“…Overall, in the present study, the pollens supplied with honey did not enhance the oviposition of A. largoensis and T. ornatus. Honey also did not increase the oviposition of Metaseiulus occidentalis (Nesbitt) (Yanar & Marjorie 2015). Regarding R. indica, A. largoensis is the most common natural enemy associated with this coconut pest on plantations worldwide (Rodrigues et al 2007;Carrillo et al 2012), and this mite supported the oviposition of the predator as much as both pollens supplied separately, but still the mixed pollen diet was superior.…”

Amblyseius largoensis and Typhlodromus ornatus (Acari: Phytoseiidae) are generalist predatory mites that naturally inhabit coconut plantations and other tropical crops. We assessed the suitability of two coconut pest mites, Raoiella indica (Acari: Tenuipalpidae) and Aceria guerreronis (Acari: Eriophyidae); the storage mite Tyrophagus putrescentiae (Acari: Acaridae); honey; and the pollens of castor bean, Ricinus communis, and cattail, Typha domingensis, and their mixture, as food sources for the mass rearing of A. largoensis and T. ornatus. Both pollens, supplied singly or mixed, generated the highest progeny production by both A. largoensis and T. ornatus, and were therefore selected for further life table studies. The pollen diets did not influence the survival of A. largoensis whereas there was higher survivorship of T. ornatus fed on the mixed pollen diet than on R. communis pollen alone. The maximum oviposition rate of both A. largoensis and T. ornatus occurred at the beginning of adulthood, irrespective of the pollen diet. Overall, the life table parameters indicated that the pollen of R. communis for A. largoensis, and R. communis with the mixed pollen diet for T. ornatus, were the best regarding population growth and reproduction. Collectively, our results indicate that A. largoensis and T. ornatus can survive and reproduce excellently when fed solely on R. communis or on the mixed pollen diet. In addition, these results point to the potential of pollen supplementation for the enhancement of the efficiency of these predators in conservation biological control.

Neoseiulus bicaudus Wainstein (Acari: Phytoseiidae) is a beneficial predatory mite to control spider mites. To evaluate the suitable storage conditions of N. bicaudus, the survival of adult females was observed under different combinations of low temperature (3, 6, 9, or 12°C), food (F) or no food (NF), and high (H) or low (L) humidity conditions for 7, 14, 21, 28, and 35 d. Predator mites’ longevity and survival time of 50% and 80% individuals (ST50,80) were measured and compared between treatments. After storage, female and male living mites were paired at 26°C. The progeny parameters were evaluated after storage. Results revealed that survival rate decreased as storage temperature decreased. At 3 and 6°C, fewer mites survived after 28 d. At 9°C, ~50% of the females survived in the FH treatment after 35 d. At 12°C, >80% survived 7–35 d in the FH treatment. Moreover, longevity and ST50,80 were significantly greater in the FH treatment than in the FL or NFH treatments at 3, 9, and 12°C. The highest longevity (48.6 ± 3.7 d) and ST50 (51.6 d) occurred at 12°C in the FH treatment. There was no effect on progeny hatching or survival rates when adults were stored at 9 or 12°C for 28 d. At 9°C, the total preadult development time was 4.20–5.25 d. At 12°C, the total development time was 4.87–4.93 d and there was no significant difference between the storage treatment and control group. These results demonstrated that N. bicaudus females can be successfully stored at 9°C for ~21 d and 12°C for ~28 d with little effect on adult survival or progeny parameters.

“…There has also been previous evidence of life table parameters of G. occidentalis supplying a strict daily diet of O. yothersi (10 immatures) (Rioja and Vargas, 2009). Along with that, Yanar and Hoy (2015) studied biological parameters of G. occidentalis after different intervals at low temperatures to determine the storage potential for its commercialization and use in biological control programs; their results reveal that G. occidentalis can be stored at 7 °C or 10 °C for up to 4 wk. Therefore, life table parameters of G. occidentalis on O. yothersi populations are of substantial importance to examine the maximum of its potential as a biological control agent.…”

The red mite, Oligonychus yothersi (McGregor) (Acari: Tetranychidae), is a serious pest of avocado (Persea americana Mill.) 'Hass' in Chile. Micro-coleopterans predators are observed in avocado orchards during outbreaks of O. yothersi, which are attracted by herbivore-induced plant volatiles (HIPVs). However, the damage to plants persists and new predators are needed. Due to its effectiveness and adaptability to dry climates, the western predatory mite Galendromus occidentalis (Nesbitt) (Acari: Phytoseiidae) has been adopted as a biological control agent on many crops. Ours objectives were to study the biological parameters of G. occidentalis preying on O. yothersi in controlled conditions and its attraction to volatile compounds from avocado shoots, live preys and four synthetic doses of methyl salicylate (MeSA) and ocimene using a Y-tube olfactometer. We found a net reproductive rate (R0) 34.41 offspring female -1 , intrinsic rate of increase (rm) 0.19 females female -1 d -1 , finite rate of increase (λ) 1.21 females female -1 , mean generation time (T) 18.45 d, and doubling time (DT) of 3.61 d. Immature phytoseiids took 7.32 d to reach adulthood with 90% survival. Female longevity and fecundity were 36.27 d, and 59 eggs female -1 , respectively. Phytoseiids show no attraction to O. yothersi volatiles or volatiles of O. yothersi-infested avocado shoots. Nevertheless, females showed a preference for synthetic MeSA and ocimene at 100 μg mL -1 . Our findings indicate that O. yothersi is a potential diet to rear G. occidentalis, and MeSA and ocimene could be used in lures to manipulate its behavior in avocado orchards.
