spread in new world but the genus
Linshcosteus was restricted to Indian subcontinent;
more recently a new species was also
reported in south India. Since they occupy
hidden dark habitats of the dry areas, adapting
peculiar risky collection and sampling techniques
with trained team was necessary to
monitor these insects. For studying their population
dynamics and life cycle, general collections
of assassin bugs at Kalugu Maydu close
to Nanguneri, Tamil Nadu state, south India
were carried out by night observation in three
occasions by a team of three persons. In November
2012 nine individuals and in May
2013 two individuals of Linshcosteus karupus
were collected at a single locality, an exfoliated
sedimentary rock formation area, approximately
10m high and 40m in length, situated
on an expanse of semi-arid scrub, sparsely
populated by xerophytic vegetation. In comparing
population of L.karupus since 1994 to
as of now their population was declined significantly
up to four to sixth fold (P=0.025;
t=- 2.979; df=4,1). The bugs captured from
deep fissures and crevices in the rock where
rodent, snakes and lizards were also hiding.
There population was in decreasing trend in
the area due to habitat disturbance in the form
of noise pollution by mining as well as invading
agricultural practises. The collected insects
were brought to Gorakhpur and being reared
in the laboratory for studying their life cycle
and behaviour providing Guinea pig blood
meal. Moreover, individuals of insectivorous
assassin bugs such as, Acanthispis pedestris
Stål, Rhynocoris fuscipes (F.) and
Rhaphidosoma atkinsoni Bergroth were also
collected in the same locality during the dusk
for observing their predatory efficiency against
agriculture insect pests.
