Abstract: An apparatus may include a vessel having an interior space to receive water and insect pupae. The apparatus may include a release container connected to the vessel and a sensor positioned proximate to the release container to detect an adult insect passing by the sensor and into the release container. A shutter may be positioned proximate to an entrance to the release container. The shutter may have an open position and a closed position to control access between the vessel and the release container.

Abstract: One example insect release device includes a vessel defining a volume, the vessel has first and second surfaces substantially opposite each other, the first surface defining an opening into the volume; a population of insect larvae or pupae or adult insects within the volume; and a seal positioned to obstruct the opening and adhered to the first surface. Another example insect release device includes a vessel defining a volume; a population of insect larvae or pupae or adult insects disposed within the volume; wherein the vessel is permanently sealed, and wherein release of the insect larvae or pupae or adult insects occurs upon rupture of the vessel. A further example insect release device includes a vessel defining a volume; a population of insects disposed within the volume; and a gimbal mechanism coupled to the vessel, the gimbal configured to maintain a substantially constant orientation of the vessel.

Abstract: A sieving method for separating insect pupae is described. The method may include causing an actuation system of a sieving apparatus to cycle between a first elevation and a second elevation to cyclically submerge a sieve surface of a sieving device in a liquid held within a basin so as to separate a population of insect pupae present in the sieving device with respect to size. The method may also include causing actuation of one or more valves to drain the liquid from the basin in order to retrieve a first part of the population of insect pupae.

Abstract: A sieving apparatus for separating insect pupa is described. In an example, the sieving apparatus includes a sieving device attached to an actuation system. The sieving device includes a set of openings sized to correspond to a cross-sectional cephalothorax width of a representative pupa of a population of insect pupae to be separated. The actuation system is configured to move the sieving device in a manner that causes smaller insect pupae to pass through the set of openings. Larger insect pupae remain within the sieving device. Such movement can include moving the sieving device with respect to a liquid held in a basin of the sieving apparatus.

Abstract: A sieving device is described. The sieving device includes an adjustable sieve surface that includes a first sieve surface and a second sieve surface. Openings are formed in each of the first sieve surface and the second sieve surface so as to define a shared pathways extending through the adjustable sieve surface. The shared pathways are defined by a length dimension that is greater than a width dimension. The width dimension can correspond to a cephalothorax width of an insect.

Abstract: A sieving device is described. The sieving device includes a sieve surface attached to a sieve rim. A set of openings is formed in the sieve surface so as to define a set of pathways extending through the sieve surface. The set of opening are defined by a length dimension that is greater than a width dimension. When the sieve surface is submerged in a liquid, a first pupa having a first cephalothorax width that is less than the width dimension is free to move through any one of the set of openings, and a second pupa having a second cephalothorax width that is greater than the width dimension is prevented from moving through the set of openings.

Abstract: An apparatus may include a vessel and a first passageway and a second passageway that connect the vessel to a first release container and a second release container, respectively. A first and a second sensor may be positioned proximate to a first and a second release container, respectively. Each sensor may detect an adult insect passing into the respective release container. A first and second shutter may be positioned in the first passageway and the second passageway, respectively. Each shutter may have an open and a closed position to control access to the respective release container. A computing device may receive a first input signal from the first sensor and a second input signal from the second sensor. The first and second shutter may receive a first output signal and a second output signal, respectively, from the computing device to position the respective shutter in the open or closed position.

Abstract: Systems and methods for automated release of insects are disclosed. In one embodiment, a system includes: an insect storage device defining one or more internal compartments to store a population of insects; a loading mechanism for loading the insect storage device with a population of insects; and an insect release device coupled to the loading mechanism and configured to release into an environment one or more insects from the population of insects in the insect storage device.

Abstract: Example insect egg conveyors are disclosed. One example insect egg conveyor device includes multiple rollers positioned along a path and a drive unit that includes a motor connected to a roller of the multiple rollers to drive the roller and rotate the roller. The device also includes a substrate positioned on the roller and a fluid source positioned along the path. The rollers are arranged to move the substrate along the path and toward the fluid source in response to the motor rotating the roller.

Abstract: A sieving apparatus for separating pupa is described. The sieving apparatus includes a frame to support an actuation system and a basin. The actuation system is attached to a sieving device. The sieving device includes a sieve surface supported within a sieve rim. In the sieve surface are formed openings sized to correspond to a representative pupa of a population of pupae to be separated. The actuation system is configured to move the sieving device vertically with respect to the basin. For example, after a population of pupae has been added to the sieving device, the actuation system may move the sieving device into and out of a body of liquid held in the basin. This process of moving the sieving device into and out of the body can be used to separate the population of pupae based on size.

Abstract: Embodiments of the present disclosure can provide an automated mass rearing system for insect larvae. The automated mass rearing system can facilitate hatching, feeding, monitoring the growth and emergence of insect larvae and pupae. In some embodiments, the automated mass rearing system can include a production unit, a transportation unit, a storage unit, a dispensing unit, and a monitoring unit. In some embodiments, this automated mass rearing system can facilitate mass mosquito growth from egg hatching all the way through to full adults or certain stages in between such as the larvae rearing process (i.e., from larvae to pupae) with little or no human intervention. By automating the rearing and transportation of insect eggs, larvae, and pupae, deaths or developmental issues can be minimized. Various techniques and apparatuses are used in this automation that causes minimal disturbance to the insects during development, and thereby maximizing survival rate and fitness of the insects.
