Abstract

A rearing device for black soldier fly larvae includes a first insect fattening container that accommodates a first insect larvae cohort for fattening, an activity sensor device, and a processing unit. The activity sensor device detects a humidity measurement value at an insect fattening container humidity measurement point and provides the value to the processing unit. The insect fattening container humidity measurement point is in a central section of the insect fattening container. The activity sensor device also detects a temperature measurement value at an insect fattening container temperature measurement point and provides the value to the processing unit. The insect fattening container temperature measurement point is in the central portion of the first insect fattening container. The processing unit is designed to process the measured humidity value and the measured temperature value and to determine the activity of the black soldier fly larvae based on the processing.

Dependent claims

A black soldier fly larvae rearing device, comprising:

a first insect fattening container configured to accommodate a first cohort of insect larvae for fattening;
an activity sensor device;
and
a processing unit,
wherein the activity sensor device is configured to detect at least one first humidity measurement value at a first insect fattening container humidity measurement point and to provide the at least one first humidity measurement value to the processing unit,
wherein the at least one first humidity measurement point is disposed in a central portion of the first insect fattening container,
wherein the activity sensor device is configured to detect at least one first temperature measurement value at a first insect fattening container temperature measurement point and to provide the at least one first temperature measurement value to the processing unit,
wherein the at least one first temperature measurement point is disposed in the central portion of the first insect fattening container, and
wherein the processing unit is configured to process the detected first humidity measurement value and the detected first temperature measurement value and to determine an activity of the insect larvae based on the processing.

A method for determining activity of black soldier fly larvae, the method comprising:

filling a first insect fattening container with insect larvae with and fattening substrate at the start of a fattening phase;
and
processing a detected first humidity measurement value and a detected first temperature measurement value at a first time t1 by:
A1) Comparing the detected first humidity measurement value at time t1 with a first humidity reference value at time t1, comparing the detected first temperature measurement value at time t1 with a first temperature reference value at time t1;
B1) Determining a reference value undershoot at time t1 in the event that one or more of the detected measurement values falls below the respective reference value;
C1) Determining a reference value overshoot at time t1 in the event that one or more of the detected measurement values exceed the respective reference value;
D1) Determining a cluster formation of the insect larvae at time t1 at one or more of the humidity and/or temperature measuring points in the event that a reference value overshoot was detected at said one or more humidity and/or temperature measuring points at time t1;
E1) Comparing the determined cluster formation of the insect larvae at time t1 with a reference cluster formation of the insect larvae at time t1;
F1) Determining a regular activity of the insect larvae at time t1 in the event that the determined cluster formation of the insect larvae at time t1 corresponds to the reference cluster formation of the insect larvae at time t1;
G1) Determining an irregular activity of the insect larvae at time t1 in the event that the determined cluster formation of the insect larvae at time t1 deviates from the reference cluster formation of the insect larvae at time t1;
and
H1) Outputting a development status signal at time t1 depending on the determined activity of the insect larvae at time t1.
