The following is virtually the author's abstract. At Auburn, Alabama, larvae of Hypera variabilis[Hypera postica] (Hbst.) (postica (Gylh.)) were found in lucerne fields during each month of the year in , but most abundantly from late March until mid-April. Larval activity was not influenced by time of day, but the adult weevils were much more active at night than during daylight. Alfalfa Weevil Hypera postica (Gyllenhal, ) (Coleoptera: Curculionidae) On three occasions, this destructive pest of alfalfa was accidentally introduced in North America. Alfalfa weevil has been the target of classical biological control efforts since its discovery in North America more than 90 years ago.
The introduced alfalfa weevil Hypera postica Gyllenhal (Coleoptera: Curculionidae) is among the most important alfalfa-feeding insects in the United States and Canada and occasionally causes great economic damage (Steffey & Armbrust ).

Common Name: Alfalfa weevil Scientific Name: Varies Order: Coleoptera Description: Adult beetle is a brown weevil, about to inches long, with a downward projecting beak and a wide darker stripe down the middle of the back.
The color may vary from almost uniform brown to nearly black. Larvae are legless, plump-bodied and yellowish when young turning to pale green as they get larger.
The alfalfa weevil (Hypera postica) is one of the primary insects that can defoliate alfalfa. It can be an important early-season pest of established alfalfa stands. New seedings are not typically affected. Alfalfa is the preferred host, but alfalfa weevil will also feed.
Alfalfa weevil, (Hypera postica), insect pest of the family Curculionidae (order Coleoptera) whose larvae damage crops, most often alfalfa and clover. Though originally from Asia, the alfalfa weevil was introduced from Europe into the United States in the early 20th century and is.
The alfalfa weevil, Hypera postica (Gyllenhal), is thought to have been introduced into North America on three separate occasions as three distinct strains: eastern, western, and Egyptian.
The western strain was first reported near Salt Lake City, UT, in (); the Egyptian strain near Yuma, AZ, in (Wehrle ); and the eastern strain from Maryland in (Poos and BissellWood. Abstract Alfalfa weevil, Hypera postica Gyllenhal, is an important pest in forage alfalfa worldwide, and especially so on the Northern Plains of North America.

Illinois Agricultural Experimental Station, Special Publication Hypera postica Gyllenhal. Alfalfa weevil is one of the two most-damaging insect pests of alfalfa in Pennsylvania (the other is potato leafhopper). It is an exotic species that likely evolved in Asia, but appears to have been introduced to the United States at least three times.
Chromosome karyotypes, chiasma frequencies, and Giemsa C-banding patterns were analyzed from eight weevil populations: three of the eastern strain (Beltsville, MD; State College, PA; and Washington Co., IL) and two of the western strain (Logan and St.

Hypera postica was first found in the United States near Salt Lake City, Utah, inprobably an accidental introduction from Europe (Titus,). The weevil was confined to 12 western states untilwhen it was detected in Maryland (Bissell, ).
From Maryland, it spread rapidly and is now found in the contiguous 48 states. To introduce genetic resistance against alfalfa weevil (Hypera postica), leaves and petiole explants of three commercial alfalfa genotypes, including Km, Kk and Syn were transformed with Agrobacterium tumefaciens strains GV, LBA and AGL All the Agrobacterium strains used harbored the recombinant binary vector pBI containing a synthetic cry3a gene under .The alfalfa weevil, Hypera postica (Gyllenhal, ), is a variable worldwide pest that heavily damages alfalfa fields and is widely distributed in Iran.
The lack of information about Iranian populations of has motivated us to examine immature life stages H. postica.
