Automatic monitoring of insect populations

Abstract

Illustrative embodiments of integrated pest management (IPM) systems and electronic insect monitoring devices (EIMDs) are disclosed. In some embodiments, the EIMDs may each comprise a lure for attracting at least one target insect species, one or more sensors configured to generate one or more output signals in response to an individual insect approaching the lure, and an electronic controller configured to count a number of individual insects approaching the lure. In some embodiments, the IPM system may comprise a plurality of EIMDs configured to communicate over a wireless network shared by the plurality of EIMDs.

1 . An electronic insect monitoring device (EIMD) comprising:
 a lure for attracting at least one target insect species;   one or more sensors configured to generate one or more output signals in response to an individual insect approaching the lure; and   an electronic controller configured to count a number of individual insects approaching the lure.   
     
     
         2 . The EIMD of  claim 1 , wherein the electronic controller is configured to determine if the individual insect approaching the lure belongs to the at least one target insect species by analyzing at least one of a slope, an amplitude, a rise time, a fall time, a width, and a ringing frequency of an electrical pulse of the one or more output signals. 
     
     
         3 . The EIMD of  claim 1 , further comprising one or more additional sensors selected from the group consisting of bio-impedance sensors, ultrasonic sensors, and optical sensors, the one or more additional sensors configured to generate one or more output signals in response to an individual insect approaching the lure. 
     
     
         4 . The EIMD of  claim 3 , wherein the electronic controller is configured to determine if the individual insect approaching the lure belongs to the at least one target insect species by applying a sensor fusion algorithm to the one or more output signals generated by the one or more sensors and the one or more additional sensors. 
     
     
         5 . The EIMD of  claim 1 , further comprising a communication module for wirelessly communicating with neighboring EIMDs. 
     
     
         6 . The EIMD of  claim 1 , further comprising a global positioning system module for determining a deployment location of the EIMD. 
     
     
         7 . The EIMD of  claim 1 , further comprising a battery that supplies power to the electronic controller and to the one or more sensors via a power controller, wherein the power controller is configured to implement an active duty-cycling scheme to conserve the power supplied by the battery. 
     
     
         8 . The EIMD of  claim 1 , further comprising an insect collector having at least one inwardly sloped upper surface. 
     
     
         9 . The EIMD of  claim 1 , further comprising a housing containing the electronic controller, wherein the housing is configured to be interchangeably fitted with one of a delta-shaped insect collector and a bucket-shaped insect collector. 
     
     
         10 . The EIMD of  claim 1 , wherein the at least one target insect species comprises one or more moth species. 
     
     
         11 . The EIMD of  claim 1 , wherein the at least one target insect species comprises one or more of  Cydia pomonella, Grapholita molesta, Archips argyrospila,  and  Choristoneura rosaceana.    
     
     
         12 . The EIMD of  claim 1 , wherein the at least one target insect species comprises one or more of  Plodia interpunctella, Ephestia kuehniella, Lasioderma serricorne,  and  Trogoderma variabile.
