Temporal patterns in Homalodisca spp. (Hemiptera: Cicadellidae) oviposition on southern California citrus and jojoba.
A detailed study of the distribution of egg masses of Homalodisca vitripennis (Germar) and H. liturata Ball was done across a 2-yr period (2001-2003) on six host plants in southern California (Marsh grapefruit, Lisbon lemon, Washington navel, Dancy tangerine, rough lemon, and jojoba in Riverside; jojoba in Desert Center). The majority of egg masses in Riverside belonged to H. vitripennis (84-10...
متن کاملPhenology and demography of Homalodisca coagulata (Hemiptera: Cicadellidae) in southern California citrus and implications for management.
Populations of Homalodisca coagulata (Say) were sampled from citrus orchards in southern California, USA to characterize and quantify seasonal occurrences of nymphs and adults with the goal of identifying management opportunities through well-timed treatments and/or natural enemy releases. Higher densities of H. coagulata in 2001 contributed to a complete seasonal profile that began in early sp...

Oviposition of Graphocephala atropunctata (Signoret) (Hemiptera: Cicadellidae), the blue-green sharpshooter, was assessed on wild grape, Vitis girdianaMunson, in southern California. Female blue-green sharpshooter preferred to oviposit into new growth, primarily succulent young grape tendrils and canes. Themidrib and petioles of small grape leaves also were used for oviposition, but to a lesser...
متن کاملPOPULATION ECOLOGY Seasonal Patterns of Female Homalodisca coagulata (Say) (Hemiptera: Cicadellidae) Reproductive Physiology in Riverside, California
Female Homalodisca coagulata (Say) were collected from October 2001 to February 2005 from citrus at theUniversity of California, Riverside. Between 5 and 20 females per sampling date were dissected, and each was assigned an ovarian rank: previtellogenic, vitellogenic, or postvitellogenic. Ovarian ranking was used to characterize H. coagulata reproductive activity. Results of these dissections r...
متن کاملComparison of sampling methods for determining relative densities of Homalodisca vitripennis (Hemiptera: Cicadellidae) on citrus.
Four sampling methods that included A-Vac, D-Vac, pole-bucket, and beat-net devices were evaluated for estimating relative densities of glassy-winged sharpshooter, Homalodisca vitri-pennis (Germar) (Hemiptera: Cicadellidae) nymphs and adults on citrus (Citrus spp.) trees. All four methods produced similar temporal and spatial distribution profiles, although significant differences in quantities...
