“…However, there is no conclusive evidence whether the thrips can overwinter in fields of northern Japan. Furthermore, no detailed study has been reported on the cold hardiness of the Japanese strain, even though the cold hardiness of the Denmark strain (Brøds-gaard, 1993), the English strain (McDonald et al, 1997a, b, c) and the American strains (Chamberlin et al, 1992;Felland et al, 1993) have been reported. The thrips undergoes no reproductive diapause under short photoperiods (Ishida et al, 2003).…”

The cold hardiness in adult males and females of Frankliniella occidentalis (Pergande) reared at different conditions were investigated. Supercooling points (SCPs) were about Ϫ26°C in both males and females. The SCPs were not affected by the rearing conditions of photoperiod and temperature. However, the survival periods of males and females at low temperatures from Ϫ15°C to 5°C were predominantly affected by rearing temperatures. Males and females reared at 15°C survived longer at the low temperatures than those reared at 20°C. Females survived for much longer than males at the low temperatures except Ϫ15°C. Furthermore, the survival periods of males and females at the low temperatures were affected by water and food applications. However, the effects were smaller in both males and females at 0°C from Ϫ5°C for 12 h to ϩ5°C for 12 h than 5°C, especially less water effect was observed in males at 0°C. Males and females given food maximally survived for about 30 d and 40 d at 0°C, and about 40 d and 60 d at 5°C, respectively. These results show that F. occidentalis can overwinter only in relative mild winter or artificial conditions.

“…After overwintering on susceptible weed hosts primarily as brachypterous females (Chamberlin et al, 1992;Cho et al, 1995;Brown et al, 1996), thrips begin dispersing to new hosts in late March and early April (Groves et al, 2003). In North Carolina, movement of thrips vectors among weed hosts in late winter and spring results in spread of TSWV among weed hosts and an increase in source of TSWV prior to peak flights of tobacco thrips, which typically occur in midto late-May (Eckel et al, 1996;Groves et al, 2002Groves et al, , 2003.…”

Thrips moving into the field during the spring are mostly from nearby sources, and these populations of thrips provide the primary source of inoculum (Todd et al, 1990;Chamberlin et al, 1992;Camann et al, 1995;Brown et al, 1996;Groves et al, 2003). Thrips may also migrate into fields on wind currents (Todd et al, 1990;Mound, 1996).…”

Effect of Cultivar and Plant Population on Spotted Wilt in Virginia Market-Type Peanut

Field experiments were conducted in North Carolina during 2001 and 2002 to evaluate the impact of cultivar and plant population on the incidence of symptoms of tomato spotted wilt virus, which is transmitted primarily by tobacco thrips [Frankliniellafusca (Hinds) (Thysanoptera: Thripidae)]. Treatments included the virginia market-type cultivars Gregory, NC-V 11, and Perry seeded at in-row plant populations of 7, 13, and 17 plants/m. In these experiments, there was a consistent trend for increased foliar injury from thrips as plant population decreased. Less thrips feeding 'Former Grad. Res. Asst., Prof., and Prof., respectively, Dept. injury was noted for Gregory and Perry than for NC-V 11. Incidence of visual symptoms of spotted wilt (SW) was recorded from mid-June through mid-September. A plant condition rating was recorded late in the season. Consistent with the results for thrips-induced injury, the percentage of plants infected with SW and the plant condition rating increased as plant population decreased. Gregory had the lowest SW incidence, while NC-V 11 was intermediate between Gregory and the most susceptible Perry. Establishing higher plant densities and planting Gregory rather than NC-V 11 or Perry reduced SW incidence and plant condition rating. Gregory had consistently the highest %ELK (extra large kernels) and %FP(fancy pods) across treatments and locations whereas no definitive trend in market grade characteristics were noted among treatments. In some cases, Perry had a higher incidence of SW, but still had higher pod yields than NC-V 11 with a lower incidence of SW. However, in most cases pod yield correlated with plant condition ratings, and as thrips injury increased, pod yield decreased.

“…Frankliniella occidentalis (Pergande), western flower thrips also occurs in peanut producing areas in North Carolina, but are rarely found on peanut foliage (Eckel et al, 1996;Groves, 2001;Groves et al, 2003). F. occidentalis is known to reproduce poorly on peanut, while peanut serves as a good host for reproduction of TT (Chamberlin et al, 1992;Todd et al, 1995). Only adult thrips and late instar larvae (Wijkamp and Peters, 1993;Wijkamp et al, 1995;Wetering et al, 1996) that acquired the virus as first instars can transmit TSWV to plants.…”

Tomato spotted wilt virus (TSWV), a thripsvectored tospovirus, is an important pathogen of peanut (Arachis hypogaea L.). Development of tolerant cultivars has proven to be one of the most promising methods to manage the disease. Twenty-four genotypes of virginia market-type peanut were monitored in field tests for thrips damage, and TSWV incidence and severity during 2004 and 2005 in North Carolina. The cultivar Gregory had a higher density of adult thrips in foliage than any other genotype, while breeding lines N01057 and N03054E had the lowest density. No significant correlation was detected between thrips density or injury and TSWV incidence. Line N03036EJ had the greatest TSWV incidence, but did not differ from cultivars Gregory or Perry in incidence. Line N00033 had the least TSWV incidence and differed from the cultivars Gregory and Perry. The occurrence of late-season chlorosis or peanut yellowing death (PYD) was highly correlated with TSWV infection (P , 0.0001). Breeding line N02051ol had the greatest incidence of PYD, but did not differ statistically from Gregory or Perry. Lines N03023EF and N01083 had the least PYD incidence. Plants infected with TSWV not expressing foliar symptoms were found in far greater abundance than plants that were infected and symptomatic. Line N03036EJ had the greatest proportion of infected but asymptomatic plants; line N03054E had the least. Susceptible lines are more likely to become infected, rather than just more likely to show spotted wilt symptoms.
