Many insects are known to give response in adaptive way for seasonal changes in day lengths. Photoperiod control's many developmental responses and allows insects to survive periods of unfavorable environmental conditions. An experiment was conducted to study the effect of different photoperiod lengths on biological parameters of green lacewing, Chrysoperla carnea. Four different photoperiod regimes were selected with varying lengths of light/dark hours (8/16, 10/14, 24/0 and 0/24) at a… 
Effects of photoperiod on development and demographic parameters of the predatory thrips Scolothrips longicornis fed on Tetranychus urticae.
The consequences of the present research demonstrated that a 12:12 L:D photoperiod is the most favorable for the reproduction and development of S. longicornis and that for mas rearing for augmentative biological control programs, would be the ideal Photoperiod to maximize production.
Day length constrains the time budget of aphid predators
It is shown that day length affects development and predation, but that the direction depends on species, and differences in the use of day length may alter the efficiency of biocontrol agents in a changing climate.


Effect of Photoperiod on the Life History of the Predatory Bug, Macrolophus Caliginosus Wagner [Hemiptera:Miridae]
Light was of significance for the development of the predator embryos during incubation period, but hatching was reduced at 8L:16D in comparison to hatching at 16L:8D, and the number of T. vaporariorum eggs consumed by the predator increased with decreasing photoperiod.
Storage of the mass-produced predator Chrysoperla carnea (Neuroptera: Chrysopidae): influence of photoperiod, temperature, and diet
High survival and excellent poststorage reproduction occurred when the animals received a high carbohydrate diet before storage and a carbohydrate and protein diet during and after storage.
Production of the green lacewing Chrysoperla caranea (Steph.) (Neuropt., Chrysopidae) reared on semi‐artificial diet based on the algae, Chlorella vulgaris
Normal adult longevity and egg deposition were obtained after the addition of the carbohydrates, salts and vitamins that were necessary to the larvae to complete their development to reach the pupal and adult stages.
Effects of three aphid species (Homoptera: Aphididae) on development, survival and predation of Chrysoperla carnea (Neuroptera: Chrysopidae)
The effects of three aphid species (fourth instars only), Aphis gossypii Glover; Myzus persicae (Sulzer) and Lipaphis erysimi (Kaltenbach), on immature development, survival and predation of the
Insect Photoperiodism and Circadian Clocks: Models and Mechanisms
Different ways in which identified molecular components of the circadian pacemaker may play a role in photoperiodism are explored, particularly as further output components are identified.
Rearing Lacewings, Chrysoperla carnea and Chrysopa oculata (Neuroptera: Chrysopidae), on prepupae of Alfalfa Leafcutting Bee, Megachile rotundata (Hymenoptera: Megachilidae)
Lacewings are an important group of insect biological control agents. Protocols for rearing lacewings often require rearing of an additional insect species to be used as a diet, and this can be
Evaluation of predatory efficiency of Chrysoperla carnea (Stephens) reared on artificial diet against tobacco aphid, Myzus persicae (Sulzer) in comparison with other predators
It was found that C. camea reared on artificial diet was effective in suppressing the aphid population and was comparable with other predators.
Commercialization of Predators: Recent Lessons from Green Lacewings (Neuroptera: Chrysopidae: Chrosoperla)
This paper aims to demonstrate the effectiveness, ecological benefits, and safety of biological control under commercial conditions, and the cost of mass-rearing and manipulating natural enemies and their increased use in pest management.

Mass Rearing a Green Lacewing
Improved procedures for rearing Chrysopa carnea Stephens were developed. Use of a paper Hexcel® in fabricating a larval rearing unit provided an inexpensive method of isolating larvae in individual
