Ostrinia furnacalis is a corn stem-borer that develops complete metamorphosis and all stages in life cycle in corn. This research was aimed to examine several biology aspects of O. furnacalis such as life cycle, egg incubaton period, egg fertility, female fecundity, longevity of imago, and copulation time on artificial diet, based on the previous study. The results of the observations showed that the life cycle of artificial-diet-given O. furnacalis was between 27-34 days range. Female fecundity was 16-452 eggs with fertility rate of 61,97% and 3-5 days renge of egg incubation period. Longevity of imago was between 6-11 days range, and the longevity was longer in female compared to the male. The imago of O. furnacalis copulate on 0-3 days after emerge from pupae and the highest number in on the day 1. Copulation time was occurred at 3-8 hour after scotophase commenced and the highest was at third hour. The artificial diet used in this research can be used for O. furnacalis mass rearing purpose and performed shorter length of egg stage until pupal stage compared to mass rearing with natural diet.

Abstract. Mass production of lacewings is still a bottleneck for applied biological control and for biofactories producing natural enemies, due to the difficulties of large-scale production and the cost of the undertaking and the production of their alternative prey. Thus, the objective of this work was to evaluate the viability of an alternative artificial diet to rearing of Ceraeochrysa cincta (Schneider, 1851) (Neuroptera: Chrysopidae). Three treatments were analyzed for this purpose, consisting of: 1) natural diet - eggs of Corcyra cephalonica (Stainton, 1866) (Lepidoptera: Pyralidae), 2) artificial diet honey + beer yeast (1:1) and 3) natural diet (1) + artificial diet (2), and were offered to the larval stage of the predator. The biological parameters of C. cincta evaluated where: duration of larval, pupal and adult phases; pupal weight; pupal viability; sex ratio; pre-oviposition and oviposition periods and number of eggs per female. Were obtained adults only in the treatments 1 and 3 and, in the treatment 2 no insect reached the pupal stage. The results obtained demonstrated that the artificial diet, when offered in isolation, causes significant differences in the duration of the larval period, especially in the 3rd instar, and in the weight of the pupae, with the other similar parameters in the treatments, but can serve as a nutritional supplement.

The effects of foods on the life cycle, survival rate, and reproductive ability of Ostrinia furnacalis (Guenee, 1854) were studied in laboratory. Maize HN88-Fed O. furnacalis had a complete life cycle of 32.9 ± 1.7 days, which was 38.4 ± 1.5 days shorter than those fed with maize LVN4. The average survival rates of O. furnacalis on two types of feeds were 97.5% and 94.4%, respectively. When O. furnacalis were fed with 100% honey or 50% sugar or water, the average length of female life cycle as well as their everage laid egg number were 11.1 ± 0.9 days and 535.2 ± 77.2 eggs/female; 9.9 ± 0.8 days and 371.7 ± 47.4 eggs/female; 7.3 ± 0.6 days and 216 ± 32.6 eggs/female, respectively.

Abstract The melon fly, Zeugodacus cucurbitae (Coquillett), is a serious pest of many fruits and vegetables throughout the world. Here we have developed an easy and quick-to-prepare solid medium with multiple benefits including reductions in post-rearing waste, storage space, and labor for rearing Z. cucurbitae larvae. The development time from egg to pupa was 19.11 d when larvae were reared on the artificial diet, slightly longer than 17.73 d on pumpkin and 17.13 d on cucumber. Zeugodacus cucurbitae achieved higher values of pupal weight, length, and width on the artificial diet than two natural diet controls. The rates of pupation and adult emergence of Z. cucurbitae grown on the solid medium were comparable with those on pumpkin and cucumber. Furthermore, determined by age-specific two-sex life table method, the age-specific survival rate of Z. cucurbitae was higher on the artificial diet than cucumber but lower than pumpkin. The reproductive ability and population dynamics of Z. cucurbitae were not significantly affected on the solid medium compared with those on the two natural diets. The results suggest that our solid artificial diet is excellent for rearing Z. cucurbitae larvae in laboratory and may be used for its mass rearing, therefore facilitating its research and control.

ABSTRACT Coffee Berry Borer (Hypothenemus hampei Ferr.) Is the main pest in coffee plants in Indonesia. Characteristics of coffee berries that are attacked by pests, there is a small hole in the coffee berry and powder around it. Control is carried out biologically, technically, and chemically. These control techniques need to be tested for effectiveness in the laboratory. The test requires the insect H. hampei as a test insect. H. hampei can be obtained by mass propagation. Mass propagation can be done using artificial diet. This study was conducted to determine the effect of artificial diet on the life cycle of H. hampei. This study uses descriptive methods on 2 types of feed treatment; natural diet of coffee berry and artificial diet made from wheat powder and coffee powder. The results showed that the number of eggs produced by H. hampei in natural diet treatment could range from 30 to 46 eggs and every 3 days observation could lay eggs from 0 to 22 eggs. The percentage of eggs that succeeded in being imago was 95.32% with a sex ratio of 1: 10. The duration of life of H. hampei ranged from 100 to 150 days, with a period of 5-6 days, larvae 18-19 days and pupae 4-5 days. In the artificial diet, the egg method is able to grow into a second instar larval stage with a life span of 19 days.

As an important pest, Tetranychus urticae fed on thousands of host plants and showed strong capability in host adaptation. However, hardly any success artificial diet has been developed for it. In this study, we compared adult longevity and reproduction of T. urticae that fed on its natural food (bean leaves) and an artificial diet with leaf extracts added, and tried to investigate the reason why the artificial diet was inefficient through transcriptome analyses. Mean adult longevity and cumulative fecundities of T. urticae was reduced by 53.4% and 93.8%, respectively. Transcriptome analyses showed that 1731 genes were differentially expressed comparing individuals fed with the artificial diet and with their natural food, among which most (77.1%) were down regulated. No significant induced expression of xenobiotic transporters and detoxification enzymes were observed when T. urticae were fed with the artificial diet. In contrast, differentially expressed genes were mainly enriched in digestive related terms, especially in lipid metabolism related pathways, with most genes down regulated. Our results indicated the significance in further investigating lipid demand and metabolism of T. urticae to improve its mass rearing techniques.

AbstractComponents of male seminal fluids are known to stimulate fecundity and fertility in females of numerous insect species and paternal effects on offspring phenotype are also known, but no studies have yet demonstrated links between male effects on female reproduction and those on progeny phenotype. In separate laboratory experiments employing 10-day-old virgin females ofCheilomenes sexmaculata(F.), we varied male age and mating history to manipulate levels of male allomones and found that the magnitude of paternal effects on progeny phenotype was correlated with stimulation of female reproduction. Older virgin males remained in copula longer than younger ones, induced higher levels of female fecundity, and sired progeny that developed faster to yield heavier adults. When male age was held constant (13 days), egg fertility declined as a function of previous male copulations, progeny developmental times increased, and the adult weight of daughters declined. These results suggest that male epigenetic effects on progeny phenotype act in concert with female reproductive stimulation; both categories of effects increased as a consequence of male celibacy (factor accumulation), and diminished as a function of previous matings (factor depletion). Male factors that influence female reproduction are implicated in sexual conflict and parental effects may extend this conflict to offspring phenotype. Whereas mothers control the timing of oviposition events and can use maternal effects to tailor progeny phenotypes to prevailing or anticipated conditions, fathers cannot. Since females remate and dilute paternity in polyandrous systems, paternal fitness will be increased by linking paternal effects to female fecundity stimulation, so that more benefits accrue to the male's own progeny.
