“…The shorter life span of males, in rooms where the CO 2 concentration reached 4,425 ppm, indicates that males have greater sensitivity to the conditions of CO 2 during the immature stages, and that is not possible to make such assessment in females, because they die soon after they oviposit. The results described are different from those reported by Edwards and Patton (1965) who observed that anesthesia with CO 2 concentrations above 600,000 ppm, even when the O 2 concentration is maintained similar to atmospheric conditions (210,000 ppm), has deleterious effects on size, weight and growth of nymphs of Acheta domesticus (Linnaeus, 1758). The authors also reported that the heartbeat of insects decreased with the increase of CO 2 concentration.…”

Eggs of Anagasta kuehniella (Zeller 1879) are widely used for mass rearing ofAnagasta kuehniella (Zeller 1879) are widely used for mass rearing of Anagasta kuehniella Trichogramma spp. and other Trichogramma spp. and other Trichogramma parasitoids and predators, largely commercialized in many countries. The aim of this study is to evaluate the effect of carbon dioxide (CO 2 ) originated from larval metabolism on the biological parameters of A. kuehniella. For that purpose, we assess the production of carbon dioxide (CO 2 ) per rearing tray of A. kuehniella and the A. kuehniella and the A. kuehniella effect of CO 2 on the viability of egg-to-adult period and oviposition of A. kuehniella. Results allow to estimate that a rearing tray, containing 10,000 larvae between the 4 th and 5 th and 5 th th instars, produces an average of 30.67 mL th instars, produces an average of 30.67 mL th of CO 2 per hour. The highest egg production of A. kuehniella was obtained when the larvae were kept in rooms A. kuehniella was obtained when the larvae were kept in rooms A. kuehniella with lower concentration of CO 2 (1,200 parts per million -ppm), producing 23% more eggs than in rooms with higher CO 2 concentrations. In rooms with high density of trays (70 trays/room), CO 2 concentration exceeded 4,400 ppm. The viability of the egg-to-adult period was not infl uenced by carbon dioxide.

“…Trudgill et al (2005) noted that possibly in high temperatures the rate of differentiation increases and development tends to increase proportionally faster than the growth rate, with the result that less time is available for resource capture. According to Daumal and Boinel (1994), exposure of Þfth-instar larvae of A. kuehniella to a temperature of 10ЊC resulted in heavier adults (males and females) and more fertile females. The …”

“…According to Trudgill et al (2005), temperature is a basic factor that inßuences the course of life, especially for poikilothermic species, given that temperature regulates the development of all stages of an insect. An unsuitable temperature will compromise the insectÕs reproductive capacity; for instance, high temperatures (above 27.5ЊC) during the larval phase can cause the sterility of adult males of A. kuehniella (Siddiqui and Barlow 1973), and rearing in cold temperatures (10ЊC) can also cause sterility in the male moth (Daumal andBoinel 1994, Ayvaz andKarabö rklü 2008). High temperatures also favor the emergence of the larval parasitoid Habrobracon hebetor (Say), which is attracted by the frass produced by the larvae (Parra et al 1996).…”

Eggs of Anagasta kuehniella (Zeller) are widely used in mass rearing of parasitoids, especially Trichogramma spp. and predators in many biological-control programs. The objective of this study was to improve the efficiency of mass rearing of A. kuehniella through determining the optimal temperature conditions for rearing, by assessing the effect of temperature during the developmental stages on the reproduction of A. kuehniella. We evaluated 1) the effect of temperature at which A. kuehniella was kept from egg to adult death, on reproduction; 2) the effect of temperature during the larval and pupal stages on oviposition; and 3) the effect of different temperatures on adults that originated from larvae kept in a constant temperature of 25°C. The results indicated that the optimal temperature range for the development of A. kuehniella is between 20-30°C, as at 30°C there was a marked decrease in viability of the egg and larval stages. The best temperature for maintaining A. kuehniella from egg to adult death is 25°C. Temperatures of 30 and 32°C lead to deformations in genitalia of males, reducing the viability of eggs, and also eggs and females from these temperatures have lower weights. The rearing temperature of immatures affects the egg-laying capacity of adults and the egg viability. The oviposition capacity of adults kept in different temperatures ranging from 18 to 32°C, after being reared in constant temperature (25°C) during the larval stages, was not affected.

“…The higher posture capacity may be a reflection of the pupal weight, since pupae (female) from larvae fed the artificial diet were nearly 20 mg heavier than larvae fed the natural diet (F = 70.9; df = 1; P = 0.001) (Table III). Daumal and Boinel (1994) found a direct relationship between the weight of insects and their fertility.…”

The Brazilian Poplar Moth, Condylorrhiza vestigialis (Guenée), compromises the wood productivity of poplar trees (Populus sp.), mainly affecting the matchstick industry in southern Brazil. Considering the lack of information on rearing techniques for this insect, the objective of this study was to develop an artificial diet to rear C. vestigialis with biological characteristics similar to the wild insects. A properly diet will enable bio-ecological studies and biological control programs using the baculovirus Condylorrhiza vestigialis multiple nucleopolyhedrovirus (CvMNPV). To attain this objective, first, three artificial diets were tested. Only the diet based on corn, wheat germ and yeast as a protein source (Diet 3) was able to supply the nutritional requirements of the moth and support completion of its life cycle. In the second experiment, Diet 3 was compared to the natural diet of C. vestigialis. The artificial diet supported a viability of 81% of the eggs, while only 40% developed on the natural diet. Life-table data showed the same pattern: the net reproductive rate (Ro) of C. vestigialis reared on the artificial diet was 401.70, and on the natural diet was 151.22. The artificial diet is adequate for mass rearing of C. vestigialis, to support biological control programs using the baculovirus.
