Range Extension and Recurrent Phoresy in Paratelenomus anu (Hymenoptera: Scelionidae)
View through CrossRef
This study reports the first record of the egg parasitoid, Paratelenomus anu Rajmohana, Sachin & Talamus, 2019 (Hymenoptera: Scelionidae) from Bihar, India, and documents a novel tritrophic association involving Cajanus cajan (L.) (Fabaceae), Megacopta cribaria (Fabricius) (Hemiptera: Plataspidae), and P. anu. The recurrence of phoresy across geographically distinct populations confirms that this behavior represents a stable and adaptive host location strategy in the species. These findings highlight the potential ecological importance of P. anu as a natural biological regulator of M. cribaria in pulse-based agroecosystems, contributing valuable insights into its distribution, behavior, and prospective role in integrated pest management.
