased their proportion in water stressed plants was evaluated using an artificial diet. The results showed that P. herreni is mainly a phloemophagous insect with piercing-sucking mouthpart that is present in females throughout their life cycle. Male insects showed the same mouthpart only till the second ínstar. The fact that the females maintain their piercing-sucking mouthpart and they feed on phloem sap throughout their life cycle, we suggest that the females are more responsible for cassava damage and therefore subsequent studies were done oil females. Water stress ill plants induced a reduction in the duration on female development and all increase ill fecundity, intrinsic natural growth rate (rm) and in weight. |
