Nova planta hospedeira de Leptoglossus zonatus (Dallas) (Heteroptera: Coreidae)

Abstract

The coreid bug Leptoglossus zonatus (Dallas) is an important pest that can feed on several economically important plants such as corn, soybean, sorghum, cotton, among others. In Campinas, São Paulo state, Brazil, nymphs and adults of L. zonatus have been found mainly on corn Zea mays L. In field work carried out during the month of May, at the end of the vegetative cycle of corn, adults and nymphs of L. zonatus were observed feeding on Spathodea campanulata Beauv (Bignoniaceae), a tree of African origin widely used in urban green belts, parks and street in Brazilian cities.It is possible that L. zonatus can use the plant S. campanulata as an alternative food resource during the periods when corn is not present or is not at the right vegetative stages.

Leaf-Footed Bugs (Coreidae)

“…Corn seeds were far preferable for rearing than pods of either legume, and this insect is abundant in corn fi elds in Brazil (de Souza and Amaral 1999a ;Panizzi 2004b ). An African tree widely planted in greenbelts, Spathodea campanulata Beauv (Bignoniaceae), supports adults and nymphs and may serve as an alternate host (de Souza and Amaral 1999a ). The entire life cycle can also be completed on physic nut; instar duration data, nymphal measurements, and reproductive parameters have been determined for this host plant (Grimm and Somarriba 1999 ).…”

Records of Two Pest Species,Leptoglossus zonatus(Heteroptera: Coreidae) andPachycoris klugii(Heteroptera: Scutelleridae), Feeding on the Physic Nut,Jatropha curcas, in Mexico

“…L. zonatus is distributed throughout the Americas (Allen 1969), and is a polyphagous species with a wide range of hosts (Grimm 1999;Schaefer & Panizzi 2000). Souza & Amaral Filho (1999) mention that this true bug feeds on different species of plants belonging to 14 families, including economically important crops such as corn, sorghum, cotton, tomato, avocado , soya beans, lima bean, guava, pomegranate, melon, cashew nut, pitaya, passion fruit, date, cashew apple, peach, watermelon, Satsuma tangerine and oranges (Essig 1926;Quayle 1938;Panizzi 1989;Kubo & Batista Filho 1992;Zucchi et al 1993;Matrangolo & Waquil 1994;Jackson et al 1995;Raga et al 1995;Grimm & Maes 1997;Mitchell 2000;Schaefer & Panizzi 2000;Souza Filho & Costa 2003;Henne et al 2003). It also feeds on some ornamental plants such as the African Tulip, Spathodea campanulata Beauv.…”

“…It also feeds on some ornamental plants such as the African Tulip, Spathodea campanulata Beauv. (Souza & Amaral Filho 1999), Desert Willow, Chilopsis linearis (Cav.) Sweet (Jones 1993) both in Lamiales: Bignoniaceae, and the Chinese tallow tree, Triadica sebiferum (L.) (Euphorbiaceae) (Henne et al 2003).…”

Ciclo de vida y análisis de riesgo climático de Leptoglossus zonatus Dallas (Hemiptera: Coreidae) para las zonas productoras de sorgo en el estado de Morelos, México

“…También se ha reportado sobre algunas plantas ornamentales como el tulipán africano Spathodea campanulata Beauv. (Souza & Amaral Filho, 1999), el sauce del desierto Chilopsis linearis (Cav.) Sweet (Jones, 1993) y el árbol del sebo Triadica sebiferum (L.) (Euphorbiaceae) (Henne et al, 2003).…”

“…Para el control de L. zonatus, se utilizan tradicionalmente insecticidas químicos, enemigos naturales (Marchiori, 2002, Souza & Amaral-Filho, 1999) y hongos entomopatógenos; sin embargo, el uso de este último no se reporta a gran escala (Grimm & Guharay, 1998). El análisis de riesgo es una herramienta que ayuda a tomar la mejor decisión para el manejo de plagas.…”
