Canavalia ensiformis is a Fabaceae used for soil conservation and control of weeds. The objective of this study was to identify gall wasps of C. ensiformis at Guerrero, Mexico. A survey was done in June 2022 in a crop of C. ensiformis planted to provide cover for Zea mays L. plots at Anahuac, San Marcos, Guerrero, México. Abnormal galls were found on several organs of the plants, especially the branches. Three branches from 10 plants were gathered, put into paper bags, labelled, and transported in polystyrene containers to Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP) for rearing wasps. Adults were identified based on morphological characteristics. C. ensiformis was reported for the first time as an alternate host of wasps of the genus Eurytoma. Further studies of the genus and species identification using molecular techniques are needed. [ABSTRACT FROM AUTHOR]

El pulgón amarillo, Melanaphis sacchari (Zehntner), se detectó en México en 2013 y se ha dispersado a diversas regiones productoras de sorgo, Sorghum bicolor (L.) Moench, causando daños del 30 al 100%. Se evaluaron en campo insecticidas de diferente modo de acción en dos experimentos que mantuvieron la densidad por abajo del umbral económico establecido de 50 pulgones por hoja. A los 28 días después de la aplicación, imidacloprid sulfoxaflor, flupyradifurone, pymetrozine, spirotetramat, y afidopyropen presentaron las menores densidades de pulgón amarillo. Esta información es relevante, ya que conocer la efectividad de insecticidas con diferente modo de acción permite utilizar los más efectivos y que puedan integrarse con otras medidas que se implementen en el manejo de M. sacchari. The sugarcane aphid, Melanaphis sacchari (Zehntner), was detected in Mexico during 2013 and has dispersed to various sorghum ( Sorghum bicolor (L.) Moench)-producing regions, causing damage from 30 to 100%. Insecticides with different modes of action were evaluated in two experiments in the field, maintaining abundance below the established economic threshold of 50 aphids per leaf. Fewest sugarcane aphids were found 28 days after treatment with imidacloprid, sulfoxaflor, flupyradifurone, pymetrozine, spirotetramat, and afidopyropen. This information is relevant, because knowing the effectiveness of insecticides with different modes of action allows use of the most effective controls that can be integrated with other tools to manage M. sacchari.
