The apparatus according to the present invention is provided with two or more output systems to which transducers are connected, a source output on/off control unit that turns on/off the output from a source based upon the output from a random signal generating unit and a frequency varying unit that causes changes in the frequency of an electrical signal provided to the transducers over time at a specific rate. Every time the source output is turned off, the output of the electrical signal is stopped and the output systems are switched over, whereas when the source output is on, the electrical signal provided to the transducers on the output system to which the signal is to be provided. Since the output systems are switched over to be selected for use, it becomes possible to connect a greater number of transducers while using the same source capacity as in the prior art and noise generated from the transducers, when switching over the output systems, is eliminated.

A method of achieving year-round utilization of pollinating insects such as bumble bees and a constant temperature box to be employed for this purpose. In order for this to be achieved, the temperature inside the nest box 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 for maintaining the temperature within the optimal habitat environment temperature range, the temperature in the space where the nest box 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 device for temperature control. In addition, the constant temperature box is provided with a communication passage for access to allow the pollinating insects in the nest box to come and go between the nest box and the outside.

In order to provide a termite detection apparatus that is capable of detecting an infestation of termites in a reliable manner and a termite alarm unit that employs this termite detection apparatus, the termite detection apparatus according to the present invention comprises a sensor section. The sensor section comprises a case, an attractant member provided inside the case and a detection portion provided with a for detection mechanism where the attractant member is provided to detect termites that have entered, attracted by the attractant member. The termite detection apparatus also includes a sensor cover enclosing an area around the sensor section. In addition, the termite alarm unit gathers termite detection signals sent from a plurality of such termite detection apparatuses at a relay device, sends the termite detection signals gathered at the relay device to an alarm section as a termite presence signal so that a warning can be issued to the resident with a voice produced at an audio alarm section and with a visual indication made at a visual alarm section.

A cellulose-containing member is provided with a plurality of holes transversely extending therethrough. An emitting element and a receiving element are located at opposite ends, respectively, of each of the holes. The presence or absence of termites is detected by the obstruction of an output wave from the emitting element caused by termites invading the holes, whereupon a detection signal is generated to cause alarm lamps and so on to light up for alarm display. Simultaneously, in order to estimate the number of invading termites, the number of occurences of an obstruction by the termites of the output waves from the emitting elements is counted.
