“…Also, some astigmatid mites are a source of allergens that can persist and accumulate in the environment, and may cause respiratory problems in workers (Arlian, Vyszenski-Moher, Johansson, & van Hage-Hamsten, 1997;Green & Woolcock, 1978;Johansson, Johansson, & van Hage-Hamsten, 1994). Moreover, living astigmatid mites secrete defensive oils and are mobile, which can limit successful prey capture by predatory mites, particularly young predators (Midthassel et al, 2013;Midthassel et al, 2016;Rifà & Griffiths, 2018). Supplementing the diet of predatory mites with frozen stages of astigmatid mites in crops might, therefore, be an interesting approach to increase the likelihood of retaining released predatory mites.…”

Astigmatid mites have potential as supplementary prey items to support generalist predator populations in crops. However, applying living prey mites has some disadvantages; if not predated they have the potential to cause crop damage and allergies. In this study, we evaluated various diets based on the astigmatid mite Tyrophagous putrescentiae (Schrank) as a supplemental food source for the predatory mite Amblyseius swirskii Ahias-Henriot. Eggs and larvae of T. putrescentiae were reared on a diet of dog food (rich in proteins and fat) or bran (rich in carbohydrate); they were offered either frozen or alive, and either with or without cattail pollen (Typha angustifolia L.). Oviposition rate of A. swirskii fed with frozen mite larvae reared on dog food was similar to the rate observed when they were fed with cattail pollen or living prey mites, but developmental time of A. swirskii was longer on this frozen diet than on a diet of living prey mites or pollen. Both living and frozen prey mites were, in contrast with cattail pollen, not suitable for oviposition by western flower thrips, Frankliniella occidentalis Pergande. In a greenhouse study, the use of frozen prey mite stages as supplemental food on chrysanthemum plants allowed populations of A. swirskii to establish, but not increase; in contrast, provision of living prey mites and pollen increased A. swirskii populations on plants. Hence, our study shows that living prey mites, but not frozen prey mites, had the greatest potential as a supplemental food source for A. swirskii.

“…Alarm pheromones are chemical compounds that are released during stress conditions by an individual, suffering from direct contact with disease (Carr and Roe, 2016;Midthassel et al, 2016;Li and Zhag 2018). In alarming situations, mites detect very low concentrations of alarm pheromones and make a safety net around them which is helpful to make clusters for the survival of their group.…”

Natural Control Perspectives of Dermanyssus Gallinae in Poultry

Dermanyssus gallinae (Poultry red mite) is known to be the most dangerous ectoparasite of poultry. Specifically, it causes vascular damage, loss of blood, skin rashes in the host, and sometimes leads to death. D. gallinae has animal health and welfare issues but it mainly affects eggs-production industry. Global annual loss due to D. gallinae is 3.92 billion USD. Different chemical compounds and pesticides are used to control poultry red mites in poultry farms. However, the emergence of drug resistance against different chemical compounds and harmful drug residues in meat and eggs limit chemical control. In this scenario, there is a dire need to find alternatives to chemical control. This review mainly highlights the alternates of chemical control i.e. volatile compounds, pheromones, and kairomones. Pheromones and kairomones attract D. gallinae and hamper the parasite growth. While certain volatile compounds and plant extracts exert repellent effects on D. gallinae leading to decreased or no growth. Finally, effective treatments against D. gallinae are required to control infestation in poultry. In the future, different devices that have been tested on species of the Acari genus can be used to control poultry red mites.

Factitious food for mass production of predaceous phytoseiid mites (Acari: Phytoseiidae) commonly found in Brazil

Phytoseiid mites are commonly used as biological control agents of mite and small insect pests. To facilitate the production of phytoseiids, alternative food sources have been evaluated. The aim of this study was to evaluate the suitability of different food sources for the rearing of the phytoseiids Amblyseius tamatavensis Blommers, Euseius concordis (Chant) and Neoseiulus anonymus (Chant and Baker). This study evaluated the levels of oviposition of these predators when fed with 15 Astigmatina (Sarcoptiformes) mite species, one species of a bacteriophagous nematode, and pollen from five plant species. The highest oviposition rates of A. tamatavensis were obtained when fed on the mites Thyreophagus cracentiseta Barbosa, OConnor & Moraes and Aleuroglyphus ovatus (Troupeau) (2.6 and 2.1 eggs/female/day, respectively). The five highest oviposition levels of E. concordis occurred when the food source was pollen, especially of Ricinus communis L. (1.7 eggs/female/day). The evaluated oviposition levels of N. anonymus were at most 0.5 eggs/female/day on all food sources. The construction of life tables of A. tamatavensis and E. concordis with the two most favorable food sources showed that in both cases the values of r were higher when the predator was fed with T. cracentiseta and R. communis, respectively. The possible use of pollen of Elaeis guineensis L. should be further evaluated, given the acceptance of this type of pollen by E. concordis and the ease of obtaining large amounts of this pollen in areas where this crop is grown.
