Feeding and oviposition of Diaphorina citri (Hemiptera: Liviidae) on Helietta apiculata (Sapindales: Rutaceae): A potential host?
Keywords:
Alternative host, Asian citrus psyllid, insect-plant interaction, huanglongbing.Abstract
This study evaluated the survival and fertility of the huanglongbing vector Diaphorina citri Kuwayama (Hemiptera: Liviidae) on two species of the family Rutaceae, Murraya paniculata (Sapindales: Rutaceae) and Helietta apiculata Benth. (Sapindales: Rutaceae). Females of D. citri oviposited on both hosts. The survival of D. citri was similar on both hosts until day 7 of confinement on the plants. H. apiculata can support D. citri in regions where the vector's main host (orange jasmine) or citrus groves are absent, a potential factor in the dispersal and epidemiology of huanglongbing.

Sumário
Esse estudo avaliou a sobrevivência e fertilidade de Diaphorina citri Kuwayama (Hemiptera: Liviidae) em 2 espécies da família Rutaceae, Murraya exotica L. (Sapindales: Rutaceae) (falsa-murta) e Helietta apiculata Bentham (Sapindales: Rutaceae). Fêmeas de D. citri ovipositaram em ambos hospedeiros. A sobrevivência de D. citri foi similar em ambos hospedeiros até o sétimo dia de confinamento nas plantas. Helietta apiculata pode auxiliar na sobrevivência do vetor em regiões onde seu principal hospedeiro (M. exotica) ou pomares cítricos são escassos, sendo este, um importante fator na dispersão e epidemiologia do huanglongbing.
