Conteúdo: |
Eggs of Trichopoda pennipes were found on Nezara viridula host bodies at all sample sites. Supernumerary oviposition was found to be common on both male and female, and males had a higher incidence of tachinid eggs and more eggs/individual. Males consistently had higher parasitization levels. Tachinid eggs were found virtually on the whole body surface of Nezara viridula. The highest concentration was on the thorax, followed by the abdomen and head. The largest number was laid on the ventral surface of the thorax, while very few on the appendages. A significant relationship between number of tachinid eggs on the host body and level of parasitization was found. More tachinid eggs per host were directly related to a higher probability of parasitization for individuals with three eggs or less. When two tachinid eggs were present on a host, only 0.95 were truly parasitized With three eggs or more, 0.99 were truly parasitized, and larger number of tachinid eggs on the host does not improve chances for being parasitized. |
