  •  To provide information related to the host plants of the bug A. tripterus and its natural enemy Phanuropsis semiflaviventris (Hymenoptera: Scelonidae) in Panama. Methodology: The plants evaluated were located in the backyard of a home garden, where the crops of Cajanus cajan (L.) Huth and Vigna unguiculata (L.) Walp were located. (Fabaceae). 68 plants were monitored, 43 of C. cajan, in flowering, with green and dry guabas; and 25 of V. unguiculata under the same conditions of stages of plant development; where the biological interaction of A. tripterus and its parasitoid P. semiflaviventris was observed. 60 litters were collected, corresponding to approximately 1,740 eggs of A. tripterus. 35 litters of A. tripterus associated with the culture of C. cajan and 25 litters of A. tripterus associated with the culture of V. unguiculata were collected. This biological material was transported to the G. B. Fairchild Invertebrate Museum of the University of Panama for processing and further observation of A. tripterus eggs. The litters were kept in insect hatching cages in order to keep the leaves where the female "bug" were maintained, maintaining their maternal care of the eggs, in adequate conditions for the eggs to complete their development. Anova analyses, multiple Tukey comparison tests, correlation between the hatching of parasitoids and stink bugs were performed; Also, regressions were carried out between the host plants and the sampling period; Scatter plots were made to establish the interspecific relationships between nymphs (bug)-parasitoids (wasps), nymph-unhatched eggs and nymph-eggs by litters. Also, an analysis was carried out between the hatching relationship and the sampling time period.
