“…In this study, we provide the first record for the occurrence of this species in Canada. While it is possible that this species is adventive, having been imported along with weevil-infested peppers from Mexico or Florida (Aguilar and Servín 2000;Rodríguez-Leyva et al 2000), it may also have come into Canada from more proximal sources. For instance, J. hunteri has been previously recorded in Washtenaw County, Michigan, United States of America (Gibson 2013), which is~120 km away from the site at which the species was recorded in Canada.…”

The pepper weevil,Anthonomus eugeniiCano (Coleoptera: Curculionidae), is the most important pest of pepper (CapsicumLinnaeus; Solanaceae) crops in North America. Native to Mexico, the southern United States of America, and Central America, it is intercepted in Canada when peppers are imported to supplement domestic production. Given the proximity of greenhouse and field production to packing facilities, this pest poses a serious risk to the cultivation of peppers in Canada. Once established, it is difficult to control because immature stages of the weevil are protected within the pepper fruit. As such, chemical control targeting these life stages is not effective, and other strategies, including biological control, may prove useful. To explore the potential for biological control options to manage the pepper weevil in areas at risk in Canada, natural enemy surveys were conducted in southern Ontario following the reports of transient, localised field populations in 2016. Parasitoids belonging to three Hymenoptera families including Pteromalidae (Jaliscoa hunteriCrawford,Pteromalus anthonomiAshmead), Eupelmidae (Eupelmus pulchricepsCameron), and Braconidae (NealiolusMason species,BraconFabricius species) were reared from infested field-collected pepper fruits. Together, these new natural enemy records could facilitate the exploration and development of novel agents for the biological control of the pepper weevil.

“…The experiment was carried out with females from two origins: wild (from the field and emerged from the natural host A. eugenii); and from the laboratory, raised during 13 successive generations in the factitious host C. maculatus. Females were individually placed on an observation arena, which consisted of a Petri dish (10 x 10 x 2.5 cm) with four artificial oviposition devices (Parafilm bubbles), similar to those describe by Rodríguez- Leyva, E., et al (2000). Two of the four devices had two larvae at 3rd instar of A. eugenii (natural host), these were selected based on the characteristics described by Torres-Ruíz & Rodríguez- Leyva (2012); on the other two remaining devices, two larvae of the fictitious host susceptible to parasitism (4th instar of C. maculatus) were placed.…”

“…El experimento se realizó con hembras de dos orígenes: silvestres (provenientes de campo y emergidas del huésped natural A. eugenii); y de laboratorio, criadas por 13 generaciones sucesivas en el huésped facticio C. maculatus. Las hembras se colocaron individualmente en una arena de observación, la cual consistió en una caja Petri (10 x 10 x 2.5 cm) con cuatro dispositivos artificiales de ovoposición (burbujas de Parafilm), similares a los descritos por Rodríguez- Leyva, E., et al (2000). Dos de los cuatro dispositivos contenían dos larvas de 3er ínstar de A. eugenii (huésped natural), las cuales fueron seleccionadas con base en las características descritas por Torres-Ruíz & Rodríguez- Leyva (2012); en los otros dos dispositivos restantes se colocaron dos larvas del huésped facticio susceptibles a parasitación (4to ínstar de C. maculatus).…”

“…Among its hosts of agricultural importance, there is the pepper weevil (Anthonomus eugenii Cano). Several studies highlight that, due to its biology and behavior, this parasitoid has potential as a biological control agent of that pest (Murillo-Hernández, García-Martínez, Rodríguez-Leyva, & Lomeli-Flores, 2019;Rodríguez-Leyva, Leyva, Gómez, Bárcenas, & Elzen, 2000;Rodríguez-Leyva, Stansly, Schuster, & Bravo-Mosqueda, 2007;Schuster, 2007).…”

“…Jaliscoa hunteri (Crawford) es un ectoparasitoide solitario, sinovigénico y generalista que ataca a 17 especies de Curculionidae y dos de Bruchidae (Chesnut & Cross, 1971); entre sus huéspedes de importancia agrícola se encuentra el picudo del chile (Anthonomus eugenii Cano). Diversos estudios destacan que, por su biología y comportamiento, este parasitoide tiene potencial como agente de control biológico de esa plaga (Murillo-Hernández, García-Martínez, Rodríguez- Leyva, & Lomeli-Flores, 2019;Rodríguez-Leyva, Leyva, Gómez, Bárcenas, & Elzen, 2000;Rodríguez-Leyva, Stansly, Schuster, & Bravo-Mosqueda, 2007;Schuster, 2007).…”

La cría masiva de organismos benéficos sobre el huésped natural suele ser muy costosa. Por lo tanto, huéspedes más fáciles de cultivar se buscan para reducir los costos de producción; sin embargo, ellos pueden perder su efectividad en campo. Por consiguiente, el objetivo de este estudio fue comparar la capacidad de discriminación del parasitoide Jaliscoa hunteri (Hymenoptera: Pteromalidae) sobre su huésped natural (Anthonomus eugenii Cano) o uno facticio (Callosobruchus maculatus Fabricius). Los ensayos se realizaron en unidades de ovoposición artificiales utilizando hembras colectadas en campo y hembras obtenidas de una colonia que tenían 13 generaciones, criadas sobre un huésped facticio. La procedencia de las hembras utilizadas en la investigación no afectó la preferencia de ovoposición y la alimentación sobre el huésped; sin embargo, las hembras silvestres y de laboratorio prefirieron más al huésped natural que al facticio.

The pepper weevil Anthonomus eugenii (Cano) (Coleoptera: Curculionidae) is an economically important pest of both field and greenhouse pepper crops, Capsicum annuum Linnaeus (Solanaceae) in North America. Among its natural enemies is the parasitoid wasp Jaliscoa (= Catolaccus) hunteri (Crawford) (Hymenoptera: Pteromalidae), whose potential control of A. eugenii appears promising but is currently unclear. We conducted controlled environment trials to quantify A. eugenii offspring emergence following exposure to J. hunteri, examining how parasitoid exposure period, weevil host life stage, pepper cultivar, fruit size and abscission status affect weevil-natural enemy dynamics. In pepper cultivar comparison trials, we identified a significant reduction in weevil offspring emergence from three different cultivars of ornamental peppers infested by A. eugenii, but no difference among them. In trials comparing wasp exposure period and weevil larval instar, pepper plants of one cultivar (Blaze) were exposed to A. eugenii adults, and subsequently to J. hunteri wasps for either three or seven days, when offspring weevils were either at the L1 or L3 instar. Offspring emergence was significantly reduced up to 62% when L3 but not L1 weevils were exposed to wasps for 7 days. Following this longer exposure period, significantly greater weevil suppression occurred in small (71.7%) versus large fruit (62.5%), with an additional 15.1% weevil suppression resulting from attached relative to abscised fruit. These results highlight the potential for J. hunteri as a biological control agent of A. eugenii on pepper crops, with particular value in commercial greenhouse production where wasp retention rates can be high.
