First Record of Uroleucon pseudambrosiae (Olive) and Hyperomyzus pallidus Hille Ris Lambers (Hemiptera: Aphididae) from India with a Key to the Aphids Infesting Sonchus arvensis

Puntos clave

Uroleucon pseudambrosiae and Hyperomyzus pallidus were first recorded in India, specifically infesting Sonchus arvensis.
Both aphid species were observed feeding on the sap of S. arvensis and were documented with detailed photographic illustrations.
A key for identifying all aphid species on S. arvensis in India was included, enhancing identification efforts among researchers.
The findings expand knowledge on the distribution of aphid species in India, indicating more research is needed for local biodiversity.

Resumen

Uroleucon pseudambrosiae (Olive) and Hyperomyzus pallidus Hille Ris Lambers (Hemiptera: Aphididae) are recorded for the first time from India on Sow thistle Sonchus arvensis L.. Apterae of both these aphids were found congregating and sucking the sap from the S. arvensis L. stem and both the surfaces of leaves. A key to identify the aphid species infesting S. arvensis and photographic illustrations of live and mounted apterous viviparous females, of all nine species of aphids infesting S. arvensis L. in India, are provided.
