摘要:
The objects of the present invention are to achieve year-round utilization of pollinating insects such as bumble bees and to provide a constant temperature box (1) to be employed for this purpose. In order to achieve the objects, the temperature inside the nest box (2) for housing pollinating insects such as bumble bees is maintained within an optimal habitat environment temperature range throughout the year. In the constant temperature box (1) for maintaining the temperature within the optimal habitat environment temperature range, the temperature in the space where the nest box (2) for housing pollinating insects such as bumble bees is placed is maintained within the optimal habitat environment temperature range for pollinating insects such as bumble bees through a means for temperature control. In addition, the constant temperature box is provided with a means for access (15) to allow the pollinating insects in the nest box to come and go between the nest box and the outside.
摘要:
The present invention makes it an object to increase an attracting rate of flying insects by enlarging diffusion area of light radiated out of a case from a lamp for attracting flying insects as well as to make the flying insects caught inside the case not to be seen through openings from below. A case (2) of a device for catching flying insects (1) is formed in a polygonal shape more than a pentagon in a cross section view thereof including at least vertical portions (11), an upper slant portion (13) and a lower slant portion (14), openings (15) through which the flying insects invade are provided in the vertical portions (11), the upper and lower slant portions (13, 14), and a plurality of plates (17) are provided in the openings (15) in the lower slant portions (14), so that the flying insects caught by a sheet for catching insects (5) located inside the case (2) may not be recognized from below.
