Historically, Psocoptera research has been lacking in agricultural field studies. This study is the first in California (U.S.A.) to survey almond and pistachio orchards for Psocoptera. The seven species we observed in orchards are the first host association records of psocids (Lachesilla pacifica Chapman, 1930, Lachesilla pedicularia (Linnaeus, 1758), Lachesilla rena Sommerman, 1946, Ectopsocus vachoni Badonnel, 1945, Ectopsocus californicus (Banks, 1903), Liposcelis bostrychophila Badonnel, 1931, and Liposcelis silvarum (Kolbe, 1888)) in two suborders (Psocomorpha and Troctomorpha) from California almond and pistachio orchards. The results of these observations also revealed a new California state record of L. silvarum. Implications of these findings are discussed.
