The effect of intrinsic competition between the exotic parasitoid Diachasmimorpha longicaudata (Ashmead) and the native species Doryctobracon crawfordi (Viereck), Utetes anastrephae (Viereck) and Opius hirtus (Fischer) (all Braconidae: Opiinae) was studied under laboratory conditions. Each native species and D. longicaudata acted as both a resident and an invader, and all species were introduced to the host simultaneously. Diachasmimorpha longicaudata was found to be the most competitive species because it achieved the highest parasitism percentage under all the experimental conditions, but it was also negatively affected by the presence and parasitic activity of the native parasitoids. Utetes anastrephae was the only species that maintained its parasitic rate when all species attacked the available hosts simultaneously. The emergence probability of a female D. longicaudata was positively associated with the increase in the number of scars on the cuticle of the host pupa, but this association was not observed for the native species. It was concluded that D. longicaudata is an intrinsic competitor that is superior to D. crawfordi, U. anastrephae and O. hirtus, whether acting as a resident or an invader, producing a female-biased sex ratio in all the evaluation conditions. Utetes anastrephae was the native species that was least affected by the competitive presence of D. longicaudata, which suggests that it could be used as a complementary biological control agent for Anastrepha fruit flies.

Resumen en inglés

We evaluated under semi-field conditions the intrinsic competition between Diachasmimorpha longicaudata (Ashmead), as an invasive parasitoid, and Doryctobracon areolatus (Szépligeti) and Utetes anastrephae (Viereck) (all Hymenoptera: Braconidae) as resident parasitoids, as well as that between U. anastrephae as an invader and D. areolatus as a resident. The percentage of live D. areolatus larvae decreased by 39.8% and 29.4% following attack by D. longicaudata and U. anastrephae as invasive parasitoids, respectively. Likewise, the parasitism percentage of D. areolatus decreased by 31.5% and 60.8% under competition with the invasive parasitoids D. longicaudata and U. anastrephae, respectively. Parasitism by D. longicaudata decreased by 44.6% and 41.6% in the presence of the residents D. areolatus and U. anastrephae, respectively, while parasitism of U. anastrephae was only affected when this species was a resident. We concluded that D. areolatus is an inferior intrinsic competitor and that U. anastrephae resists the competitive presence of D. longicaudata.

Marine protected areas (MPAs) conserve diversity and abundance of fish communities. According to the biotic resistance hypothesis, communities with higher diversity and abundance should resist invasions better. To test this idea, the presence of lionfish in two Caribbean MPAs was studied: Parque Nacional Guanahacabibes (PNG) in Cuba and Parque Nacional Arrecifes de Xcalak (PNAX) in Mexico. Selection of these MPAs was based on both their different levels of success with enforcement and different abundances of native fish, with a more abundant native fish fauna at PNG. Underwater visual censuses were used to evaluate both the native fish structure and composition and at the same time distribution and abundance of lionfish. The abundance of potential predators on lionfish was also measured to determine possible effects of lionfish on both the abundance and the size of its prey and competitors. Lionfish showed higher abundance and larger size in PNG compared to PNAX, even though its probable competitors and predators were also more abundant and larger in PNG. Prey abundance and size decreased after the invasion. No correlation was detected between potential predators and lionfish, which might indicate natural predation is not substantial. In PNAX, lower abundance of prey, potential competitors and predators can also be attributed to historical overfishing, but this did not provide an advantage to lionfish. Lionfish were less abundant and reached smaller sizes in PNAX compared to PNG. This work confirms the effectiveness of lionfish culling at PNAX, but does not support the biotic resistence hypothesis that native fish might have controlled this invasive species.

Agricultural pests represent a limiting factor for safety food production. Environmental friendly alternatives to the use of synthetic pesticides are required. Here we evaluated the effect of a novel insecticide and a new designed bait station using Anastrepha ludens sterile flies in release– recapture tests in mango orchards. Seven treatments were distributed in 35 plots of one hectare each in a five blocks arrangement. Spinosad (GF-120), malathion and abamectin, Fly-catch bait station (FC): baited with 95% water, 4% hydrolyzed protein (Captor 300) and 1% malathion, 1.5 L plastic bottle bait station (PB) baited with 250 mL of CeraTrap, Papaya Leaf Mimic station: Sprayed with GF- 120, untreated plots (control) were used as treatments. Half of the trees of each plot received the treatment. Approximately 5000 flies per plot were released at 15-day intervals, in four consecutive replicates. For monitoring, two Multilure traps/plot baited with BioLure were revised weekly. Wild populations of A. serpentina and A. obliqua were censored. Abamectin sprays and the FC induced the highest reduction in A. ludens captures (up to 50% with respect to the untreated plots). No clear effects were observed in the wild populations, since more flies were captured in some treatments than in the untreated plots, but here the initial population density and distribution was unknown. Traps in the FC treatment captured less nontarget insects than other treatments. Overall, the results indicate that the abamectin and the attract-and-kill bait stations, especially the FC, can be useful alternatives for the control of Anastrepha flies.

