Gas chromatographic-electroantennographic detection (G3C-EAD) experiments showed that antennae of males and females of the goldeneyed lacewing, Chrysopa oculata Say (Co. = Chrysopa), consistently responded to four compounds extracted from the abdominal cuticle of males:nonanal, nonanol, nonanoic acid, and (1R*,2S*,5R*,8R*)-iridodial.

Thermal Requirements for Development in Chrysopa Oculata: A Geographically Stable Trait
Ecology, 1987Chrysopa oculata from five widespread localities (southern Canada to montane Mexico), exhibited remarkable similarities in their thermal requirements for nondiapause development. Lower thermal thresholds (t) varied by only 1.2°C., and the degree—days required for total preimaginal development (K) differed among the populations by °85°d.

Diapause in the neuropteran Chrysopa oculata
Journal of Insect Physiology, 1969Abstract Chrysopa oculata has a facultative diapause in the third instar within the cocoon. At 24 ± 1°C diapause was induced when both second and third instars experienced short-day (LD 12:12), whereas continuous development was promoted when either of these two stages experienced long-day (LD 16:8).

Immature development of the common green lacewing, Chrysoperla (= Chrysopa ) carnea Stephens, requires 20.5, 21.6, and 24.9 d at 27°C, with a photoperiod of 16:8 (L:D), when fed Ostrinia nubilalis (Hubner) (European corn borer) eggs, Agrotis ipsilon Hufnagel (black cutworm) eggs, and A. ipsilon neonates, respectively.

Abstract Dormancy in Chrysopa oculata, a multivoltine species, is controlled by reponses to photoperiod and temperature. Variation in both the critical photoperiod for diapause induction and the duration of diapause is positively related to the latitudianl origin of the population.

1R,2S,5R,8R; 1R,2S,5R,8S; 1S,2S,5R,8R; and 1S,2S,5R,8S-Iridodials have been prepared in five steps from 4aS,7S,7aR and 4aS,7S,7aS-nepetalactones, major components of catnip oil. 1R,2S,5R,8R-Iridodial has been identified as a male-produced male-aggregation pheromone for Chrysopa oculata, the first pheromone of any kind identified for lacewings.

DIETARY REQUIREMENTS FOR MATING INCHRYSOPA OCULATA(NEUROPTERA: CHRYSOPIDAE)
The Canadian Entomologist, 1973AbstractThe reproductive behaviour ofChrysopa oculataSay females shows a high degree of dependence on diet. Females remain unmated when maintained on a regimen of sugar and water, whereas they mate and produce fertile eggs when given pea aphids prior to pairing. In contrast, the males do not require a diet other than sugar and water in order to produce

Methyl salicylate is a field attractant for the goldeneyed lacewing,Chrysopa oculata
Biocontrol Science and Technology, 2006Abstract The green lacewing, Chrysopa oculata Say, was significantly attracted to sticky cards baited with undiluted methyl salicylate (MeSA) in an unsprayed vineyard in Washington State. During the first three weeks of the five week experiment 5–8 times as many C. oculata were trapped on MeSA-baited as on unbaited or hexane-baited cards. Diluted (10%,

Toxicity of Pesticides toChrysopa oculataSay (Neuroptera: Chrysopidae)
Journal of Economic Entomology, 1985The susceptibility of first instars and adults of Chrysopa oculata Say to pesticides used in tree fruit production in Ontario was assessed. Most organophosphorous insecticides except phosalone were toxic to both stages. The synthetic pyrethroids, with the exception of fenvalerate and flucythrinate, were generally more toxic than organophosphorous ...

Environmental Entomology
Abstract The green lacewing Chrysopa oculata Say is a crucial natural enemy contributing to arthropod pest management in crop production. Chrysopa spp. are unique because both larvae and adults are predatory. In contrast, only the larvae of Chrysoperla spp. are predatory, and their adults consume nectar and pollen.
