The occurrence of the tachinid parasitoid Billaea rhynchophorae (Blanchard) on larvae of the palm weevil Rhynchophorus palmarum (L.) was evaluated in plantations of piassava palm (Attalea funifera Mart.) and African oil palm (Elaeis guineensis Jacquin), in southeastern Bahia, Brazil. The monthly percentages of parasitism were evaluated during 13 months,(More)
Phytomonas wilt or Hartrot is a fatal disease of palm (Arecaceae) species including Cocos nucifera (coconut) and is caused by a phloematic trypanosomatid, a promastigote parasite that inhabits phloem sieve elements of disease palms. In the present work, we described the morphology of the interaction between a phloematic trypanosomatid (Phytomonas staheli)(More)
This study aimed to evaluate if Parisoschoenus obesulus Casey only attacks naturally aborting coconuts and, consequently, is not a pest of young fruits of coconut tree. Aiming to test this hypothesis, inflorescences at diverse stages of physiological development were offered to individuals of P. obesulus. The results showed that only aborting fruits were(More)
The aim of this study was to evaluate the losses provoked by the moth Hyalospila ptychis (Dyar) on green-dwarf coconut trees at Una, State of Bahia, Brazil. Inflorescences of 100 trees were inspected monthly, from April 1997 to March 1998, in a 15 ha orchard. The number of coconuts per inflorescence, fruits damaged by H. ptychis, and fruit losses due to(More)
Field experiments showed that males of the seed-feeding, Neotropical wasp Bephratelloides pomorum are strongly attracted to females. That this attraction was semiochemically mediated was demonstrated by both the response of male antennae to the whole-body extract of females and by behavioral bioassays. In the field, males were captured in traps baited with(More)
