“…Rates determined by Berndt et al for Gaeolaelaps aculeifer Canestrini and by Castilho et al for Protogamasellopsis zaheri Abo‐Schnaf, Castilho & Moraes (cited as P. posnaniensis Wisniewski & Hirschmann, according to Castilho et al ), respectively 3.5 and 4.3 thrips per day, were similar to those determined in this study. Only recently has the net predation rate ( C o ) been reported in works concerning predation by mites . This new index provides an interesting new insight, as it integrates predation by both sexes and throughout their life cycle, in which predation is evaluated separately for each developmental stage ( e.g .…”

BACKGROUND: Parasitus bituberosus is common in rose fields and nearby vegetation around Bogotá. In rearing units, it is often aggregated, feeding on Frankliniella occidentalis edaphic phases. Preliminary observations suggested predator immatures can not reach adulthood if isolated. The objectives were to evaluate the suitability of F. occidentalis as prey for P. bituberosus, to evaluate free-living nematodes as complementary food, and to confirm the aggregation effect on predator biology. Aggregation types: (1) isolated mites, (2) mites paired only as deutonymphs and early adulthood, and (3) mites always paired. Diets: thrips (T), nematodes (N) and thrips + nematodes (NT). RESULTS: Parasitus bituberosus juveniles did not feed on live F. occidentalis, but developed and oviposited on nematodes.Approximately 77% of the isolated mites died as immatures. Mortality was low (21-23%) when predators were paired at least in the deutonymph and the early adult phase. Female daily predation rates were comparable to other predators on F. occidentalis (≥2.5). Continuously paired mites had high biotic potential, especially when the diet included nematodes (r m ≥ 0.33; R o ≥ 33.90; daily oviposition rate ≥ 10.9). CONCLUSION:The results of this study warrant further investigation of this predator, to evaluate methods for its mass production, inclusion in conservation biocontrol programs and performance against the pest at a larger scale.

“…The number of first instar nymph TPP consumed by A. limonicus immature, males, and pairs, as well as the number of eggs laid by female A. limonicus , was recorded daily until the death of the mite. To calculate the female daily predation rate of A. limonicus from the pairs, the average male daily predation rate was subtracted from the daily predation rate of the pairs . If the male died first, the total daily predation rate of the pairs was attributed to the female.…”

BACKGROUND: Predator-prey interactions consist of direct consumption of prey by predators and indirect non-consumptive effects on prey. Predator cues can induce predation stress in prey that negatively influences the survival, development, reproduction, and feeding behaviour of the prey. This study evaluated the effects of hemipteran-tending ant (Technomyrmex albipes) odour on the development, survival, reproduction, and predation rates of the predatory mite Amblydromalus limonicus when feeding on an invasive pest of solanaceous crops, Bactericera cockerelli. The age-stage, two-sex life table theory was used to compare the demographic characteristics and predation rates of A. limonicus in the presence and absence of ant odour. RESULTS:We show that exposure to ant odour did not alter the development, survival rate, and fecundity of A. limonicus, but induced a sexually dimorphic response in its longevity; consumption rates also showed that dimorphic response-predation rates increased in female A. limonicus, but not in males. CONCLUSION: To our knowledge, this is the first report indicating increased consumption rates by natural enemies exposed to odour from a mutualist of pest (ant). This finding may provide new insights into understanding tri-partite interaction involving a pest, its predator, and a mutulist of the pest.

“…persimilis , all lineages were subjected to food stress, i.e. held under limited prey conditions over 40 days, allowing about four generations (generation time [T] is ~10 to 11 d at 25°C) [36,37]. Under stressful conditions, in the short to medium term, recessive alleles are commonly more detrimental, and increase inbreeding depression effects, compared to benign conditions [26,38,39].…”

Founder effects on trans-generational dynamics of closed inbreeding lineages of the predatory mite Phytoseiulus persimilis

Both close inbreeding and distant outbreeding may reduce fitness below the level of individuals with intermediate parental relatedness. In the haplodiploid plant-inhabiting predatory mite Phytoseiulus persimilis , which is patchily distributed within and among host plants, fitness is indeed reduced in the short term, i.e. by a single generation of inbreeding. However, in the medium to long term (multiple generations), distant out-breeding should provide for favorable demographic founder effects in isolated populations. We tested this prediction in isolated experimental lineages founded by females mated to a sibling (close inbreeding), a male from the same population (intermediate relatedness) or a male from another population (distant outbreeding) and monitored lineage growth and persistence over four generations. Cross-generationally, lineages founded by distantly outbred females performed the best, i.e. produced the most descendants. However, this was solely due to superior performance from the F 2 generation onwards, whereas in the F 1 generation, lineages founded by females mated to males from their own population (intermediate relatedness) performed the best, as predicted from short-term in- and out-breeding depression effects. At the genetic level, this result was most likely due to distantly outbred founders introducing higher allelic variability and lower homozygosity levels, counterbalancing inbreeding depression, which inevitably occurs in isolated lineages, from the F 2 generation onwards.
