Within tree distribution of a gall-inducing Eurytoma (Hymenoptera, Eurytomidae) on Caryocar brasiliense (Caryocaraceae)

Morphological Patterns of a Hymenopteran Gall on the Leaflets of Caryocar brasiliense Camb. (Caryocaraceae)

Anatomical studies in the leaflet globoid galls of Caryocar brasiliense, the “pequi”, aimed to answer how oviposition and the feeding behavior of the galling herbivores altered the morphogenetical patterns of the host plant. C. brasiliense globoid gall was (1.28 ± 0.20) mm × (0.90 ± 0.25) mm, with hairy surface; it is sessile and projected to the abaxial surface. Young galls were red while the ...

Colleters in Caryocar brasiliense (Caryocaraceae) ontogenesis, ultrastructure and secretion.

Colleters are widely distributed and have been reported in several taxa. However, the only report of colleters in the Caryocaraceae family is in Caryocar brasiliense. This study purports to describe the distribution, structure and ultrastructure of colleters in C. brasiliense. Vegetative shoot apices with stipules in different stages of development were collected, fixed, and processed by light,...

Differential effects of land use on ant and herbivore insect communities associated with Caryocar brasiliense (Caryocaraceae).

Simplification of natural habitats leads to a modification of the community associated with a host plant. Pequi trees (Caryocar brasiliense) are common to find in central Brazil, especially in the middle of monocultures, such as soy, corn, pasturelands or Eucalyptus plantations. On this scenario we hypothesized that habitat modification differentially affects the diversity of ants and herbivore...

Strawberry Guava (Psidium cattleianum) – Prospects for Biological Control

Strawberry guava Psidium cattleianum Sabine (Myrtales, Myrtaceae) was introduced to Hawaii about 1825 and quickly escaped from cultivation. It is now found on all inhabited islands where it is one of the most important forest weeds. The small trees form extremely dense monotypic stands up to 10 m in height. Four insect species were found that have significant deleterious effects and, therefore,...
