“…Similar phenomena have been reported for other species of Homoptera. For example, high mortality also was reported for the fifth instar of the potato leafhopper, Empoasca fabae (Harris) Simonet and Pienkowski (1980), the blackfaced leafhopper, Graminella nigrifrons (Forbes) (Sedlacek et al 1986), the bean aphid, Aphis fabae (Scop.) (Tsitsipis and Mittler 1976).…”

Effect of temperature on development, mortality, fecundity, and reproduction of Aphis rumicis L. (Homoptera: Aphididae) on broadleaf dock (Rumex obtusifolius) and Swiss chard (Beta vulgaris vulgaris var. cida) Abstract Temperature effects on developmental period, survival rate, and reproductive capacity of Aphis rumicis L. were studied on Broadleaf dock and Swiss chard at four constant temperatures (17.5°C, 20°C, 22.5°C, and 25°C). The developmental time of immature stages ranged from 10.9 days at 17.5°C to 6.5 days at 25°C on Broadleaf dock, and 11.8 days at 17.5°C to 6.5 days at 25°C on Swiss chard. The total percentage of survivorship of immature stages varied from 54.2% and 67.6% 17.5°C-25°C on Broadleaf dock, and 49.7% and 62.4% at 17.5°C-25°C on Swiss chard. The largest r m value occurred with 0.2845 at 25°C on Broadleaf dock and with 0.2785 at 25°C on Swiss chard. The results obtained on this study indicated that Swiss chard was a less favorable host of the A. rumicis than Broadleaf dock. The optimal temperature for A. rumicis growth, developmental time, and reproduction was 22.5°C-25°C.

“…Mortality was greatest in the 1st and 5th instar nymphs. Simonet & Pienkowski (1980)found a similar situation with the potato leafhopper Empoasca fabae (Harris), and suggested this was probably because of major changes that the 5th instar was undergoingbefore development to adult, and to handling in the case of lst instar nymphs. The causes of mortality among 1st and 5th instars in this study were probably similar.…”

Development ofTyphlocyba froggattiBaker (Homoptera: Cicadellidae) and determination of lower threshold temperatures

Development of Typhlocyba froggatti Baker (Homoptera: Cicadellidae) was examined in the laboratory at six temperatures. Time for development from egg to adult varied from 118 days at 13°C to 31 days at 2Ye. Lower threshold temperatures for development of life stages established from this data and by the least variability method proposed by Arnold (1959) were contradictory. The use of these methods is discussed.

“…In the laboratory, the average developmental time from Þrst to third instar is about 4 d, whereas development from third instar to adult is about 10 d (Simonet and Pienkowski 1980). The developmental times for the potato leafhopper on FGplh13 with the trichomes removed and P5373 with trichomes intact or removed were slightly shorter, which could be attributed to more optimal conditions being provided by the environmental growth chamber.…”

Experiments were performed to elucidate resistance of glandular-haired alfalfa, Medicago sativa L., to the potato leafhopper, Empoasca fabae (Harris). The primary objective was to examine the potential role of the glandular trichomes and stem lignification for imparting resistance to this pest. During free-choice foliar discoloration experiments, the resistant alfalfa clone FGplh13 expressed lower levels of injury than the susceptible P5373 after 13 d. No-choice tests performed using nymphal potato leafhoppers showed higher levels of mortality associated with the resistant glandular-haired clone FGplh13, and no nymphs survived after 48 h. Additional no-choice experiments using FGplh13 and P5373 alfalfa with the glandular and nonglandular trichomes intact or removed show that mortality of nymphs and adults decreased after removal of the glandular trichomes from FGplh13. Nymphal and adult mortality and nymphal development time did not differ on FGplh13 with the trichomes removed and P5373 with the trichomes intact or removed. Firstinstar, and possibly second-instar, potato leafhoppers were entrapped by an exudate produced by the glandular trichomes on the FGplh13 alfalfa. Stem lignification and the number of vascular bundles did not differ between FGplh13 and P5373 alfalfas. The glandular trichomes on FGplh13 alfalfa appeared to provide the major host resistance factor, with resistance to adults being chemically based and resistance to nymphs being chemically and mechanically based. To maintain levels of potato leafhopper resistance, breeders would appear to benefit by continuing to select for the expression of the glandular trichome phenotype.
