EP 2 612 551 B1 Printed by Jouve, 75001 PARIS (FR) EP 2 612 551 B1 Description [0001] The present invention in general relates to the field of biological crop protection by use of predatory mites. More particularly the present invention relates to a mite composition comprising a predatory mite and a prey. Such a mite 5 composition is suitable for rearing the predatory mite and/or for crop protection using the predatory mite. [0002] The use of predatory mites for biological crop protection is becoming increasingly popular in agriculture and horticulture. Currently predatory mites from the families Phytoseiidae, Laelapidae, Macrochelidae, Parasitidae, Tydeidae, Cheyletidae, Cunaxidae, Erythraeidae, Stigmaeidae are employed or have been suggested to combat pests such as phytophagous mites, thrips and whiteflies. A prerequisite for commercial use of predatory mites as biological pest control 10 agents is their availability for an acceptable price. For this the possibility to efficiently produce them in large quantities is of importance. [0003] During the past years methods for mass rearing have considerably improved in view of the availability of rearing preys (or alternatively referred to as rearing hosts) for predatory mites. Many of these newly available rearing preys are Astigmatid mites. For example reference may be made to the international applications of Koppert B.V., WO2006/057552, 15 WO2006/07110 and WO2007/075081. In addition WO2008/015393, WO2008/104807 and EP2232986 disclose addi- tional combinations of Phytoseiid predators and Astigmatid prey mite species. Such Astigmatid prey mite species have been found to be also suitable for mass-rearing of predatory species from other taxa such as predatory Mesostigmatid mite species, predatory Prostigmatid mite species. [0004] Despite these developments in the availability of rearing preys, certain limitations in the mass rearing of predatory 20 mites do remain and mass rearing would benefit from improvement of such limitations. [0005] For example the living rearing preys may also be a source of stress for the predatory mites due to their motional activity, their metabolic activity, which produces metabolic gasses and metabolic heat. These effects may in particular be very considerable at high population densities. In addition live prey individuals may produce and secrete certain chemicals, such as alarm pheromones that may be disturbing for predatory mites and may even act as a defense against 25 attacking predators. These density dependent stress factors may result in a slower population development rate and a lower maximum population density of the predatory mites due to a lower oviposition rate, a lower survival of immature and a shorter longevity of adult predatory mites. Suitable inventive solutions to eliminate or mitigate these stress factors will allow to achieve higher rearing population densities and a fast population development rate. [0006] EP 2 380 436 discloses a mite composition comprising a population of a Phytoseiid predatory species and a 30 population of an Astigmatid species and a method for rearingPhytoseiid predatory mites using the composition. The composition is characterized in that the population of the Astigmatid species is not alive. Not alive meaning that there are no live Astigmatid individuals at all (the prey is entirely inert). [0007] The composition of EP 2 380 436 and its use in rearing a Phytoseiid predator may potentially reduce or eliminate disturbing stress factors induced by live prey. However, while possibly solving certain problems, this composition also 35 has major disadvantages. The inventors of the present invention have found that dead Astigmatid mites are also a good fungal substrate and promote fungal growth. This problem is not recorded in the prior art. Extensive fungal growth negatively influences the population development rate and maximum population density of predatory mites. [0008] The present invention is based on the finding that adequate fungal reduction is required when predatory mites are reared on a population of rearing preys comprising a substantial number of dead or otherwise immobilized prey 40 individuals and that adequate fungal reduction may be obtained with a fungus reducing agent comprising a fungus reducing mite population selected from a mycophagous mite species or an antifungal exudates producing mite species. [0009] The invention therefore according to a first aspect relates to a mite composition comprising: - a population of individuals of a predatory mite species; 45 - a food source for the predatory individuals comprising individuals of at least one Astigmatid mite species, wherein at least a fraction of the Astigmatid individuals is immobilized; - optionally a food source suitable for Astigmatid individuals; - and optionally a carrier for the individuals of the mite species; 50 wherein immobilized Astigmatid individuals, and optionally the optional food source for Astigmatid individuals, are con- tacted with a fungus reducing agent comprising a fungus reducing mite population selected from a mycophagous mite species or an antifungal exudates producing mite species, said fungus reducing mite population preferably being selected from Astigmatid species. [0010] The composition comprises individuals of a population of a predatory mite. As is known to the skilled person 55 Phytoseiid predatory mites have their natural habitat on plants where they prey on pest organisms (insects and mites). They may be isolated from their natural habitats as described by de Moraes et al., 2004. Predatory mites that are particularly useful in the present invention may be selected from predatory Mesostigmatid mite species, predatory Prostig- matid mite species, in particular: 2 EP 2 612 551 B1 - Mesostigmatid mite species selected from: i) Phytoseiidae such as from: 5 - the subfamily of the Amblyseiinae, such as from the genus Amblyseius, e.g. Amblyseius andersoni, Am- blyseius aerialis, Amblyseius swirskii, Amblyseius herbicolus or Amblyseius largoensis, from the genus Euseius e.g. Euseius finlandicus, Euseius hibisci, Euseius ovalis, Euseius victoriensis, Euseius stipulatus, Euseius scutalis, Euseius tularensis, Euseius addoensis, Euseius concordis, Euseius ho or Euseius citri, from the genus Neoseiuluse.g. Neoseiulus barkeri, Neoseiulus californicus, Neoseiulus cucumeris, Neo- 10

Among the storage pests, psocids were ignored in the past due to unavailability of the significant evidence regarding quantitative and qualitative losses caused by them. Their economic importance has been recognized by many re- searchers around the globe since the last few years. The published reports suggest that the pest be recognized as a new risk for global food security and safety. Psocids have been found infesting stored grains in the USA, Australia, UK, Brazil, Indonesia, China, India and Pakistan. About sixteen species of psocids have been identified and listed as pests of stored grains. Psocids generally prefer infested kernels having some fungal growth, but are capable of excavating the soft endosperm of damaged or cracked uninfected grains. Economic losses due to their feeding are directly pro- portional to the intensity of infestation and their population. The pest has also been reported to cause health problems in humans. Keeping the economic importance of psocids in view, their phylogeny, distribution, bio-ecology, manage- ment and pest status have been reviewed in this paper.

