2016) study was confined to the shape of the third segment and the structure of the AD, but it left unexamined the fourth segment, which contains a multitude of sensilla
that play a key role in locating the settlement site (Walker et al.
3 times as long as preceding somite, tapering posteriorly; with naked rounded anal operculum; the two sensilla
associated to the anal operculum separated by a gap about as wide as the width of the anal operculum, and displaced medially.
The researchers observed that bees that had previously been more social but were now more solitary had reduced numbers of sensilla
, suggesting that because their behaviors required less sensory energy to be expended, their physical bodies responded by making their antennae less complex.
First exopodal segment with pectinate membrane at base of small, outer naked spine and serrations and several sensilla
along outer margin.
The occurrence of apical labial sensilla
in the Aleyrodidae and evidence for a contact chemosensory function.
The purpose of this study was, in part, to describe general larval morphology with an emphasis on sensilla
of legs and urogomphi of an Oklahoma population of N.
A pair of cervical ventral sensilla
usually present, but if absent then with a patch of anterior katepisternal setae; antennal ascoids usually simple, at most with a proximal protuberance; male flagellomere 1 usually with the external ascoid apically implanted in relation to the internal ascoid; other characteristics variable .

on newly hatched larvae of Gasterophilus intestinalis and Oestrus ovis" Medical and Veterinary Entomology, vol.
Some of these sensilla
(rheo, chemo-, photo- and mechanoreceptors) could possibly be used for host finding [4,32,36,37] particularly touch receptors, since the fluke depends on it in locating and maintaining contact with the host.
5 x length of gonocoxite; gonostyle basally with a cluster of lateral setae, with scattered spiniform sensilla
along length; gonocoxal condyles triangular in dorsal and ventral views; aedeagus asymmetrical; basiphallus broad in dorsal view, connected laterally to parameres by parameral-aedeagal membrane, medially to distiphallus, morphodorsally with pointed connection to ventral epandrial plate; distiphallus comprised of two lateral phallomeres and morphodorsal phallic membrane forming duct; distiphallus twisted 90[degrees] to the left; parameres triangular with a morphoventral projection carrying small, verruca-like rugae; epandrium (Fig.
Considering this, we are of the opinion that aggregation behavioural response may depend on the density of bedbugs, number of sensilla
on the antenna (23, 29-30), olfactory receptors neurons responding (22, 24).
Apex of third palpomere with 2-5 sensilla
, longest 16 pm long.
