Última Test of hypotheses about herbivory and chemical defences of Qualea parviflora (Vochysiaceae) in Brazilian Cerrado Rev. Bras. Bot. Gonçalves-Alvim,Silmary J.; Lana,Tate C.; Ranieri,Bernardo D.; Fernandes,Geraldo Wilson. (Test of hypotheses about herbivory and chemical defences of Qualea parviflora (Vochysiaceae) in Brazilian Cerrado). Qualea parviflora Mart. (Vochysiaceae), a widely distributed tree found in different habitats in Brazilian Cerrado (savanna), provides resources for a great variety of insects. In this study, we tested two hypotheses about plant investment in anti-herbivore defences along a fertility gradient in Cerrado: the carbon/nitrogen balance (CNBH) and resource availability (RAH). We also investigated how the pattern of herbivory varies through the year and among three types of vegetation in Brazilian Cerrado - campo sujo, cerrado sensu strictu and cerradão. Sampling was conducted in three types of vegetation and in rainy (January and November) and...

Studies on the communities of galling insects and their host plants were performed in three "cerrado" physiognomies that occur in Minas Gerais: "campo sujo", "cerrado" sensu strictu, and "cerradão". Galls and host plants were collected along transects in a total of 3,000 herbs, 300 shrubs and 135 trees in each physiognomy. Ninety two species of galling insects (morphotypes) on 62 host plant species of 28 families were found. The highest galling insect richness was observed in the "cerrado". Approximately 75.0% of galling insects belonged to the Cecidomyiidae (Diptera). The highest gall frequency was found on leaves (58.70%) of the host plants, and was glabrous (83.70%). Most gall shape were elliptic (30.43%). A low similarity in galling insect species was...

The plant-vigor hypothesis (PVH) predicts that females of galling insects preferentially oviposit on the most vigorous plant or plant modules, where their offspring performance is highest. We tested the PVH on Neopelma baccharidis Buckhardt (Homoptera: Psyllidae) and Rhoasphondylia friburgensis Tavares (Diptera: Cecidomyiidae) which induce galls on Baccharis dracunculifolia D.C. (Asteraceae), and on two different Cecidomyiidae (Diptera) species that induce galls on Maytenus salicifolia Reiss. (Celastraceae) and Vernonia polyanthes Less (Asteraceae), respectively. The abundance of galls induced by the four galling species increased with increasing shoot length, as predicted by the PVH. However, when we considered the rate of attack per shoot unit length...

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...
