“…Several researchers have studied (aspects of) the biology of this predator, and different results were obtained, e.g., in developmental time, fecundity, reproduction mode, and prey consumption (Zaher and Soliman 1971;Summers and Witt 1973;Rizk et al 1979;Yousef 1982;Saleh et al 1986;Nangia et al 1994;Pekar and Hubert 2008). These differences may be attributed to the occurrence of various biotypes in different regions of the world (Palyvos and Emmanouel 2004).…”

“…It is also the most common predatory mite in stored products in Greece (Palyvos and Emmanouel 2004;Palyvos et al 2008). It is known to prey on other mites, especially acarids, and also feeds on eggs of Ephestia cautella Walker, Corcyra cephalonica (Stainton) and Tribolium confusum Duv., and it attacks young larvae or nymphs of other insects (Rizk et al 1979;Yousef et al 1982;Nangia et al 1994). Cheyletus malaccensis is associated with both grain mass and grain residues (Hubert et al 2006).…”

The effect of temperature on the development of immature stages of the predator Cheyletus malaccensis Oudemans, produced by either fertilized or virgin females, was studied at 17.5, 20, 25, 30, 32.5, and 35 degrees C, 80 +/- 5% relative humidity, in complete darkness, and fed Tyrophagus putrescentiae (Schrank). The population maintained at 15 degrees C failed to reproduce. The thermal data obtained were used for the estimation of the thermal requirements (developmental thresholds, thermal constant, optimum temperature) of this predator by a linear and nonlinear model (Logan type I model). Upper and lower developmental thresholds ranged between 37.4-37.8 and 11.6-12.0 degrees C, respectively. Optimum temperature for development was estimated at between 33.1 and 33.5 degrees C. The thermal constant ranged between 238.1 and 312.5 degree-days. Based on the data of the total pre-imaginal period, immatures' survival peaked at 25 degrees C. Arrhenotokous parthenogenesis (haplodiploidy) is confirmed in the species: virgin females always produce males, whereas fertilized females give rise to offspring of both sexes. Survival of the immature stages and offspring sex ratio were not significantly influenced by temperature.

“…In fact, this species was recovered from all categories of storage facilities, being dominant in silos and inXuent in stores of agricultural cooperative unions. This species feeds not only on pest mites but also on insect eggs (Rizk et al 1979;Yousef et al 1982) and it is associated with both grain mass and grain residues (Hubert et al 2006). In the present study C. eruditus, common in central and northern Europe (Hubert et al 2006;Lukas et al 2007), was found in much lower numbers.…”

Mites associated with stored products in Greece

A faunistic survey of mites was conducted in many product stores during a 6-year study period, 2000-2005, in Greece. A total of 1,073 samples were taken from 34 Greek counties. The survey was carried out on grains (wheat, maize, oat, barley), flour, bran, manufactured agricultural foodstuffs, dried fruits (figs, raisins), residues and dust, stored in varying quantities in five types of storage facilities (stores of agricultural cooperative unions, farm stores, commercial stores, flour mills and silos). Dominance-frequency analysis and redundancy analysis (RDA) were used to reveal the preferences of the collected taxa. Approximately 55% of the samples contained mites and 65 mite taxa were identified, belonging to 15 families in four orders. Six species, namely, Acarus gracilis Hughes, A. immobilis Griffiths, Caloglyphus oudemansi (Zachvatkin), Suidasia medanensis Oudemans, Tyrophagus perniciosus Zachvatkin and Kleemania plumigera (Oudemans), were new to the fauna of Greece. Five species, Tyrophagus similis Volgin, Blattisocius mali (Oudemans), Neoseiulus barkeri (Hughes), Cheyletus cacahuamilpensis Baker and Storchia robustus (Berlese), were recorded for the first time in stored products in Greece. Lepidoglyphus destructor (Schrank), Tyrophagus putrescentiae (Schrank) and Acarus siro L. were dominant or intermediate in all storage facilities examined. Cheyletus malaccensis Oudemans was the most common predatory mite. The highest percentage of infestation (65.3) was recorded in the samples from stores of agricultural cooperative unions. Residue-type materials had the highest degrees and percentages of infestation.

Reproduction, survival, and life table parameters of the predatory mite Cheyletus malaccensis Oudemans were evaluated at six constant temperatures: 17.5, 20, 25, 30, 32.5 and 35°C, feeding on Tyrophagus putrescentiae (Schrank). Preoviposition period of fertilized and virgin females varied with temperature from ca. 9 days at 17.5°C to ca. 1.5 day at 32.5°C and then increased to ca. 3 days at 35°C. Virgin female oviposition period was significantly shorter than for fertilized females at the temperatures examined with the exception of 17.5°C. The mean total number of eggs per fertilized (169.7 ± 6.6) and virgin female (60.7 ± 4.3) was highest at the temperature of 30°C. The data indicated a significant positive and nearly doubling effect of fertilization on female fecundity at the temperatures examined with the exception of 17.5°C. Age-specific fecundity was described by a temperature dependent model from which the maximum daily fecundity rate was estimated for fertilized and virgin females at 10.3 (at 30°C) and 6.8 (at 32.5°C) eggs/female, respectively. Virgin female longevity was significantly shorter than for fertilized females at 20, 30 and 32.5°C, and decreased from ca. 57 days at 17.5°C to ca. 17 days at 35°C. The Weibull function that was used to describe the age specific survival of fertilized and virgin females produced excellent fits to the survival data. Estimates of intrinsic rate of increase, net reproductive rate, mean generation time, doubling time and finite rate of increase, were obtained. The r(m) value increased with temperature from 0.03 (day(-1)) at 17.5°C to 0.21 (day(-1)) at 32.5°C, after which it decreased to 0.15 (day(-1)) at 35°C. These data indicate that C. malaccensis can reproduce at temperatures between 17.5 and 35°C and can be used for biological control of astigmatid mites within the temperature range where the pest occurs.
