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.

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).

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.

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.

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.

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 ...

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

Abstract Field-collected female goldeneyed lacewing (Chrysopa oculata) strongly avoided ovipositing on substrates exposed over 24 h to three of four lady beetle species tested, resulting in circa 3-fold higher egg deposition on control versus coccinellid-exposed substrates.
