Occurrence records and new hosts of Gargaphia lunulata (Mayr) (Hemiptera: Tingidae) in the states of Acre and Paraná, Brazil.

Abstract

The occurrence of Gargaphia lunulata (Mayr) (Hemiptera: Tingidae) was observed in leaves of four host plants: rue (Ruta graveolens L.) and jack bean (Canavalia ensiformis (L.) DC) in an urban residential garden, in the municipality of Rio Branco, Acre State, Brazil and Crotalaria spectabilis (L.), jack bean and okra (Abelmoschus esculentus L. Moench) in a greenhouse, in the municipality of Londrina, Paraná State, Brazil. The colonies were found exclusively on the abaxial face of the leaves, causing chlorosis, wilting and early senescence of the same. Because G. lunulata is considered to be an important passion fruit pest in Brazil, the planting of the mentioned plant species, in intercropping or near to passion fruit crops, would not be recommended, since they could serve as plant species inoculum to passion fruit cultivation. Therefore, the occurrence of G. lunulata associated to R. graveolens and jack bean in Acre State; and C. spectabilis, jack bean, and okra, in Paraná State is record for the first time. In addition, the present work reports the first occurrence of this tingid to the States of Acre and Paraná and reports two new hosts for this insect, R. graveolens and C. spectabillis in Brazil.
