Basic Information

Larinus

Seedhead Weevils

Larinus is a genus of true weevils, comprising about 180 species, mostly in the Palaearctic region with some species introduced to North America. Turkey appears to have a significant diversity of the group, with more than 50 species recorded in the eastern part of the country. Several of these beetles are used as agents of biological pest control against noxious weeds. They feed on flower heads, destroying the developing seeds of the weeds.

Morphological Features

Mature larva: body length 8.50–13.00 mm, stocky, strongly curved. Head width 1.8–2.0 mm, oval, endocarinal line absent. Setae on head capsule and rostrum straight, distinctly shorter than setae on thoracic and abdominal segments. Frontal setae fs1–fs5 present, all of same length. Antenna with sensorium conical triangular, short, located medially. Labrum about 2 times as wide as long, with 3 pairs of hairform labial setae. Clypeus 3 times as wide as long with 2 pairs of short setae. Epipharynx with 5 pairs of blunt, finger-like anterolateral setae and 2 pairs of anteromedial setae. Mandible with 2 unequal dorsal setae. Maxilla: stipes with 1 stipal and 2 palpiferal setae; mala with 10 slightly curved dorsal setae and 4 short ventral setae. Postlabium heart-shaped, with 3 pairs of macro setae. Thoracic segments more pigmented than abdominal segments; dorsal parts densely covered with long, hairform, light brown setae. Abdominal segments I–III almost equal length, slightly smaller than IV–VI; spiracles close to anterior margin of segments I–VIII. Abdominal segment IX with 3 pairs of micro ventral setae and 2 pairs short, thin dorsal setae. Setae distinct, very long, hairform (apart from those on head capsule and rostrum) in different length.
