Author Affiliations +
Abstract

A new species, Encarsia citricola sp. n., reared from Trialeurodes floridensis (Quaintance) collected in the State of Guanajuato, Mexico, is described and illustrated. A review and a key to 9 parasitoid species attacking T. floridensis are provided. In addition, 4 species of chalcidoid wasps are recorded for the first time as parasitoids of T. floridensis in the New World.

The family Aleyrodidae (Hemiptera) is comprised of approximately 1450 described species in the world. Whiteflies are detrimental pests attacking a wide variety of agricultural crops and ornamental plants, predominantly in the tropics and subtropics (Martin et al. 2000). About 50 whitefly species are commonly found infesting economic plants around the world, and 33 species in 20 genera are considered common and economically important in the Southeastern United States (Martin 1987; Hodges & Evans 2005). Nguyen et al. (1993) listed 73 species in 20 genera, including 7 species in the genus Trialeurodes (Cockerell) in their catalog of the Aleyrodidae species associated with citrus worldwide. Carapia et al. (2003) reported 13 species in the genus Trialeurodes from Mexico, of which 6 occur on citrus.

Trialeurodes floridensis (Quaintance 1900), the guava whitefly or the avocado whitefly, is a polyphagous insect feeding on many plant species from 20 families, and is widely distributed in the New World from United States of America (Florida, Texas, Arizona) to Venezuela (Mound & Halsey 1978). In Mexico, the current known distribution for T. floridensis is from the State of Nuevo León (Russell 1963).

Five species of chalcidoid wasps in the genus Encarsia Foerster (Aphelinidae) are known at present to attack T. floridensis: Encarsia hispida De Santis, E. meritoria Gahan, E. nigricephala Dozier, E. pergandiella Howard and E. telemachusi Evans (Evans & Serra 2002; Noyes 2006).

This paper presents the list of 9 species of parasitoids attacking T. floridensis: 7 species of Encarsia, including 1 new species of Encarsia (Aphelinidae), 1 species of Metaphycus (Encyrtidae), and 1 species of Signiphora (Signiphoridae). A key for identification of these parasitoid species, information on their distribution and alternative hosts, and new records of specimens collected in Mexico are provided.

Materials and Methods

A large series of whitefly Trialeurodes floridensis pupae were collected on leaves of Citrus sinensis (L.) in San Miguel de Allende, Guanajuato, Mexico, during Nov 13-16, 2005. In the laboratory, leaves with colonies of whitefly pupae were maintained in plastic containers for parasitoid rearing. Female and male specimens from some of the emerged adult wasps were mounted in Canada balsam for morphological study and identification, following the slide-mounting method for Chalcidoidea described by Noyes (1982). A key for the identification of these species is provided, based on characters observed on specimens mounted on microscopic slides.

The whitefly species from which the parasitoids emerged were identified with keys to the puparium (=pupal cases) by Hamon (2002), Martin (1987), and Hodges & Evans (2005). Parasitoid species were identified with the pictorial guide to the species of Encarsia parasitic on whiteflies in North America (Schauff et al. 1996), the guide to Encarsia parasitoids of Bemisia tabaci (Polaszek et al. 1992), the key to Encyrtidae of Costa Rica (Noyes 2004), and the key to Metaphycus species parasitizing whiteflies (Myartseva 2006). Some specimens used in this study are deposited in the Entomological Museum of the University of Tamaulipas, UAM Agronomía y Ciencias, at Ciudad Victoria, Tamaulipas, Mexico. Morphological terminology used for the chalcidoid wasps follows that of Hayat (1998) and Schauff et al. (1996). Taxonomic information, hosts, geographic distribution, collected material, and references (only information for Mexico) are provided for each parasitoid species.

Results and Discussion

Eight parasitoid species of T. floridensis were collected in different Mexican States, including 6 species of the genus Encarsia, 1 species of Metaphycus, and 1 species of Signiphora. Moreover, Encarsia telemachusi Evans is recorded as a parasitoid of T. floridensis in Haiti. A new species, Encarsia citricola, is described and illustrated and a review and key to 9 parasitoid species attacking T. floridensis are given.

2. Encarsia hispida De Santis 1948

Synonym: Encarsia brasiliensis (Hempel 1904); synonymy according to Polaszek et al. 2004.

References: De Santis (1979); Hernández-Suárez et al. (2003); Myartseva & Ruíz Cancino (2000); Myartseva et al. (2000, 2006); Noyes (2002, 2006); Polaszek et al. (1992, 2004); Schmidt et al. (2001).

