Cnidoscolus chayamansaTyphlocybinaeEmpoascafitoplasmas. With the aim of identifying the presence of phytoplasmas in insects and leaves, forty leafhopper adults and 50 leaves of three plants with symptoms associated with phytoplasmas, were collected at the municipality of10 de Octubre, Havana, from February to April For leafhopper taxonomical identification by using dichotomic keys, they were mounted on flat slides under a Stemi DV4 stereo microscope and observed under an AxioLab.

A1 microscope with a monitor and camera attached. The profiles obtained were compared with phytoplasma positive controls from Catharanthus roseus L. The leafhoppers identified were Empoasca canavalia DeLong and Empoasca papayae Oman, and the presence of phytoplasma was found in leaves with symptoms as well as in the insects. The presence of these two leafhopper species and phytoplasmas in chaya and insects are the first reports in Cuba.

Cnidoscolus chayamansaTyphlocybinae, Empoascaphytoplasmas. En Cuba se considera, popularmente, como una planta medicinal.

En la literatura consultada se hace referencia a la presencia en las plantas de Meloidogyne incognita raza 2 9del mosaico potexvirus de la yuca 10 y del fitoplasma amarillo de la chaya Los selectovas pertenecen a Hemiptera y representan un grupo ampliamente distribuido en el mundo. Las preparaciones se observaron al Microscopio AxioLab. UU 28 y se compararon con los controles positivos de los fitoplasmas obtenidos de plantas de Catharanthus roseus L.

En ambos casos con numerosas exuvias. Especie del tipo 1. Promedio de 3,2 esrructuras. No se observan el apodema tergal 1S Figura 1 a. La espina media dorsal del segmento 10 es moderadamente grande, forma un plato redondeado sin espuelas, solamente ligeramente esclerosadas e inconspicuas. El aedeago, en aspecto lateral, tiene una columna preatrio robusta con 3 procesos que salen del atrio y se extienden hacia el dorso.

Las placas subgenitales presentan numerosas setas que se han clasificado en grupos. Las diferencias con E. Diversos autores describen que parten del aedeago dos procesos 21, En realidad se observan 3, tal como se indica en E.

Especie del tipo 2: Amarillo verdoso; la corona, el pronoto y el escuto con manchas poco conspicuas. Promedio de 2, mm. El terguito 9 es una banda transversa de donde parten 2 apodemas en forma de V. Presenta el apodema 1S similar a los de las especies del complejo Empoasca fabae Harris Figura 2 a, e. La espina media dorsal es elongada, recta, con el cuarto apical estrecho y doblado, muy esclerosada Figura 2 b,c.

Las placas subgenitales separadas desde la base, lameliformes. Estos resultados ratificaron la presencia de fitoplasmas en plantas de chaya y en los insectos asociados a esta planta en las condiciones de Cuba.
