SEASONAL ABUNDANCE OF A PUPAL PARASITOID , DIAPETIMORPHA INTROITA ( HYMENOPTERA : ICHNEUMONIDAE )
TLDR
Seasonal abundance of a pupal parasitoid Diapetimorpha introita and the beet armyworm Spodoptera exigua was monitored with pheromone-traps and represents the most convenient time during which to conduct trapping experiments.
CYTOLOGICAL ATTRIBUTES OF SPERM BUNDLES UNIQUE TO F 1 PROGENY OF IRRADIATED MALE LEPIDOPTERA : RELEVANCE TO STERILE INSECT TECHNIQUE PROGRAMS
TLDR
Observations on 6 pest species in 5 families of Lepidoptera indicate that F 1 males (sterile) from irradiated fathers can be distinguished from fertile males by the nuclei cluster in the eupyrene sperm bundles.
Germanium-on-silicon waveguides operating at mid-infrared wavelengths up to 8 . 5 μ
We report transmission measurements of germanium on silicon waveguides in the 7.5-8.5 μm wavelength range, with a minimum propagation loss of 2.5 dB/cm at 7.575 μm. However, we find an unexpected
FECUNDITY AND LONGEVITY OF DIAPETIMORPHA INTROITA ( CRESSON ) ( HYMENOPTERA : ICHNEUMONIDAE ) REARED ON ARTIFICIAL DIETS : EFFECTS OF A LIPID EXTRACT FROM HOST PUPAE AND CULTURE MEDIA CONDITIONED
TLDR
Total egg production by D. introita was improved on artificial diet supplemented with lipids from the natural host but was not increased by the addition of materials produced by an ovarial cell line derived from S. frugiperda, which should focus on increasing fecundity of wasps reared on the artificial diet.

CW demonstration of SHG spectral narrowing in a PPLN waveguide generating 2.5 W at 780 nm
Periodically poled lithium niobate (PPLN) waveguides are a proven and popular means for efficient wavelength conversion. However, conventional PPLN waveguides typically have small mode field
Inherited sterility in Cactoblastis 537 INHERITED STERILITY IN CACTOBLASTIS CACTORUM ( LEPIDOPTERA : PYRALIDAE )
Newly emerged male and female adult cactus moths, Cactoblastis cactorum (Berg), were treated with increasing doses of gamma radiation, and the moths were outcrossed to fertile counterparts. Fecundity
DEVELOPMENT OF THE MOST EFFECTIVE TRAP TO MONITOR THE PRESENCE OF THE CACTUS MOTH CACTOBLASTIS CACTORUM (LEPIDOPTERA: PYRALIDAE)
Various trap specifications were evaluated to identify the most effective trap for capturing wild male Cactoblastis cactorum (Berg). All traps were baited with virgin female C. cactorum and, except
Quantifying skin photodamage with spatial frequency domain imaging : statistical results
We investigated the change in optical properties and vascular parameters to characterize skin tissue from mild photodamage to actinic keratosis (AK) with comparison to a published photodamage scale.
INFLUENCE OF HERBIVORE-DAMAGED CORN AND COTTON IN THE FIELD RECRUITMENT OF BRACONID PARASITOIDS FROM FERAL POPULATIONS
The potential to increase parasitism by Cotesia marginiventris through response to chemical signals emitted by herbivore-damaged plants was investigated in corn and cotton field plots. Recruitment of