In Mexico this species was reared from Bemisia tabaci-complex, Tetraleurodes sp., and Trialeurodes variabilis.

World distribution: Nearctic USA, Mexico), Neotropical (widespread), Palaearctic (Europe), Afrotropical (South Africa), Oriental, Australasian (Australia).

Mexican Distribution: Guerrero, Sinaloa, Tabasco, Tamaulipas, Yucatan.

Material: Mexico, Tamaulipas, Ciudad Victoria, ex Bemisia tabaci-complex on Euphorbia sp., 2 females, 29-VII-1998, 1 female, 20-VII-1998, 1 female, 19-X-1998, sweeping,1 female, 11-XI-1998; Gómez Farías, El Nacimiento, ex Tetraleurodes sp. on Bauhinia divaricata, 1 female, 3-II-1999 (S. Myartseva).

Comments. Encarsia hispida was considered as a junior synonym of E. meritoria Gahan 1927 (Viggiani 1989; Schauff et al. 1996). According to Polaszek et al. (1992), they are distinct species, and molecular evidence (Babcock et al. 2001) supports this view.

In Mexico this species was reared from the Bemisia tabaci-complex, Trialeurodes vaporariorum, Tetraleurodes sp. and T. mori.

World distribution: Nearctic (USA, Mexico), Neotropical (Central and South America), Palaearctic (Europe), Australasian (Australia).

Mexican distribution: Colima, Mexico D.F., Quintana Roo, Sinaloa, Sonora, Tamaulipas. Material. Mexico, Tamaulipas, Ciudad Victoria, ex Bemisia tabaci-complex on Puansetia sp., 2 females, 9.IX.1998; ex Trialeurodes vaporariorum, 6 females, 25.I-6.II.2006; Jaumave, ex Trialeurodes vaporariorum on Malva sp., 10 females, 4 males; Tampico, ex Tetraleurodes mori, 1 male, 27.III.2001 (S. Myartseva).

Comments. Encarsia pergandiella is a Nearctic species. It was introduced into Israel and Europe to control Bemisia tabaci (Evans & Castillo 1998; Hernández-Suárez et al. 2003). Information about introduction of E. pergandiella into Mexico against Aleurocanthus woglumi Ashby (Alvarado-Mejía & González-Hernández, 1990, with reference to Dominguez & Carrillo, 1976) is erroneous.

6. Encarsia telemachusi Evans, 2002

E. telemachusi was reared from Trialeurodes floridensis in Haiti on Bauhinia divaricata (Evans & Serra 2002).

7. Encarsia variegata Howard, 1908

Hosts: Aleurodicus perseae [=Paraleyrodes perseae], Aleurothrixus floccosus, Paraleyrodes naranjae, P. perseae, Trialeurodes floridensis.

In Mexicothis species was reared from Trialeurodes floridensis.

World distribution: Nearctic (USA, Mexico), Neotropical (Colombia, Haiti, Honduras, Puerto Rico).

Mexican distribution: Chapas, Guanajuato, Nuevo León, San Luis Potosí, Tamaulipas. Material: Mexico, Nuevo León, 20 km S Monterrey, 2 females, 7.VI.2005 (S. Myartseva & E. Ruíz Cancino); San Luis Potosí, Tamuín, 1 female, 30.I.2005 (S. Varela Fuentes); Tamaulipas, Guémez, 18 females, 4 males, 10.V.2005 (S. Myartseva). All specimens were reared from Paraleyrodes spp. on Citrus spp. Guanajuato, San Miguel de Allende, ex Trialeurodes floridensis on Citrus sinensis, 2 females, 2 males, 16.XI.2005; Chiapas, Tapachula, ex Aleyrodidae on Psidium guajava, 2 females, 8-9.X.2006 (S. Myartseva).

Comments. The Universal Chalcidoidea Database (Noyes 2006) does not record Encarsia variegata as occurring in Mexico. Schauff et al. (1996) indicated that this species is presented in Mexico, but did not mention any specific localities. We reared E. variegata from Paraleyrodes spp. collected in 3 states of Mexico--Nuevo León, San Luis Potosí and Tamaulipas (Myartseva & Varela Fuentes in press) and from the states of Guanajuato and Chiapas. Trialeurodes floridensis represents a new host for Encarsia variegata.
