Abstract Developmental ability of Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae) was examined on six different sorghum milling fractions: Bran, Shorts, Cgrits, Fgrits, Red dogs, Flour, and also on a standard diet of Oat Flakes. For this purpose, a 1-day-old egg was placed in a vial containing 1 g of one of the sorghum fractions ...

Journal of Stored Products Research, 2021
Abstract The insect's response to various living substrates is an important determinant for their life history and demography reflected in their feeding and egg-laying preferences. However, research on polyphagous stored product insects such as the sawtoothed grain beetle, Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), are largely focused ...

Sawtoothed grain beetle (oryzaephilus surinamensis linnaeus) and human ecology
ПЕСТ-МЕНЕДЖМЕНТ, 2021Суринамский мукоед (Oryzaephilus surinamensis Linnaeus) широко распространен по всему миру. Это один из самых опасных вредителей сельскохозяйственной и пищевой продукции, кроме того, он представляет угрозу здоровью людей. Для борьбы с суринамским мукоедом предлагается применение инсектицидных средств и ионизирующего излучения.

Abstract 1. 1. The chitinolytic enzymes in a mycophagous insect, the foreign grain beetle, Ahasverus advena , and a non-mycophagous insect, the sawtoothed grain beetle, Oryzaephilus surinamensis , were measured. 2. 2. Larvae and adults of A. advena exhibit three-fold higher chitinase levels than do the same stages of O.

Two types of sense organs are present on the antennae of adult sawtoothed grain beetles, Oryzaephilus surinamensis. Sensilla chaetica are present on all the antennal segments and sensilla basiconica are present on the three segments which compose the antennal club.

Journal of Economic Entomology, 1990
Male and female sawtoothed grain beetles, Oryzaephilus surinamensis (L.), released on a flat arena were recaptured in corrugated cardboard traps baited with a mixture of the male-produced aggregation pheromones 3(Z),6(Z)-dodecadien-ll-olide, 3(Z),6(Z)-do-decadienolide, and 5(Z),8(Z)-tetradecadien-13-olide (cucujolides) or l-octen-3-ol, which is ...

Insecticidal control and genetic structure were studied in a strain of the saw-toothed grain beetle, Oryzaephilus surinamensis (L.), initially comprising 69.5% susceptible phenotypes. Populations were exposed for 20 wk to fabric treatments of pirimiphos-methyl in model grain bins under simulated field conditions, which included the presence of 16 ...

Relative retention of adult sawtoothed grain beetles in potential food baits
Postharvest Biology and Technology, 1992Abstract Retention of adult sawtoothed grain beetles, Oryzaephilus surinamensis (L.), in freshly cracked corn, wheat and sorghum; rolled oats or freshly cut kibbled carobs, was evaluated in the laboratory via choice tests. Retention in a food mixture (cracked corn, cracked wheat, rolled oats and kibbled carobs; 1:1:1:0.2 parts by weight), used for ...

Resistance of field strains of Oryzaephilus surinamensis L. (sawtoothed grain beetle) to grain protectants was assessed using commercial dose rates of protectant in treated grain bioassays. Grain protectants tested were: chlorpyrifos- methyl, 5 and 10 mg/kg grain; methacriphos, 10 and 18 mg/kg; pirimiphos-methyl 4 mg/kg; fenitrothion, 12 mg/kg, plus ...
