“…Our results are in close corroboration with the findings of Salas (1994) who reported that thrips take 12.03 days from egg to adult at a temperature of 32°C and 60 per cent relative humidity on onion. In contrast to our findings van Rijn et al, (1995) reported that that the development period from egg to adult stage was 12.90±0.89 during their comparative study on cucumber at 25°C.…”

“…Our results are in line with the findings of Murai (2000) who reported that female longevity was 25±10.2 at constant temperature of 25°C and 12.8±4.6 days at constant temperature of 30°C on pollen and honey solution. Our results are also in close proximity with the study of Salas (1994) who reported that at 32°C temperature and 60 per cent relative humidity, the longevity of thrips female was 21.5±3.69 days on onion. Salmasi et al, (2003) found that the females lived for 16.15 days on onion at 27°C.…”

“…Lall and Singh (1968) recorded the pre-pupal and pupal period of 1.40 days and 2.40 days, respectively at 30.8°C on onion. Similarly, Salas (1994) recorded that pre-pupal and pupal period of T. tabaci was 1.17 and 2.4 days, respectively at 32°C and 60 per cent relative humidity.…”

“…Whereas, Murai (2000) revealed that total number of eggs per female was 165±84.8 at constant temperature of 25°C and 62.6±35.9 at constant temperature of 30°C on pollen and honey solution. Salas (1994) reported the fecundity of thrips was 37 eggs per female and fertility was 62.28 per cent on onion at 32°C temperature and 60 per cent relative humidity. The difference in the values of fecundity may be due difference in host species and due to difference in environmental conditions.…”

“…In this study, the immature development time of T. tabaci was determined to be 12.3-16.9 days on Talayh and RGS003, respectively. It has been reported that the development time of immature stages of T. tabaci differs on various host plants (Salas 1994;van Rijn et al 1995;Salmasi et al 2003). The reported values are: 12.3 days on onion (Salas 1994), Appl Entomol Zool (2011 11.1 days on onion (Salmasi et al 2003), 12.9 days on cucumber (van Rijn et al 1995), 14.7 and 15.2 days on onion in the Khorasan and Golestan populations, respectively, and 19.5 days at 25°C on tobacco in the Mazandaran population (Fekrat et al 2009).…”

Life history parameters of Thrips tabaci (Thysanoptera: Thripidae) on six commercial cultivars of canola

The onion thrips, Thrips tabaci Lind. (Thysanoptera: Thripidae), is an important pest of the canola crop, Brassica napus L., in the Ardabil region. In this study, life history parameters of T. tabaci were investigated on six canola cultivars, namely: Talayh, Zarfam, RGS003, Opera, Option500, and Hayola401. Experiments were performed in a climate chamber set at 25 ± 1°C and 55 ± 5% RH under 16L:8D. The results indicated that the development time of immature stages was significantly longer on RGS003 than on Opera, Hyola401, Zarfam, Option500, and Talayh. The onion thrips reared on RGS003 had the lowest number of eggs laid per female (15.5) and the lowest survival rate (40%) among the tested cultivars. The lowest intrinsic rate of natural increase (r m ) and population growth rate (k) were observed on RGS003, and were the highest on Zarfam. The generation time (T) was shortest on Zarfam (21.5 days) and longest on RGS003 (26.5 days). Similarly, the doubling time (DT) was shortest on Zarfam (4.5 days) and longest on RGS003 (8.1 days). Considering the significant effect of the host plant on the life history parameters of onion thrips, it was concluded that RGS003 is the least suitable cultivar among the other tested canola cultivars for integrated management of onion thrips in canola fields.

Onion thrips, Thrips tabaci Lindeman, were collected from commercial onion fields in 2001, 2002 and 2003 to assess resistance to lambda-cyhalothrin, deltamethrin and diazinon. In 2001, six of eight adult populations were resistant to lambda-cyhalothrin, with resistance ratios (RR) ranging from 2 to 13.1 and four of these were also resistant to deltamethrin, with RR ranging from 19.3 to 120. Three of four adult populations were resistant to diazinon with RR ranging from 2.5 to 165.8. In 2002, four of seven nymphal populations and three of six adult populations were resistant to deltamethrin, with RR ranging from 4.3 to 72.5 and 9.4 to 839.2, respectively. Only one of six nymphal populations and one of five adult populations were resistant to diazinon, with RR of 5.6 and 2.3, respectively. In 2003 diagnostic dose bioassays, 15 of 16 onion thrips populations were resistant to lambda-cyhalothrin and all were resistant to deltamethrin. Eight of the 16 were resistant to diazinon. These results indicate that insecticide resistance is widespread in onion thrips in commercial onion fields in Ontario.
