A Generic Review Of The Acanthaclisine Antlions Based On Larvae (Neuroptera: Myrmeleontidae), Lionel Stange, Robert B. Miller
A Generic Review Of The Acanthaclisine Antlions Based On Larvae (Neuroptera: Myrmeleontidae), Lionel Stange, Robert B. Miller
Insecta Mundi
The tribe Acanthaclisini Navas contains 14 described genera which we recognize as valid. We have reared larvae of 8 of these (Acanthaclisis Rambur, Centroclisis Navas, Fadrina Navas, Paranthaclisis Banks, Phanoclisis Banks, Synclisis Navas, Syngenes Kolbe, and Vella Navas). In addition, we have studied preserved larvae from Australia which probably represent the genus Heoclisis Navas. This represents the majority of the taxa, lacking only the small genera Avia Navas, Cosina Navas, Madrasta Navas, Mestressa Navas, and Stiphroneuria Gerstaecker. Studies of these larvae have revealed structural differences, especially of the mandible, which we have employed to provide identification of these genera by …

West Indies Brenthia (Lepidoptera: Choreutidae), J. B. Heppner
Insecta Mundi
The genus Brenthia includes numerous species in the New World and another large contingent in the tropical parts of Asia and Australia. There also are a few species known from Africa (Heppner, 1981). The few species in Japan represent the only intrusion of the genus into the Palearctic region.
Modification Of Sand Fly Biting Behavior By Leishmania Leads To Increased Parasite Transmission, Raymond Beach, Gabriel Kjilu, Johannis Leeuwenberg
Modification Of Sand Fly Biting Behavior By Leishmania Leads To Increased Parasite Transmission, Raymond Beach, Gabriel Kjilu, Johannis Leeuwenberg
Harold W. Manter Laboratory: Library Materials
To attempt rodent-sand fly-rodent transmission of Leishmania major, laboratory-reared Phlebotomus doboscqi were fed on L. major-infected mice and then refed on uninfected mice 21 days later. Flies which refed either probed 1–2 times and took a full blood meal in less than 10 minutes or probed 3 or more times and took little or no blood during a period of 15 minutes or more. When dissected, 7 of 8 flies which experienced difficulty in obtaining a blood meal had flagellates in their cibaria, an observation supporting the hypothesis that parasites in this part of the alimentary canal modify normal …
Response Of An Irrigated Cool- And Warm- Season Grass Mixture To Nitrogen And Harvest Scheme, Joseph L. Petersen, Lowell E. Moser
Response Of An Irrigated Cool- And Warm- Season Grass Mixture To Nitrogen And Harvest Scheme, Joseph L. Petersen, Lowell E. Moser
Department of Agronomy and Horticulture: Faculty Publications
Maintaining a mixture of cool-and warm-season grasses under intensive management for season-long production is difficult, due to species shifts, especially to a dominance of cool-season grasses when heavy amounts of nitrogen(N) fertilizer are used. The objective of this study was to determine if high forage yields could be produced season long while maintaining a desirable balance of warm-and cool-season grasses.
The study was conducted near Mead, Nebraska on a Sharpsburg silty clay loam (Typic Argiudoll). An irrigated mixture of 3 warmseason grasses and 1 cool-season grass, big bluestem (Andropogon gerardii Vitman), switchgrass (Panicum virgatum L.), and indiangrass [ …