Phytoseiid mites from South America are being evaluated as potential biological control agents of this alien pest. We evaluated six phytoseiid (Acari: Phytoseiidae) species, collected in South America: Euseius ho, Typhlodromalus aripo, Typhlodromalus tenuiscutus, Neoseiulus californicus, Neoseiulus idaeus, and Galendromus annectens. Their effectiveness as a biological control agent was estimated by measuring rates of prey con- sumption and oviposition in relation to prey density under optimal laboratory conditions. Prey consumption by E. ho, T. aripo and T. tenuiscutus continued increasing linearly up to the highest density of prey evaluated (200 prey eggs) for a maximum of 93, 101 and 59 prey in 24 h. For the other predators, prey consumption levelled off at prey density of 30 or more. Maximum daily consumption was 40, 35 and 18 eggs for N. californicus, N. idaeus and G. an- nectens, respectively. Except for T. tenuiscutus, daily fecundity appeared to reach a plateau at the prey densities tested. Higher maximum daily oviposition rates were registered for T.

  • Potential of the Blattisocius Mali (Acari: Blattisociidae) Mite As Biological Control Agent of Potato Tuber Moth (Lepidoptera: Gelechiidae) in Stored Potatoes
    Potential of the Blattisocius mali (Acari: Blattisociidae) mite as biological control agent of potato tuber moth (Lepidoptera: Gelechiidae) in stored potatoes ABSTRACT: Potato tuber moth (PTM)Phthorimaea operculella(Lep.: Gelechiidae) is one of the pest species affecting Solanaceae worldwide. It can cause up to 80% of losses in potato cultivation in fieldas well asdamage up to 100% of tubersduring storage. Blattisocius (=Typhlodromus) mali (Acari: Ascidae),a predatory mite,was studied as a potential biological control agent of PTM. An acceptance assay of PTM eggs as prey was carried out. Additionally, two assays have been conducted under microcosm conditions, which assess the densities of mite releases at two levels of PTM infestation. The results showed that B. malifemale adults accept PTM eggs as prey, and they cause a mortality rate 89.63±2.47%, 48 hours later. In addition to this, under microcosm conditions with potato tubers, we found that when the level of infestation of the pest was low, the effectiveness of the mite control varied from 72.50±28.50 to 100%, twenty-eight days later, according to the release rate of mites. Under high levels of infestation, the effectiveness of biological control of the pest varied from 53.36±25.55 to 88.85±7.17%, also according to the release rate of the mites. The possible use of biological control with B. mali of PTM, in different types of potato storages, are analysed and discussed. INTRODUCTION Pests and diseases cause pronounced losses in potato crops (Solanum tuberosum L.).Current reductions in the harvest are caused byapproximately:40.3% pathogens and viruses; 21.1% animal pests and 8.3% weeds (Oerke 2006).

  • Balaustium Mite Balaustium Medicagoense Click for Html Version
    Balaustium mite Balaustium medicagoense click for html version Summary: Balaustium mites are emerging as a significant crop pest in agricultural areas across southern Australia. They are the largest of the pest mites commonly found in broadacre crops. This species has a high natural tolerance to many insecticides and will generally survive applications aimed at other mite pests. Other strategies that are not reliant on chemicals, such as early control of summer weeds, should be considered. Occurrence: Balaustium mites are broadly distributed across the southern coastal regions of Australia. They are sporadically found in areas with a Mediterranean climate in Victoria, New South Wales, South Australia and Western Australia. They have also been found in Tasmania although their exact distribution is unclear. Balaustium mites are typically active from March to November, although mites can persist on green feed during summer if available. The known distribution of Balaustium mites in Australia (Source: cesar) Description: All mites are wingless and have four pairs of legs, no external segmentation of the abdomen and individuals appear as a single body mass. Balaustium mites grow to 2 mm in length and have a rounded red-brown body with eight red-orange legs. They are easily distinguished from other crop mites as they are much larger in size. Adults are covered with short stout hairs and are slow moving. They have distinctive pad like structures on their forelegs. Newly hatched mites are bright orange with six legs and are only 0.2 mm in length. Adult Balaustium mite (Source: cesar) Accurate identification of mite species is important because management is species specific.

Viticulture is characterized by relatively high pesticide inputs, which could decrease arthropod populations and biological pest control in vineyards. This problem could be counteracted with management practices such as the implementation of diverse vegetation cover in the vineyard inter-rows, reduced pesticide input in integrated or organic vineyards, and a di- verse landscape with trees and hedges. We examined the influence of these factors on predatory Citation: Möth, S.; Walzer, A.; Redl, mites, which play a crucial role as natural enemies for pest mites on vines, and pollen as impor- M.; Petrovi´c,B.; Hoffmann, C.; Winter, tant alternative food source for predatory mites in 32 organic and integrated Austrian vineyards.
