Última Response of the galling insect Aciurina trixa Curran (Diptera: Tephritidae) to host plant quality Anais da SEB Fernandes,Geraldo W.; Price,Peter W.; Gonçalves-Alvim,Silmary J.; Craig,Timoty P.; Yanega,Douglas. Female host plant selection, oviposition behavior, and offspring performance of the gall-forming tephritid Aciurina trixa Curran (Diptera: Tephritidae) on NPK-fertilized and control plants of Chrysothamnus nauseosus hololeucus Pall. (Britton) (Asteraceae) were studied in northern Arizona, USA. There was no statistically significant difference in the proportion of females that selected control versus fertilized plants, and between the time to accept control versus treatment plants. Females laid fewer eggs and spent a longer time ovipositing on control plants than on treatment plants. Larval performance (measured as time of first gall appearance on plant, gall diameter, and larval weight) was not statistically different between fertilized and control plants...

S.; Price,Peter W.; Oliveira,Regina C. de. Eleven species of native or naturalized grasses were found hosting spittlebug nymphs in the natural grassland areas around Brasília in the Fe-deral District of Brazil. A large number of nymphs were found on the species Axonopus marginatus (Trin.) Chase. Out of a total of 224 observed nymphs, 85.7% were found feeding on A. marginatus. Apparently the presence of the spittlebug nymphs in the cerrado vegetation, the Brazilian savanna, was associated with any form of disturbance, such as cattle grazing and partial deforestation. Nymphs were found only in disturbed areas of the "cerrado campo sujo" and in the cerrado sensu strictu. The densities of spittlebug nymphs in the cerrado were lower than the density found in the cultivated pasture. The nymphal density...
