Biology and life table parameters of jasmine whitefly Aleuroclava jasmini on five different species of citrus

Biology of Jasmine whitefly، Aleuroclava jasmini (Takahashi) was studied on tangerine، orange، grapefruit، lime and sour orange under laboratory conditions (27±1oC، 60±5% RH and 14:10 L: D). The mean female immature developmental times on tangerine، orange، grapefruit and lime was recorded as 25. 62±0. 31، 28. 38±0. 34، 26. 74±0. 11 and 21. 76±0. 2 days، respectively. A. jasmini survived as far as first nymphal instar on sour orange. Mean sex ratios (female %) was 53. 32±2. 8، 59. 45±2. 04، 51. 67±1. 15 and 52. 41±2. 48% on above mentioned hosts plants، respectively. Mean immature mortality was 22. 59±1. 08، 26. 53±0. 73، 12. 34±0. 43 and 25. 25±0. 58%، respectively، on the same host plants. The mean adult longevity was 4. 51±0. 1، 3. 40±0. 12، 4. 23±0. 06 and 3. 64±0. 08 days for females، respectively، on the same host plants. Mean total fecundity was 30. 67±2. 41، 25. 53±1. 45، 31. 40±2. 63 and 38. 47±2. 09 eggs، respectively، on the same named host plants. Intrinsic rates of increase (rm) were 0. 093±0. 002، 0. 076±0. 002، 0. 091±0. 001 and 0. 101±0. 002 number of female/female/ day on the above mentioned host plants. Based upon the biological characteristics and life table parameters، lemon was found as the most suitable host for growth and reproduction of A. jasmini.
