Charipinae collected in different regions of Mexico have been studied. Twelve species are cited for the first time: Alloxysta arcuata (Kieffer, 1902), Alloxysta brevis (Thomson, 1862), Alloxysta castanea (Hartig, 1841), Alloxysta fuscicornis (Hartig, 1841), Alloxysta mullensis (Cameron, 1883) ; Alloxysta victrix (Westwood, 1833 ); Phaenoglyphis americanaBaker, 1896; Phaenoglyphis calvertiAndrews, 1978; Phaenoglyphis falcataAndrews, 1978; Phaenoglyphis stenosAndrews, 1978; Phaenoglyphis stricta (Thomson, 1877); and Phaenoglyphis villosa (Hartig, 1841). Three new species are described: Alloxysta evenhuisi Ferrer-Suay & Pujade-Villar n. sp., Alloxysta mexicana Ferrer-Suay & Pujade-Villar n. sp., and Alloxysta sarae Ferrer-Suay n. sp. The genera Alloxysta and Phaenoglyphis are cited for the first time from Mexico. A key to all Mexican Charipinae is given. New hosts and trophic relationships are presented for some species.

Objective: To examine the diversity of winged aphids in papaya (Carica papaya L.) crops and to determine the population fluctuation of vector species of the papaya ringspot virus (PRSV). Design/Methodology/Approach: We captured winged aphids by placing eight Moericke-type water traps (four green and four yellow). We conducted weekly samplings to locate plants with ringspot symptoms, record the abundance of vector species of PRSV, and document the progress of the disease. Results: We collected a total of n=694 individuals of 20 species, seven of which fell in the green traps and 19 in the yellow traps. The green traps registered the highest diversity value; however, the yellow traps captured the largest richness. Six of the captured aphids are reported as PRSV transmitters. The analysis of the population fluctuation of the vector species determined that A. spiraecola recorded two population peaks during the study: the first at week three, with 93 captured individuals; and the second (and highest) at week ten, with 316 individuals. PRSV was observed in the week seven in nine diseased plants. Full contagion (100%) was reached by week 44. Study Limitations/Implications: Developing strategies for preventing and controlling pest species and disease vectors crucially depends on the correct choice of methods to capture and monitor insect populations in crops. Findings/Conclusions: We can infer that vector species conduct short-distance migrations within the plantation. This inference is supported by the increased number of diseased plants.

ha permitido establecer 3 especies: I. chiriquense n. sp. (con la descripción de hembras ápteras y aladas) de Panamá, I. holmani n. sp. (con la descripción de hembras ápteras, aladas y de machos) e I. oaxacense n. sp. (con la descripción de ápteras) de México. Se describen también las vivíparas aladas y se mejora el conocimiento de las vivíparas ápteras de I. americanum. Se discute la ubicación genérica de las especies del género presentes en América. Se facilita la clave para la identificación de las hembras vivíparas ápteras de las especies americanas del género, que puede sustituir a la clave de Blackman & Eastop para las especies de pulgones que viven sobre plantas del género Cuphea P.Browne (Myrtales, Lythraceae) en el mundo.

Se realizaron muestreos de pulgones en tres huertas de naranja Valencia de los municipios de Hidalgo, Padilla y Victoria, Tamaulipas, desde septiembre de 1995 hasta abril de 1996 durante 12 fechas de colecta. Se muestrearon 15 árboles por huerta y se colectaron brotes infestados en cada uno de los tres estratos de altura de los árboles. Las especies de pulgones presentes fueron: Aphis gossypii (Glover), Aphis spiraecola (Patch), Aphis fabae (Scopoli) y Toxoptera aurantii (Boyer de Fonscolombe), presentando una distribución por contagio y siendo preferido el estrato medio del árbol. Se confirma la ausencia de Toxoptera citricida (Kirkaldy) durante el periodo de estudio. Los enemigos naturales fueron cuatro especies de Coccinellidae (Hippodamia sp., Cycloneda sp., Brachyacantha sp., y Stethorus sp.), dos de Syrphidae (Ocyptamies sp. y Pseudodorus clavatus Fabricius), una de Chrysopidae (Chrysoperla rufilabris Burmeister) y una de Chamaemyiidae (Leucopis sp.), Lysiphlebus testaceipes (Cresson) (Braconidae) como parasitoide primario, y Alloxysta megouzae (Ashm.) (Cynipidae) como parasitoide secundario.
