“…This phenomenon also occurred in females collected from rice plots from late July to late August (Table 4). Similar results were reported by Shi et al (2007) in southeastern Zhejiang, China. Mechanisms responsible for the deposition of yolk proteins in the females, and the fate of the proteins in subsequent diapause maintenance and termination are not clear.…”

“…Mechanisms responsible for the deposition of yolk proteins in the females, and the fate of the proteins in subsequent diapause maintenance and termination are not clear. In earlier studies (Jiang et al 2004a,b;Shi et al 2007), the weevil seemed to possess great variability to enter, maintain and terminate summer diapause and become reproductive. The accumulation of yolk proteins in summer weevils might serve as a physiological preparation for reproduction following diapause termination.…”

“…et al 2006). C. latefasciatus produced more generations (9 Ð12 generations) than other species of Curculionidae in 1 yr, such as C. achates (only one generation) (Goodman et al 2006), C. tamarisci (three or four generations) (Fornasari 1998), and the important invasive rice water weevil, Lissorhoptrus oryzophilus Kuschel (two generations), in southern Zhejiang, China (Chen et al 2005, Shi et al 2007). C. latefasciatus female adults often switched from laying eggs on the surface of leaves to laying eggs into leaves when the temperature was high in the Þeld, a phenomenon that was also observed under laboratory conditions, which may be a good measure for C. latefasciatus to protect its egg at high temperature.…”

Cionus latefasciatus Voss (Coleoptera: Curculionidae) is one of the most important insect pests on Scrophularia ningpoensis Hemsl. (Scrophulariales: Scrophuhrhceae), which is a well-known traditional Chinese medicine plant in southeast China. The biological characteristics and effects of temperature on the growth and development of C. latefasciatus were studied in nature, in the greenhouse, and in the laboratory. In the area studied, 9-12 generations of this weevil occurred per year depending on climatic conditions. The overwintered adults migrated to the plant-seeding fields in the earlier days of March, and adults of the last generation began to overwinter in early October. Female adults lived for 50-75 d and male adults for 50-65 d at 28 degrees C. Adults fed on leaves, buds, tender stems, and flower stalks during the entire developmental phase of the plant. Female adults began to lay eggs 2-4 d after emergence and laid an average of 330-390 eggs per female at 28 degrees C. The eggs were usually laid on the surface of the leaves or into the leaves. The larvae have four instars judging from the width of the cephalic capsule of the larvae. The larvae fed on leaves and buds of the plant. Under constant temperatures (17, 20, 25, 28, and 30 degrees C) and fixed humidity (75%), the development periods from egg to adult emergence were 36.91, 29.25, 19.11, 17.26, and 15.36 d, respectively, and 346.31 degree-days, in total, above a lower threshold of 7.7 degrees C was required; the survival rates from egg to adult emergence were 49.1, 62.5, 72.0, 78.7, and 50.0%, respectively. Laboratory experiments showed that the optimum temperature for the development from egg to adult emergence was 28 degrees C.

“…Two generations of RWW occur annually which attack first-and second-season rice, respectively, and normally only the first generation has high densities (Zhai et al, 1997;1999;Shi et al, 2007). In transplanted fields, overwintered RWW adults, first-generation larvae and pupae occur from early to mid-May, mid-May to late June and mid-June to early July, respectively (Zhai et al, 1997).…”

Abstract:The rice water weevil (RWW) Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae) is an invasive insect pest of rice Oryza sativa L. in China. Little is known about the interactions of this weevil with indigenous herbivores. In the present study, adult feeding and population density of the weevil, injury level of striped stem borer Chilo suppressalis (Walker) (Lepidoptera: Pyralidae) and pink stem borer Sesamia inferens (Walker) (Lepidoptera: Noctuidae) to rice, as well as growth status of their host plants were surveyed in a rice field located in Southeastern Zhejiang, China, in 2004 with the objective to discover interspecific interactions on the rice. At tillering stage, both adult feeding of the weevil and injury of the stem borers tended to occur on larger tillers (bearing 5 leaves) compared with small tillers (bearing 2~4 leaves), but the insects showed no evident competition with each other. At booting stage, the stem borers caused more withering/dead hearts and the weevil reached a higher density on the plants which had more productive tillers and larger root system; the number of weevils per tiller correlated negatively with the percentage of withering/dead hearts of plants in a hill. These observations indicate that interspecific interactions exist between the rice water weevil and the rice stem borers with negative relations occurring at booting or earlier developmental stages of rice.
