Definitions

  • the present invention relates to the field of insect control and more specifically to a system and method for rearing and controllably releasing biological control agents (BCA) against plant pests.
  • BCA biological control agents
  • embodiments of the present invention provide a rearing apparatus capable of both controlled and time effective rearing and releasing of the biological control agents.
  • FIG. 7A-C are schematic illustrative diagrams of optional BCA containers featuring a rearing apparatus according to embodiments of the present invention.
  • the advantage of the rearing apparatus of the present invention is that it releases the prey in stable or stationary, low and controlled amounts. This is highly important for the maintenance and viability of the micro-ecosystem comprising the apparatus, and for the reproduction and continued release of the prey from the apparatus. Contrary to the conventional thinking, release of a very large amount of prey individuals, especially in a sharp peak, is problematic for the maintenance and reproduction of the BCA population, and its' continuous release from the eco-system containing the apparatus. This is in fact, the situation in the currently available BCA release products and sachets.
  • the present invention provides a desirable solution for this problem, by providing an apparatus that is designed to limit and control the accessibility of food for the prey population and thus enable the BCA population to be released to the environment containing the plant pests over an extended period of time.
  • the term “rearing composition” as used herein, generally refers to a composition suitable for breeding, bringing up, growing, raising, upbringing, reproducing or propagating a prey mite species suitable for rearing beneficial (non-pest) insect or mite species. It is herein acknowledged that rearing systems for predatory mites or insects heavily depend on the availability of suitable prey for the predators. Therefore, there is a continuing need to improve rearing systems of both predatory mites and mites suitable as a rearing prey.
  • individuals refers in the context of the present invention to mite developmental stages including, but not limited to eggs, juvenile mite stages such as larva, protonymph and deutonymph (third instar) individuals and adult stages.
  • FIG. 2A shows a schematic non-limiting illustration of rearing apparatus 100 having at least one open end 102, 104 and an internal volume 108, ‘V”.
  • the internal volume 108 is configured to receive and house at least one rearing or growing or feeding composition 110 that features a limiting surface and/or access area 105 through open ends 102 and 104 that is configured to limit availability of the rearing composition to the prey mite individuals and thus sustain the growth of a BCA population.
  • rearing apparatus 100 comprises at least one open end 102, 104 defining a rearing composition access area and/or feeding surface 105 as shown in FIG. 2B.
  • the access area 105 enable limiting the available food source to the prey population fed on by the BCA, therein ensuring that the food supply and/or rearing composition 110 is maintained for an extended period of time that in turn, leads to a longer lasting BCA population, as will be discussed in reference to FIG. 8-10.
  • sheets 106a, 106b may be provided from optional materials for example including but not limited to the group consisting of: plastic, polymers, foil, laminates, semipermeable materials, gas permeable materials, water resistant materials, silicon, resin, lacquer, wood, composite materials, metal, hybrid materials, alloys, carbohydrates, starch, plant based materials, plant fibers, fibrous materials, mesh, the like or any combination thereof.
  • a rearing apparatus 100 may be configured to receive at least one or more rearing composition 110, for example as shown in FIG. 4A-C. In some embodiments, rearing apparatus 100 may be configured to receive at least two or more different rearing composition 110a, 110b, for example a shown in FIG. 4A-4C, within a volume 108.
  • FIG. 5E shows a similar configuration wherein a plurality of individual different sized rearing apparatuses 100 are utilized to form a single rearing apparatus 200 wherein each tube may be specific to a particular BCA or prey population.
  • FIG. 7A comprises a rearing apparatus 100 comprising an elongated body 106 that spans both the internal volume of container 50 and extend externally to container 50.
  • a body featuring an end 104e that may be adapted to be placed within the soil and/or ground of the cropping environment.
  • end 104e may be configured to be a spike type end to facilitate soil placement.
  • the present invention provides the rearing apparatus as defined in any of the above, wherein the internal surface has a uniform or alternatively, a changing/non-uniform diameter along the length.
  • the present invention provides the rearing apparatus as defined in any of the above, wherein the at least one access area has a width (diameter) of at least 2.5 mm.
  • the present invention provides the rearing apparatus as defined in any of the above, wherein the at least one access area has a width (diameter) of less than 10 mm.
  • the present invention provides the rearing apparatus as defined in any of the above, wherein the length (L) is at least 40 mm.
  • the size of the access points may be correlated to the (physical/physiological) characteristics of the prey, such as the physical size of the prey mite.
  • the present invention provides the rearing apparatus as defined in any of the above, wherein at least 5% of the volume is filled with a prey population.
  • the present invention provides the rearing apparatus as defined in any of the above, wherein the rearing apparatus is configured to allow the BCA to be released over a period of at least 6 weeks, preferably over a period of at least about 7 weeks. According to some aspects, the rearing apparatus is configured to allow said BCA to be released over a period of between 40 to 180 days, for example, about 50 to 150 days (e.g. at conditions of about 25 degrees and about 75% relative humidity).
  • the apparatus additionally comprising at least one enclosure, configured for containing a population of prey mites.
  • the enclosure is configured to prevent departure of the BCA and prey mites.
