Abstract
Green lacewing,
Chrysoperla carnea
(Stephens) is a major, cosmopolitan predator of different pests. This study surveyed
relative consumption of three diets: eggs of flour moth,
Anagasta kuehniella
(Zeller), artificial diet (consists of honey, yeast and
water), and semi artificial diet (consists of honey, essential amino acid, Hen’s yolk egg powder, extracting of flour moth’s body, A, D,
E and B vitamin groups, yeast and water), on developmental time (T), weight, longevity and mortality percentage of larvae and pupae
and fecundity, fertility and sex ratio of female. All experiments were conducted at 25±5
℃
, 60± 5% RH, and photoperiod of 16:8 (L:
D).Results showed significant differences (p<0.01) between diets in different parameters except for egg Incubation period and sex
ratio. The lowest developmental time (T) 29.79±1.57 (day) was belonged to semi artificial diet. Larvae and pupae longevity were
12.29±0.29, 8.08±0.39; 19.46±0.76, 3.77±0.74 and 10.07±0.3, 7.15±0.34 (days) in diets respectively. The lowest and highest
mortality percentage of larvae and pupae on semi artificial and artificial diets were 4%, 0%, 42% and 38% respectively. The highest
weights of larvae and pupae (3.68±0.25 and 9.46±0.16 mgr.) were observed on semi artificial diet. The fecundity and fertility rates
were 410.25±9.33, 150±4.02 and 470.25±9.8; 370.98±6.7, 94.5±3 and 383.83±4.6 (egg/female) respectively. According to these
results the semi artificial diet was the most accurate diet for mass rearing of predator.

Introduction
The green lacewings,
Chrysoperla carnea
(Stephens)
(Neuroptera: Chrysopidae) is a cosmopolitan predator
nested in a wide range of agricultural habitats. Earlier,
many authors such as DeBach and Hagen (1964),
Henry (1979; 1985 and 1992), and Brooks et al.,
(1994) have discussed about the role of this predator
in controlling agricultural insect pests. Today,
Approximately 85 companies produce up to 125
natural-enemy species in order to manage different
pests, which one of the most common is green
lacewings (van Lenteren, 2003). Augmentative
biological control methods are dependent upon the
production of large numbers of high quality natural
enemies with the lowest cost (Glenister and Hoffmann,
1998; Nordlund, 1998; Smith and Nordlund, 1999 and
2000). In this method, biocontrol agents producers
often culture natural enemies on their natural preys (or
hosts), which need to maintain on their host plants.
Certainly, maintaining of three trophic levels need
high labor costs and costs associated with operating
and maintaining separate spaces and equipment to
produce each trophic level. Thus, reducing some of
the rearing costs like eliminating live plants could be
an important commercial approach (De Clercq, 2004).
For this reason, many preys of predators like different
lepidopterans can be reared effectively on diets that
are devoid of any living plant material. Several
predatory preys can be produced simply on relatively
cheap foods. Recently, the egg stage of a few species
