Laboratory and field studies were conducted to determine parasitism of Nezara viridula in nine host plant communities in Alachua County, Florida. The influence of parasitism on N. viridula performance in soybean is described quantitatively. Rearing methods for N. viridula and Trichopoda pennipes were developed and parasitization of N. viridula adults by T. pennipes and eggs by Trissolcus basalis was characterized. In all host plant communities studied, during 1986 and 1987, N. viridula adults were consistently parasitized by T. pennipes, but nymphs (IV and V instars ) were only occasionally parasitized. Eggs were parasitized by T. basalis. Both parasite species were present in all host plant communities sampled. The N. viridula population did not reach threshold levels during both years in soybean and levels of parasitization were lower in soybean than in other host plant communities studied. Solenopsis invicta was the most common and important species of ant preying on N. viridula egg masses insoybeans. An average of 68.5% of egg masses were preyed upon during 48 hours of exposure in soybean. Trichopoda pennipes parasitization had a strong negative effect on N. viridula longevity, fecundity and feeding. In cages with parasitized N. viridula adults, 92.6% of seeds were normal compared with 78.2% for cages with unparasitized stink bugs. Trichopoda pennipes oviposits over the entire N. viridula adult body surface. There was no strong relationship between abundance of tachinid eggs on host body and level of parasitiza MenosLaboratory and field studies were conducted to determine parasitism of Nezara viridula in nine host plant communities in Alachua County, Florida.

Clonal propagation by tissue culture is useful to regenerate large populations of plants with similar characteristics. There are no previous reports of micropropagation of Cordia verbenacea. In this study, in vitro techniques were applied multiply this important Brazilian medicinal plant. Apical and nodal segments were cultured on Murashige and Skoog solid (0,6%) medium (MS) supplemented with 0.1, 1.0, 5.0 and 10.0 µM kinetin and 0.01µM naphthaleneacetic acid (NAA). Segments apical yielded more propagules than nodal segments. The number and length of propagules increased with in kinetin levels at 5 µM kinetin, decrease with more concentration. The treatment containing 5 µM kinetin and 0.01µM NAA yielded 2.7 propagules per explant. Propagules rooted on MS medium without growth regulators. Finally, 90-95% of the micropropagated plants survived when transferred to greenhouse conditions. |
