Biology of the Lonicera whitefly, Aleyrodes lonicerae Walker (Hemiptera: Aleyrodidae) were studied on rose, Rosa sp. (Rosaceae) plants. Whitefly adults were collected from Mercurialis annua L. (Euphorbiaceae) plants in Adana. The development duration of egg, first, second, third, fourth larval (pupa) stages, total of A. lonicerae on Rosa sp. plants at 20°C were 8.44, 5.44, 5.50, 4.50, 5.19 and 29.07 days for the females and 8.15, 5.46, 5.92, 4.92, 5.38, 29.83 days for the males respectively. The development duration of egg, first, second, third, fourth larval (pupa) stages, total of A. lonicerae on Rosa sp. plants at 25°C were 8.00, 1.67, 2.33, 2.67, 9.67, 24.34 days for the females and 7.67, 2.33, 2.33, 3.33, 7.83 and 23.49 days for the males respectively. The mortality rate (%) of egg, first, second, third, fourth larval (pupae) stages of A. lonicerae at 20 and 25°C temperatures were 14.70, 13.97, 25.00, 20.58, 4.41; 2.89, 24.65, 26.08, 20.28, 13.06 respectively. The biggest k values at 20 and 25°C on rose plants were 0.2553 for the third larval stage and 0.3010 for the fourth larval stage, respectively.

Biology of the lonicera whitefly, Aleyrodes lonicerae Walker (Aleyrodidae: Hemiptera) were studied on violet, Viola tricolor L. (Violaceae) plants. Whitefly adults were collected from Mercurialis annua L. (Euphorbiaceae) plants in Adana. The development duration of egg, first, second, third, fourth larval (pupa) stages of A. lonicerae on V. tricolor were 9.17, 6.33, 5.83, 4.00, 5.17 and 30.50 days for the females and 10.27, 5.91, 5.55, 4.82, 4.55 and 31.10 days for the males, respectively. The total development duration from egg to adult of female and males of A. lonicerae were 30.50 and 31.10 days. The mortality rate (%) of egg, 1., 2., 3. and 4. larva (pupae) stages on violet leaves were 22.45, 18.37, 12.25, 4.08 and 8.16, respectively. According to life table depending on pre-adult stages on violet plants, the biggest k value determined was for the first larvae stage (k=0.1174). At the same time, the k-values determined indicated the stage with the highest mortality rates. In the studies conducted for host plant preference, the average numbers of eggs deposited by the females of A. lonicerae were significantly different between rose (2.67/two leaves) and violet (15.83/two leaves) in the same experimental area. The study was conducted in a climate-controlled room in at 20±2°C, 40%±5 relative humidity.
