“…The detection of only Amblyseiinae in this work is consistent with the much higher diversity of this, as compared to other phytoseiid subfamilies in tropical and subtropical areas (Chant and McMurtry 2006). Furtado et al (2006) and Fiaboe et al (2007) discussed the predominance of this group in similar surveys conducted in different parts of Brazil.…”

The mite Tetranychus evansi Baker & Pritchard (Tetranychidae) probably originated in South America. Because of its importance as a tomato pest in Africa, an extensive project has been conducted to detect potentially effective natural enemies in South America for the classical biological control of the pest in Africa. A search for the natural enemies of T. evansi was conducted in the Province of Tucumán, northwestern Argentina, in December 2004, and this report describes the results. One hundred predatory mites of the family Phytoseiidae referring to 11 species were collected on 11 examined species of solanaceous plants. The most abundant phytoseiid species collected were Neoseiulus californicus (McGregor) and Euseius concordis (Chant). Adults and immatures of those species, as well as of Neoseiulus idaeus Denmark & Muma, Phytoseiulus fragariae Denmark & Schicha and Proprioseiopsis cannaensis (Muma) were found in association with T. evansi, suggesting that they were developing on the pest. However, because of the possible biological differences between populations of a given species, biological studies evaluating T. evansi as a prey for those predators seem desirable.

“…A very high diversity of Amblyseiinae on solanaceous plants was also observed in similar studies in northeastern Brazil (Furtado et al 2005;Rosa et al 2005), but this could just reflect the higher diversity of this subfamily in tropical and subtropical regions (Chant and McMurtry 2006).…”

Tetranychus evansi Baker & Pritchard is an important pest of Solanaceae in several countries. Introduced accidentally to Africa, it presently occurs in many countries of that continent. In some of them, it is considered a key pest. The suspected area of origin of this mite is South America. The objective of the present study was to identify phytoseiid mites on solanaceous plants in association with T. evansi in south and southeast Brazil for introduction in the African continent for use in a classic biological control program. Almost 1,400 predatory mites of the family Phytoseiidae were collected, on 22 solanaceous species. The Amblyseiinae were the most diverse group in this study. Twenty-three of the species found belong to this subfamily, while only three belong to the Typhlodrominae and two to the Phytoseiinae. The most abundant and most frequent phytoseiid species were Phytoseius guianensis De Leon and Galendromus annectens (De Leon) of the Phytoseiinae and Typhlodrominae, respectively. The most frequent and abundant species of Amblyseiinae was Neoseiulus tunus (De Leon). Phytoseius guianensis and N. tunus were never found in association with T. evansi and G. annectens was found only once in association with it. Two factors suggested Phytoseiulus longipes Evans as the most promising predator found in this study. It could walk very well on tomato leaves infested by T. evansi, without being hampered by the profuse webbing produced by the prey and by the trichomes. In addition, several specimens of both sexes including eggs and nymphs of the predator were found associated with T. evansi on three different plant species and in two different periods of the year, when T. evansi was the only arthropod present on the leaves.

“…It is widespread all over the world and includes more than 90 genera and 2045 species (Chant 1993;McMurtry 2003a, 2003b;Moraes et al 2003;Ragusa 2003;McMurtry 2004a, 2004b;Moraes et al 2004;Chant and McMurtry 2005a, 2005b, 2005c2006a, 2006bKreiter and Tixier 2006). Many species are considered as major predators of phytophagous mites in various crops worldwide (Kostiainen and Hoy 1996;McMurtry and Croft 1997).…”

The extent intraspecific variation among 42 morphological characters within Neoseiulus californicus (McGregor) (Acari : Phytoseiidae) is examined. Neoseiulus californicus is an important biological control agent used commercially worldwide to control pest mites in many crops. The correct diagnosis of this species is thus of prime importance for successful biological control and agricultural development. Incorrect interpretation of intraspecific variation could lead to misidentification and potentially to the description of new species that may be invalid. Three hundred female N. californicus representing ten populations collected from all over the world were measured and compared with the types of two morphologically close species: Neoseiulus marinus (Willmann) and Neoseiulus ornatus (Athias-Henriot). Significant differences between the populations were observed for almost all of the characters considered. However, these differences were small and low within-population standard errors in measurement data were observed. The mites collected in Chile were very different from the specimens of the other populations of N. californicus considered. The level of intraspecific morphological variation found within N. californicus indicates that caution must be applied to correctly determine species boundaries within this genus and morphological variation needs to be considered more in species' descriptions. Based on our morphological analysis we conclude that N. ornatus, N. marinus and N. californicus are valid species. Redescriptions of these three species are given in this paper.