Resumen en español

La presente investigación tuvo como objetivo determinar si el control biológico por aumento genera competencia interespecífica con parasitoides nativos residentes en las áreas de liberación y su impacto. Se plantearon dos objetivos particulares: 1) determinar el efecto de atributos intrínsecos en las interacciones entre cuatro especies de parasitoides nativos y Diachasmimorpha longicaudata, y 2) determinar el efecto de las liberaciones aumentativas de D. longicaudata sobre el parasitismo natural. Para el primer objetivo se presentan cuatro capítulos: I) competencia intrínseca entre D. longicaudata y tres especies de parasitoides nativos en laboratorio; II) comparación de la morfología de larvas de primer instar de cuatro especies de parasitoides nativos y D. longicaudata; III) determinación de la capacidad de Doryctobracon areolatus para parasitar huevos y larvas recién eclosionadas de Anastrepha obliqua; y IV) competencia intrínseca entre D. longicaudata como invasor y dos especies nativas como residentes en frutos infestados expuestos en jaulas de campo. Los resultados demostraron que la morfología de la larva de Utetes anastrephae compensa la competencia con D. longicaudata, y que la especie Doryctobracon areolatus tiene la capacidad de parasitar embriones en el interior de huevos y larvas recién eclosionadas de A. obliqua, lo cual puede representar una ventaja al competir con D. longicaudata. Se confirmó que las especies nativas cuando son residentes defienden su recurso satisfactoriamente contra D. longicaudata. Para el segundo objetivo particular se determinó del efecto de las liberaciones por aumento de D. longicaudata sobre Anastrepha spp. y sobre el parasitismo natural (capítulo V), cuyo resultado permitió comprobar que las liberaciones por aumento de D. longicaudata complementan el parasitismo natural y reducen de manera significativa la infestación de frutos por A. obliqua.

Resumen en inglés

The Indo-Pacific lionfish Pterois volitans is an invasive species that was first recorded in the Guanahacabibes National Park (GNP), a marine protected area in western Cuba, in 2009. In order to determine the invasion progression of this species, we studied lionfish abundance, size, and diet at 6 sites in the GNP between 2010 and 2014. The species’ density, biomass, and length increased over this period, probably due to the abundance of food and shelter in the GNP. Analysis of stomach contents indicated that lionfish fed primarily on fish and crustaceans; main prey were teleosts, predominantly Gobiidae, Pomacentridae, Mullidae, Labridae, Scaridae, and Grammatidae. This example of a rapid increase in an unmanaged population at the onset of invasion provides information that can be used to design a management program targeting lionfish.

Resumen en inglés

The morphology of the first instars of the Opiinae braconids Diachasmimorpha longicaudata, Doryctobracon areolatus, Doryctobracon crawfordi, Utetes anastrephae and Opius hirtus (the first is exotic, and the others are natives to Mexico), parasitoids of Anastrepha fruit flies, are described and compared. The possible implications on interspecific competition among these species are discussed. The most significant adaptations found were: (1) the mouth apparatus, where the large mandibles and fang-shaped maxillary lobes present in D. longicaudata and U. anastrephae larvae were absent in O. hirtus, D. areolatus and D. crawfordi larvae, and (2) the degree of mobility for exploration and escape, such as the lateral and caudal appendages that were only present in D. longicaudata (ventrolateral appendages in the base of the head capsule), U. anastrephae (caudal lobe with two appendages) and D. areolatus (caudal lobe with a round apex with a globular shape). The first instar larvae of the species D. longicaudata show morphological adaptations that apparently confer competitive advantages against the larvae of D. areolatus, D. crawfordi and O. hirtus. However, the first instar larvae of U. anastrephae show larger mandibles, an adaptation that could enable this species to resist competition from D. longicaudata.

Resumen en inglés

To determine the natural parasitism in fruit fly populations in disturbed areas adjacent to commercial mango orchards in the states of Chiapas and Veracruz, Mexico, we recorded over one year the fruit fly–host associations, fly infestation, and parasitism rates in backyard orchards and patches of native vegetation. We also investigated the relationship between fruit size, level of larval infestation, and percent of parasitism, and attempted to determine the presence of superparasitism. The most recurrent species in trap catches was Anastrepha obliqua (Macquart), followed by Anastrepha ludens (Loew), in both study zones. The fruit infestation rates were higher in Chiapas than in Veracruz, with A. obliqua again being the most conspicuous species emerging from collected fruits. The diversity of parasitoids species attacking fruit fly larvae was greater in Chiapas, with a predominance of Doryctobracon areolatus (Sze´ pligeti) in both sites, although the exotic Diachasmimorpha longicaudata (Ashmead) was well established in Chiapas. Fruit size was positively correlated with the number of larvae per fruit, but this relationship was not observed in the level of parasitism. The number of oviposition scars was not related to the number of immature parasitoids inside the pupa of D. areolatus emerging from plum fruits. Mass releases of Di. longicaudata seem not to affect the presence or prevalence of the native species. Our findings open new research scenarios on the role and impact of native parasitoid species attacking Anastrepha flies that can contribute to the development of sound strategies for using these species in projects for augmentative biological control.
