Mites, nematodes and the multimillion dollar weevil

Potential of Ascidae, Blattisociidae and Melicharidae (Acari: Mesostigmata) as Biological Control Agents of Pest Organisms

“…Nematode predation was also reported by Hirschmann and Rühm ( 1953 ) for Proctolaelaps fi seri Samsinak (cited as Lasioseius hystrix ) and by Krantz and Poinar ( 2004 ) for an undescribed Proctolaelaps species. The former was reported from galleries of an unidentifi ed Ips sp., and the second, on the curculionid Elaeidobius kamerunicus (Faust), onto which it was reported to attack the bacteriophagous nematode Cylindrocorpus sp.…”

“…Treat ( 1969Treat ( , 1975 reviewed data about phoresis of Proctolaelaps on moths, and on species that despite not been found phoreticly on moths, were found to feed on lepidopteran eggs and larvae. According to Halliday et al ( 1998 ), Proctolaelaps lobatus De Leon has been reported in association with many lepidopteran species, while according to Krantz and Poinar ( 2004 ), an undescribed Proctolaelaps species was found to disperse phoretically on the curculionid E. kamerunicus . Karg ( 1988 ) referred to several previous records of association of Proctolaelaps species with different species of bark beetles.…”

Mites coexistent with neotropical hispine beetles in unfurled leaves ofHeliconia: a new genus and family of the Ascoidea (Acari: Mesostigmata: Gamasina)

“…Like Antennocheles and perhaps other of the mite associates, the nematodes in furled Heliconia leaves may possibly become subelytral phoretics on the hispine beetle hosts, as they become obliged to seek moister substrates when the leaves unfurl and dry out. This may be similar to the situation observed in senescing African oil palm flowers, where both the ascoid mite, Proctolaelaps sp., and its nematode prey, Cylindrocarpus sp., become phoretic on emerging, departing adult oil palm weevils (Krantz and Poinar 2004).…”

3.7. Curculionidae Latreille, 1802

“…Weevil pollination of palms has been reported or indicated for the genera Acanthococos, Acrocomia, Astrocaryum, Attalea, Bactris, Butia, Catoblastus, Chamaerops, Cocos, Cryosophila, Elaeis, Hydriastele, Phoenix, Phytele phas, Rhapidophyllum, Rhapis, Sabal, Salacca, Serenoa, Socratea, Syagrus and Wettinia (Henderson 1986;Silberbauer-Gottsberger 1990;Meekijjaroenroj & Anstett 2003) and, given the close association of Derelomini with several other palm genera (Franz & Velente 2005), is probably more widespread in the family. The best-known case of weevil pollination of palms is that of the African Oil Palm, Elaeis guineensis, which is pollinated by the derelomine Elaeidobius kamerunicus (Faust), which was introduced to Asia in 1981 to improve seed set in oil palms planted there (Krantz & Poinar 2004).
