The study also showed that insecticide use did not affect pest entrapment by sticky glandular trichomes
. Plants treated with imidacloprid, a common tobacco insecticide, had fewer spined stilt bugs than untreated plants, but that did not significantly affect pest densities or plant health.
Recently we described the natural history and the resin-collecting behavior of the assassin bug Heniartes stali Wygodzinsky 1953 (Hemiptera: Reduviidae: Harpactorinae) in association with Rubus adenotrichos (Schltdl.) (Rosaceae), an Andean wild blackberry whose stems and buds are covered by a densely arranged glandular sticky trichomes
. We collected immature and adults of both sexes of H.
All genotypes analyzed in this study present glabrous adaxial surface, and trichomes
have a very low density on the abaxial surface, thus explaining the presence of this species in the culture.
The quantification of glandular trichomes
(types I, IV, VI and VII) in leaflets was done according to Glas et al.
In paradermal sections, the density (number of analyzed structures/area) and relative frequency (number of structures analyzed/total epidermal cells) of trichomes
scars and stomata were quantitatively examined (n = 30).
The stem indumentum presents glandular and non-glandular trichomes
One-celled simple eglandular trichomes
and rarely one-celled hook-shaped eglandular trichomes
are seen on the epidermis.
Like the more dorsal TAPs, the vTAPs are associated with trichomes
and occur in a consistent location, inferior to the dorsal seta known as S2 (Ramin et al.
Micromorphological studies of trichomes
of Lamiaceae revealed that different types of glandular and nonglandular trichomes
occur in the family .
are generally multicellular and long (Figure 4).
