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.

The invasive tree Melaleuca quinquenervia (Cavanilles) Blake (Myrtaceae) is widely distributed throughout peninsular Florida, U.S.A. and poses a threat to species diversity in the wetland systems of the Florida Everglades. Biological control research targeting the weed resulted in the introduction of Oxyops vitiosa Pascoe, 1870 to Florida. Approximately three years following its release, adult weevils were collected over 12 consecutive months across six study sites, resulting in a 52:48 F:M sex ratio that did not vary among sites or over time. All female weevils were dissected and their reproductive anatomy was investigated, particularly in relation to the fluctuation of host plant suitability. The continuum of reproductive development was divided into three distinct stages: nulliparous, parous, or degenerative. The general anatomy of each stage is described. In contrast to other systems, fat body abundance provided little insight into the weevil's reproductive status, as 99.5% of all females possessed fat bodies that filled >2/3 of the abdominal cavity. Nulliparous weevils possessed the softest elytra and were lighter in color, parous weevils had the hardest and darkest elytra, while females with degenerative reproductive systems were intermediate to the other two reproductive classes. The proportion of parous O. vitiosa females in a population was strongly influenced by resource availability, as the number of actively ovipositing females increased concomitantly with increasing suitable foliage in the host's canopy.

Ctenatheta pasniki Lee & Ahn sp. nov. is described and illustrated in Korea. A description, habitus photograph, illustrations of the diagnostic characters of the new species, and a key to species of Ctenatheta are provided.

Distributional information is presented for Megaderus bifasciatusDupont, 1836, a rare species of longhorned beetle in the cerambycid tribe Trachyderini. Valid occurrence records from Mexico and Central America are listed, and enigmatic historical records for the southwestern United States are examined to attempt to determine their veracity. An inventory of specimens found in museum collections is documented. The records for Texas and Arizona are examined, and the likelihood that the species is, or ever was, present in the United States is discussed.

The Afrotropical-Australian-Indomalayan genus ConochironomusFreeman, 1961 is here recorded for the first time from China, with the description of Conochironomus jatsp. nov. based on an adult male collected from Hainan Province and redescription of C. nuengthaiCranston, 2016 based on associated material collected from Guangdong Province. Three unassociated pupal exuviae collected from Yunnan and Hainan Provinces are also described. In addition, keys to adult males and pupae of Indomalayan Conochironomus are provided.
