Abstract

Spodoptera frugiperda damage in South Sumatra reached 100%. Biological control of S. frugiperda using entomopathogenic fungi has been widely practiced. This study aimed to determine S. frugiperda larval abundance and infestation in maize inoculated with endophytic entomopathogenic fungi. The three fungal isolates used in the current study consisted of one species of Beauveria bassiana (isolate code: JgSPK), one species of Penicillium citrinum (isolate code: JaTpOi (2)) and one species of Metarhizium anisopliae (isolate code: CaTpPga). Egg and larval, incidence and severity of S. frugiferda infestation were observed. All endophytic entomopathogenic fungal isolates could siginifcantly decrease the incidence and severity caused by S. frugiperda larvae. Corn seeds treated with endophytic entomopathogenic fungi did not affect the population of eggs and larvae. Fluctuations of the egg and larval population tended to be influenced by corn age.

Abstract

Yudianti, Y., Herlinda, S., Millinia, J., Rindiani, D. E., Marlina, D., & Netaria, N. (2023). Meliponiculture of Stingless bee (Hymenoptera: Apidae) in Muara Enim Regency, South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 333-344). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The survival of stingless bee populations is threatened, partly due to loss of natural habitat due to land use change and deforestation. This study aimed to determine how to cultivate stingless bees in Muara Enim Regency, South Sumatra. The method used is survey or direct observation in the field to observe tools and materials for making nest boxes, multiplying colonies, harvesting honey, packaging honey, marketing and conducting interviews with stingless bee farmers. This study interviewed one stingless bee farmer. Tools and materials used in making nests include trees, boards, nails, hammers, zinc, plastic, bricks, saws. The development and number of colonies depends on the forage plants around the hive. Honey harvesting tools and materials include a honey suction machine, sticks/toothpicks and honey storage. Honey packaging uses labeled syrup bottles. The resulting stingless bee honey products are sold in the Prabumulih traditional market, Palembang, social media and come directly to the stingless bee cultivation garden. The results showed that stingless bee cultivation is carried out by starting with land preparation, then finding colonies, moving colonies, maintaining colonies and harvesting honey. Stingless bee cultivation methods should be socialized to the community so that they can practice stingless bee cultivation which is beneficial for agricultural ecosystems, human health and also as a source of livelihood.

Abstract

The quality of artificial diets is important to produce high quality cultures of S. frugiperda. The research aimed to determine the effect of artificial diets based on wild plants on the growth and development of Spodoptera frugiperda. The plants used for enriching artificial diets were Zea mays (control), Ipomoea aquatic, Ipomoea reptans, Amaranthus hybridus, Morus rubra, Brachiaria mutica, and Setaria sphacelata. The results showed that S. frugiperda larvae consuming artificial diets enriched with A. hybridus, Z. mays, I. reptans, and I. aquatic leaves had higher body weight, lower larval mortality and abnormal pupae compared to those of B. mutica, S. sphacelata and M. rubra leaves. The adult females from larvae-consuming diets enriched with A. hybridus, Z. mays, I. reptans, I. aquatica, and S. sphacelata leaves had higher fecundity compared to those of other diets. However, diet enriched with S. sphacelata leaves caused higher larval mortality. Thus, the more suitable diets to increase the larval growth and survival, and adult emergence and fecundity were the diets enriched with wild host plants (A. hybridus, I. reptans, and I. aquatic leaves). Using weed or wild host plant leaves to produce artificial diets is feasible for mass-rearing S. frugiperda.
