Abstract

Demographic parameter Parasitoid Hemiptarsenus varicornis Girault (Hymenoptera: Eulophidae) on Leafminer Liriomyza huidobrensis. Hemiptarsenus varicornis Girault (Hymenoptera: Eulophidae) is the most common parasitoid associated with larvae of potato leafminer Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae) in Indonesia. The leaf miner was reared on redbean. Demographic parameters was determined by observation of 50 larvae. Daily mortality and fertility were calculated using a life table analysis. Life table analysis showed that the net reproductive rate (Ro) was 18.021 females per generation, instrinsic growth rate ( r ) was 0.208 female offspring per female per day, limited increased rate ( ë ) was 1.231 individuals per day, generation time ( T ) was 13.9 days, and total reproduction value (RVx) was 80.847 and its peak was reached when adults were three days old. Leslie matrix simulation showed proportions of parasitoid’s egg, larva, pupa, and adult. Which are 35%, 30,6%, and 18%, respectively were stabilized since 40 days after release.

Abstract

Araecerus fasciculatus (Coleoptera: Anthribidae) is a primary pest mostly found in cocoa bean storage. Controlling A. fascuculatus is highly necessary, as this action would also reduce infestation of secondary pests. Utilization of natural materials as bait or trap is one applicable method to lessen damage and loss during storage. Vitex trifolia L., Acorus colomus L., and Andropogon nardus L are plant species that posess insecticidal properties that can be used to control post harvest pests. Materials used in this experiment are leaves of V. trifolia, rhizome of A. colomus and leaves of A. nardus. The three types of materials are blended and sieved with 300 mesh until finely broken up for make powder formulation. As much as 1 g of powder extract was taken then mixed with additional substract (water + CMC + saw dusts). The mixtures were then shaped in the form of ellipse resembling cocoa beans with approximately similar weight of 0.6 g (± 20 beans). Results show that V. trifolia and A. nardus are highly repellent (90.5 % and 94.5%) to A. fasciculatus, and crhizome of A. colomus is attractant to A. fasciculatus.

Abstract

Spodoptera frugiperda is a novel invasive pest of maize crops. Therefore, studies on this pest are limited. Research on the use of artificial diets in S. frugiperda larvae rearing is essential to facilitate the provision of test larva stocks for lab-scale study purposes. The aim of this research was to figure out the effect of an artificial diet from soybeans as a protein source on S. frugiperda rearing. The parameters observed in this research were larval-stage longevity, larval survival rate, pupa size, sex ratio, pupal-stage longevity, pupal survival rate, fecundity, and nutritional index. The results showed that an artificial diet with soybeans had a significant effect on sex ratio, pupal survival rate, relative consumption rate (RCR) 4.89 g/g/day (4th instar); 1.99 g/g/day (5th instar), approximate digestibility (AD) 98.39% (4th instar); 95.45% (5th instar), and fecundity, but it did not have any significant effect on larval-stage longevity, larval survival rate, pupa size, pupal-stage longevity, the efficiency of conversion of ingested food (ECI) 3.68% (4th instar); 7.84% (5th instar), and efficiency of conversion of digested food (ECD) 3.76% (4th instar); 8.27% (5th instar). Artificial diet-based soybean was highly potential to be used in S. frugiperda rearing.
