During the 2017 season we investigated the occurrence and biology of the brown marmorated stink bug (BMSB), Halyomorpha halys, a new invasive insect pest in two commercial hazelnut orchards located in the Samegrelo Region, Republic of Georgia. The first stink bug adults from the overwintering generation appeared on sticky traps at the end of May, while all instar nymphs and adults were observed at the end of July and through August. The peak occurrence of adults and nymphs in the field was observed at 896-1061 DD 13.9. The wooded areas around orchards supported the development of two BMSB generations. The forested areas and wild vegetation provided the source of continuous influx of the pest into the orchards, while the BMSB influx from a neighboring meadow and abandoned buildings was less important.
Four genera and 12 species of drosophilid flies have been recorded during our survey in five regions of Georgia in 2021. Two genera, Amiota (Loew, 1862) and Gitona Meigen, 1830, and four species (Amiota subtusradiata Duda 1934, Drosophila busckii Coquillett 1901, D. kuntzei Duda, 1924, and Gitona distigma Meigen, 1830) represent new records for the fauna of Georgia (Sakartvelo).
The article deals with sensor-related solutions to improve waste collection and monitoring in public waste bins.
Availability of use of an inexpensive monitoring system for measurement process was tested. The system consists of wireless
nodes that use ultrasonic sensors to measure the empty space in the waste bins. A sensor gateway based on Long Rage
Wide Area Network (LoRaWAN) protocol was used. Purpose of this work was to describe the new sensor node typology
based on low-power and low-cost components. The article analyses the architecture of nodes in detail, focusing on energyefficient
technologies and policies to extend battery life by reducing energy consumption through hardware and software
optimization. Measurements were performed at five points in two size of containers with different two levels of filling and
mixed type of waste. The results show that existing technologies are mature enough to create and deploy inexpensive
additional sensors for outbound bins and that such a system can provide the necessary insights on how to optimize waste
collection processes and avoid overflowing containers.
