BRIEF DESCRIPTION OF THE INVENTION

[0026] The technology proposed here comprises an adapter, specially designed for coupling to conventional traps, with no need for any changes to the traps, including pest entry dynamics, perforations, and physical structure.

[0027] This adapter comprises a plastic structure adaptable to each conventional trap format, being a device adapted to the dimensions of the conventional traps for counting pest insects, in which it is attached to the trap through its base. The insect then passes through the trap and is conducted directly into the channel of the device, where sensors are positioned, emitting constant signals that, when interrupted by the passage of the insect, carry out an automatic and remote count of the insects. The insects are stored in the counting chamber, in the same way as the system without the adapter. Additionally, the adapter has a slot for the installation of an ultrasonic sensor, which performs the perimeter control of lepidopterans, by mimicking their natural predator (bats).

[0028] The proposed adapter is therefore a dongle that allows the conventional trap counting system to be improved, via the use of sensors.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] The adapter (A) is a rigid plastic modular structure made of ABS type material or similar, of adjustable format to the trap, with an insect passage channel (C), varying in color according to the pest insect and trap that it acts on, supported by a base called support (B), with perforations (P) in the vertical direction throughout its structure, allowing the passage of light, and exhalation of the pheromone/flame and the possibility of its attachment to the structure of the conventional trap, respecting the same angle, between 0° and 90°, of the conventional trap. The opening for the insect-pest passage of the adapter (A) is identical to that of the conventional trap, varying between 5 mm and 30 cm. Along the insect passage channel (C) an extension is projected, where the set of sensors (S) is installed. This extension can be from 0.5 cm to 30 cm. The support (B) of the adapter (A) has the same shape as the conventional trap, with a diameter of 2.5 cm and height of 2 cm.

[0030] The adapter (A) is attached to the conventional trap, through which the insect will move until it exits the conventional trap's capture chamber, since its interest lies in the pheromone inside the chamber.

[0031] The insect when moving through the passage channel (C), interrupts the signal from the set of sensors (S), positioned in a section (R) perpendicular to this passage. The sensors (S), located on a platform (F), used in the adapter (A) can be electrical, optical, mechanical and/or magnetic, such as infrared, piezoelectric, bioimpedance, temperature, humidity, key switch, ultrasonic, among others, depending on the insect-pest to be monitored. These are powered by 3.3V and 5V batteries, with load capacity of 2,000 mAh to 100,000 mAh, and connected by metal wires to the microcontroller, which is inside a plastic cabinet (D) for storing the electric and electronic components. The plastic cabinet (D) is made of rigid plastic material, of ABS-type material or similar, waterproof and UV-resistant, and installed just below the conventional trap, separately.

[0032] The microcontroller installed can be of the Arduino or ESP type, or similar to these, consisting of a processor core, memory, and support that receives the programmable sensors, processes the information received, and sends it to the communication module, which transmits the information through the data network. The insect entering the trap and passing through the first sensor interrupts the signal, and then passing through the second sensor, also interrupting the signal, causes the algorithm to recognize 1 count entering the capture camera. The reverse path, passing through the second sensor, interrupting the signal, and then the first sensor, interrupting the signal, causes the algorithm to recognize 1 output count.

[0033] The algorithm is also designed so that at certain times of the day, the counts performed and stored in the microcontroller's electronic memory, are sent via low-power wide-area network (LPWAN) signals, such as Sigfox or LoRa or similar, to a central web platform (website), which receives the data and sends them to a data management software that will store and process the count information for each installed trap.

[0034] The management software for the captured data accounts for all the information received and projects the results on heat maps, tables, and reports, so that the user can know, in real time, the number of insects that entered and left each geographically identified trap that has the adapter installed, helping in the decision making process.

Demonstration Experiments

[0035] The proposed adapter has its prototype already developed and tested at the laboratory level, for the cotton bollworm insect pest (Anthonomus grandis).

[0036] The laboratory test consisted of: [0037] 1 working trap with the adapter installed. [0038] Release 1 insect, cotton bollworm, and observe its entry into the chamber, [0039] Remove the adapter and repeat the insect entry test [0040] Observation and notes.

[0041] In the laboratory experiment, two traps were set, one conventional and one with the adapter installed, and these traps were placed in an open environment, inside transparent plastic boxes, with 30 insects in each box. At the end of each day the captured insects were removed and counted in the counting chamber of the traps, and then the traps were exchanged from one box to another. The experiment was conducted for 6 days. According to the data in Table 1, the adapter did not represent obstacles to the insects' passage into the counting chamber, showing itself to be an inert element to the operation of the conventional trap, with the advantage of increasing the counting efficiency, automating the process, its final objective.

[0042] Additionally, as it does not alter the operation of a conventional trap, used worldwide, it creates the possibility of using this adapter to automate the process of identification and counting of the insect immediately after its installation.

CONCLUSION

[0043] The adapter complements the monitoring of pest insects through traps, which are widely used worldwide. The traps already in use generate a base of information and confidence in the development of productive activities, but at the same time, they suffer from logistical and human limitations, due to various impediments to monitoring in large areas and making decision-making difficult.

[0044] Conventional traps, with analogical responses and dependent on manual monitoring, are now automatically converted into automatic tools, with instantaneous responses and maintaining all the same dynamics and performance of operation.
