UK) was used with a TY9700 digital hygrothermograph
(Tianyue Environmental Protection Technology Co.
was used to measure air temperature and relative humidity (SK-110TRH, SATO, Tokyo, Japan).
Both temperature and relative humidity were recorded on simple graph paper using a hygrothermograph
(Mechel -15+45C, Italy) placed inside the glass house.
Temperature and humidity inside the device were measured by a hygrothermograph
every 4 h when counting the number of psyllids and maintained at 25 [+ or -] 1[degrees]C, 60 [+ or -] 2% RH.
Humidity and temperature were measured with a hygrothermograph
(Control Company--Friendswood, Texas, USA).

2] (which was maximum intensity available within room), and relative humidity ranged from 32 to 46% as measured with a hygrothermograph
Among new products are double junction, waterproof pHTestrs; waterproof pH/con meters; microscopes; and a mini-drum hygrothermograph
The site was instrumented with two automatic weather stations backed up with a hygrothermograph
housed in a standard instrument shelter and a weighing-recording rain gauge.
Temperature was recorded by using the clinical thermometer, minimum-maximum thermometer and hygrothermograph
to minimize the errors.
Environmental temperature and relative humidity were recorded twice daily at 4:00 and 16:00 using a hygrothermograph
(EA-WSD, Huarui Corporation, Beijing).
Temperature and relative humidity were measured by a hygrothermograph
(Oakton, series 025028, Japan) located in the field where the experiment was conducted.
