Phytoseiid mites of Martinique, with redescription of four species and new records (Acari: Mesostigmata)

Abstract

Authors report results of a study performed between May 2011 and September 2013 on cover plants tested for future uses in citrus orchards in Martinique. A total of twenty-two species were found among which eight are very common in the West Indies. A catalogue of four new records for Martinique and three new records for the French West Indies is provided, with some information on their biology when available, and biogeography. Some considerations for six additional species, two rarely recorded in the West Indies and four already recorded and very common but with some new data and discussions, are also provided. Among these 13 species, four are re-described.

Morphological ontogeny and molecular analyses of geographic strains of two closely related Neoseiulus species (Acari: Phytoseiidae)

“…The measurements of N. longispinosus adult females in the examined strains are relatively similar to those published in the previous works (Table 2); however, the length of seta S5 of the Korean specimens reported by Lee and Ryu (1989) (33.3-51.0µm) is questionable because it is noticeably longer than normal setal range. High similarity in S5 measurements was also observed between the three strains of N. longispinosus examined in the present study (20-26µm) and those previously described from Taiwan (17µm; Tseng 1983), India (18µm; Gupta 1986) and Thailand (18-25µm; Oliveira et al 2012); however, the length of S5 is little shorter in the specimens described from Martinique (13-15µm; Kreiter et al 2018), China (16.2µm; Xin et al 1981) and the Dominican Republic (12, 15µm; Abo-Shnaf et al 2016). Regarding N. womersleyi, the measurements of adult females collected in the present study were compared with those of previous studies (Table 4).…”

Phytoseiid mites of Rodrigues Island (Acari: Mesostigmata)

“…This species is known from all Islands of French West Indies (Kreiter and Moraes 1997;Moraes et al 2000;Kreiter et al 2006Kreiter et al , 2018cMailloux et al 2010), but it was found only in very large numbers during a previous study on companion plants in Guadeloupe (Mailloux et al 2010) and in a study on La Réunion (Le Bellec, unpub. data).…”

“…This species is distributed in many countries of the world, mainly in tropical areas (Moraes et al 2000;Mailloux et al 2010;Kreiter et al 2013Kreiter et al , 2018Demite et al 2020). It was found in low numbers in Guadeloupe, Martinique and La Réunion except for studies on companion plants in citrus orchards (Mailloux et al 2010;Kreiter et al 2013Kreiter et al , 2018cLe Bellec et al, unpub. data).…”

Phytoseiid mites (Acari: Mesostigmata) of Anjouan Island (Comoros Archipelago)

“…This species have never been recorded from Guadeloupe or Martinique in similar studies, but it is interesting to notice that in those islands, another Typhlodromalus was collected, T. peregrinus (Muma) (Mailloux et al 2010; Kreiter et al 2013, 2018c. Typhlodromalus spinosus was recorded from La Réunion by Quilici et al (2000) and was then find in quite high numbers by Kreiter et al (2020d) and in few numbers from Mauritius Island (Kreiter and AboShnaf 2020b).…”
