Development and reproductive capacity of the predatory mite <Emphasis Type="Italic">Parasitus consanguineus</Emphasis> (Acari: Parasitidae) reared on the larval stages of <Emphasis Type="Italic">Megaselia halterata</Emphasis> and <Emphasis Type="Italic">Lycoriella ingenua</Emphasis>

Development and reproduction of the predatory mite Parasitus consanguineus Oudemans et Voigts (Acari: Parasitidae) reared on a diet of first and second instars of Megaselia halterata (Diptera: Phoridae) or Lycoriella ingenua (Diptera: Sciaridae) were studied. Mites were allowed to feed on these diets until death. The developmental time of immature stages of P. consanguineus was significantly longer when reared on L. ingenua than on M. halterata larvae (8.3 vs. 7.9 days, respectively). Survival to adulthood of P. consanguineus reared on L. ingenua or M. halterata larvae was 63 and 49%, and mite fecundity was 17.8 and 12.3 eggs/female, respectively. Adult females reared on L. ingenua lived on average 6.9 days, whereas those reared on M. halterata lived for 5.7 days. Mite survival, female longevity and fecundity were significantly different among the two diet types.

Candidate natural enemies for control of Rhizoglyphus robini Claparède (Acari: Astigmata) in lily bulbs: exploration in the field and pre-selection in the laboratory

To find suitable candidates for biological control of the bulb mite, Rhizoglyphus robini Claparède (Acari: Astigmata) on lilies, exploration was undertaken in areas where the bulb mite is an established pest (The Netherlands, Taiwan and Japan). Among the predators, found in association with R. robini in the field and under storage conditions, mesostigmatic mites predominate. The most abundant species were Hypoaspis aculeifer (Canestrini), Lasioseius bispinosus Evans and Parasitus fimetorum (Berlese). These predators appeared to feed and reproduce on a diet of exclusively R. robini and they were able to control the bulb mite in small-scale population experiments initiated with a 1:20 predator-prey ratio. Under laboratory conditions corresponding to lily bulb propagation (lily scales mixed with vermiculite and stored at 23°C and >90% RH) the laelapid mite, H. aculeifer, was the most effective predator; the ascid predator, L. bispinosus, was much less effective, but being relatively small and being successful in attacking the juvenile stages of the bulb mite it may be better able to search for bulb mites hidden inside the lily bulb. The parasitid predator, P. fimetorum, failed to control the bulb mite when vermiculite was used as a medium, but turned out to suppress this prey when peat was used instead. Various strains of H. aculeifer or closely related species were compared with respect to their impact and performance on bulb mites as prey: two Dutch strains, one obtained from Breezand and the other from 'tZand, a Taiwanese strain, a German strain that in contrast to the previously mentioned strains was not collected from lily bulbs, but from agricultural areas near Bremen and, in addition, a Canadian strain of a related species (Hypoaspis miles Berlese), known to control sciarid fly larvae. These comparative experiments showed that H. miles died out without noticeable impact on the bulb mite population whereas all strains of H. aculeifer were able to suppress the bulb mites to very low numbers. However, the numerical responses of the H. aculeifer strains differed in that those collected in association with the pest (Breezand > Taiwan > 'tZand) were superior to the strain from Bremen. These results do not provide support to the Hokkanen and Pimentel hypothesis, which states that predators forming an evolutionary new association with the pest are often more effective in biological control.
