Hemiptera en casa

Arias, B. Barreto, N; E.

ISSN Pine-oak forests of Chiapas have been exposed for centuries to a low magnitude but high frequency of human disturbance regime, resulting in a fragmented forest landscapes that probably have impact on structure and composition of insect communities. In this study the community of Heteroptera was described in 3 secondary forest of pine-oak with different historical disturbance regimen. The insects were sampled with sweep net at 18 plots, and the Hill numbers were calculated as estimators of Heteroptera diversity. At each plot was recorded the presence of extraction of soil, wood, firewood, and solid waste. We grouped the insect by size and trophic class, as an approximation to functionality of Heteroptera community.

Herbivore natural enemies base their foraging decision on information cues from different trophic levels but mainly from plant odors. However, the second trophic level i. We have evaluated the role of the aggregation pheromone from Frankliniella occidentalis Pergande as a potential kairomone for its natural enemy, the predatory bug Orius laevigatus Fieber. For this purpose, we have analyzed the response of O. These compounds have been offered to O. None of the compounds attracted adults or nymphs when they were individually supplied. Conversely, they were significantly attracted to both adults and nymphs when offered as a blend. A These results suggest that specific blends of these compounds from the aggregation pheromone may be used as an attractant to O. The results of this work highlight the importance of studying olfactory responses of natural enemies for a better understanding of their foraging behavior. Potential uses of these results in future studies are discussed.

Hemiptera en casa

The hemiptera are divided into four smaller groups based on their physical features. These groups include aphids, mealybugs, and scale insects; cicadas and hoppers; moss bugs; and true bugs. The relationships of whiteflies are uncertain, and they are sometimes included with aphids or hoppers. Hemipterans are extremely variable in form, ranging from long, slender, and sticklike, to short and round, to very flat. The bodies of female scale insects are completely covered by a waxy shield.
