Jaliscoa

Bouček, 1993

Jaliscoa is a of in the , established by Bouček in 1993. The genus was redefined in a 2013 taxonomic revision and currently includes four : J. nudipennis ( species), J. bouceki, J. hunteri, and J. vulgaris. The most extensively studied species, J. hunteri, is a of in the genus Anthonomus, particularly the (A. eugenii), and has been investigated as a agent. Unlike many parasitoids, J. hunteri exhibits significant that contributes to pest suppression.

Identification

Jaliscoa is distinguished from related (Catolaccus, Eurydinoteloides, Lyrcus, Trimeromicrus) by morphological features detailed in the 2013 revision, including specific arrangements of , mesosoma, and metasoma characteristics. The genus can be differentiated from Catolaccus by features of the propodeum and structure. Macrophotography and scanning electron photomicrography of primary are available for -level identification. J. hunteri specifically has been noted as previously classified under Catolaccus and Pteromalus before transfer to Jaliscoa.

Habitat

Associated with agricultural and horticultural systems where occur, including pepper (Capsicum annuum) and tropical hibiscus (Hibiscus rosa-sinensis). Field collection sites include areas with ; specific natural preferences beyond host-associated locations are not documented.

Distribution

New World distribution; transferred to Jaliscoa originate from Nearctic and Neotropical regions previously assigned to Catolaccus and Pteromalus. Specific geographic range data for individual species other than collection-locality information for J. hunteri is limited.

Host Associations

Behavior

J. hunteri exhibits discrimination capacity, preferring over regardless of whether females are wild-caught or laboratory-reared. The engages in substantial on stages of hosts (, , ), functioning more as a than a strict in some contexts. Females are attracted to volatiles emitted by -infested plants and fruit. Host feeding mortality can reach high levels: up to 62% suppression of offspring in controlled conditions, with greater efficacy on L3 larvae than L1 larvae and on small versus large fruit.

Ecological Role

agent of pests in agricultural systems. Functions primarily through rather than in some associations, contributing to pest suppression in pepper and hibiscus . Potential value in commercial greenhouse production where retention rates can be high.

Human Relevance

Investigated as a agent for the (), a major pest of field and greenhouse pepper in North America. Mass rearing on (Callosobruchus maculatus) has been explored to reduce production costs, though effectiveness may be compromised compared to rearing. Also evaluated for control of the hibiscus (Anthonomus testaceosquamosus) in tropical hibiscus nurseries.
