ABSTRACT

ABSTRACT Among the plant diversity of the Cerrado, the genus Copaifera is commonly associated with galling insects. Here, we expand the knowledge about insect galls on Copaifera sabulicola J.A.S Costa & L.P. Queiroz (Fabaceae) by characterizing their occurrence in a stricto sensu vegetation area of the Brazilian Cerrado, Western Bahia, Brazil throughout the year. We randomly sampled 60 branches (50 cm long) from individuals of C. sabulicola, from April 2015 to March 2016. We found 11 morphotypes for C. sabulicola, of which 5 are new records. Further, we identified six gall-inducing insects, all belonging to Cecidomyiidae family. Regarding other arthropods associated with C. sabulicola, we observed inquilines, successors, and parasitoids, belonging to the orders Collembola, Hemiptera, Hymenoptera and Acari. The parasitoid fauna included three families of the order Hymenoptera: Braconidae, Encyrtidae and Eulophidae.

ABSTRACT

Abstract The aim of this study was to characterize galls of three species of the Copaifera genus (C. sabulicola, C. luetzelburgii and C. depilis), which occur sympatrically in a Cerrado area from Bahia state. A total of 23 gall morphotypes were found, 9 morphotypes on C. sabulicola, 7 on C. luetzelburgii and 7 on C. depilis. Galls predominated on leaves and stems. The most abundant colours found among galls were brown and green. Regarding the period of the year, from 35,511 leaflets analysed, 16,322 were collected in the dry season and 19,189 in the rainy season. In the dry season, 1,635 leaflets having galls were observed, and the highest proportion was observed on C. luetzelburgii (16.31%). In relation to the rainy season, there is statistical difference in the incidence of leaflets with galls between C. sabulicola and C. depilis, these two species are affected differently during the rainy season. In general, most of the gall morphotypes were more abundant in the dry season. The gallers of 18 morphotypes cannot be determined, because the gall samples were collected occupied by parasitoids or without dwellers. Cecidomyiids induced galls in five morphotypes. Associated invertebrates belonging to the orders Hymenoptera, Diptera, Coleoptera and Acari were found among all gall morphotypes. The results obtained here indicate that the three species of Copaifera have an expressive number of galls, but lower than reported in the literature for C. langsdorffii, which is considered a super host.


Resumo O objetivo deste trabalho foi caracterizar as galhas de três espécies do gênero Copaifera (C. sabulicola, C. luetzelburgii e C. depilis) que ocorrem em simpatria no Cerrado do Estado da Bahia. Um total de 23 morfotipos de galhas foi encontrado, sendo 9 morfotipos em C. sabulicola, 7 em C. luetzelburgii e 7 em C. depilis As galhas predominaram nas folhas e caules e os morfotipos com coloração marrom e verde foram os mais abundantes. Em relação à época do ano, do total de 35.511 folíolos analisados, 16.322 foram coletados no período seco e 19.189 no chuvoso. Na estação seca foram observados 1.635 folíolos com galhas, sendo que a maior proporção de folíolos galhados foi observada em C. luetzelburgii (16.31%). Já em relação à estação chuvosa, há diferença estatística na incidência de folíolos com galhas entre C. sabulicola e C. depilis, estas duas espécies são afetadas diferentemente durante a estação chuvosa. De forma geral, a maioria dos morfotipos foi mais abundante na estação seca. Os galhadores de 18 morfotipos não foram determinados, porque as galhas coletadas apresentavam parasitóides ou estavam vazias. Os cecidomiídeos foram os responsáveis pela indução de cinco morfotipos. Os invertebrados associados às galhas pertencentes às ordens Hymenoptera, Diptera, Coleoptera e Acari. Os resultados obtidos neste estudo apontam que as três espécies de Copaifera possuem um número expressivo de galhas, porém menor que o relatado na literatura para C. langsdorffii, a qual é considerada uma super hospedeira.
