Abstract

Spodoptera pectinicornis is a biological control agent that has a great potential to control water lettuce weeds. Its existence in nature however is still limited, so a mass propagation is needed by rearing S. pectinicornis imagoes to produce eggs and to hatch them into larvae of 4 days old. The 4-year larvae were then released by putting water lettuces that contained active larvae into the target area. Observation results on the percentage of damage in the watershed location for 5 times of observation consecutively was 25%, 50%, 50%, 75% and 90%. The magnitude of damage showed that S. pectinicornis was able to adapt well, so it could perform eating activities and cause damage to the water lettuces. Meanwhile, at the release site of rice field, the percentage of damage was 0%, 25%, 35%, 25% and 10%. The downward trend in the level of S. pectinicornis attacks was due to its inability to keep pace with the growth and development of water lettuces. High level of rainfall caused the water lettuces to increase its size and the number of its tillers so that they could colonize these waters. The fact that S. pectinicornis still has the ability to destroy the water lettuces gives great hope to the control efforts. However, thorough evaluation and assessment are required on all aspects, such as the biological control agents, weed targets, organisms associated with them, and the state of the environment so as to minimize the possibility of failure in the field. Keywords: augmentation, biological agents, Pistia stratiotes, Spodoptera pectinicornis

Abstract

Among other provinces in Indonesia, South Kalimantan used to be known as one of the most famous local suppliers of bananas, especially for Java and Bali. However, since 2006 the productivity has declined dramatically due to the disruption of plant diseases. The early, fast, accurate and precise detection of the disease is needed in order to control the disease appropriately. One of the most useful, fast and accurate diagnostics that was carried out in this research was Polymerase Chain Reaction (PCR). This molecular technique has never been carried out before to detect banana diseases in South Kalimantan. This research aimed to identify the sick banana plants taken from 13 locations in 6 (six) regencies in South Kalimantan Indonesia, representing banana planting areas: Banjarbaru City, Batola, Tanah Laut, Tapin, Hulu Sungai Selatan and Hulu Sungai Tengah regencies. The results showed that the disease of all banana plant samples was positively identified as Blood Diseased Bacteria (BDB). It was established by the electroforesis result after being viewed under UV illumination that the band was at the same position as the positive control (BDB), 317 bp.7 bp.

Abstract

The table of life can provide information on birth (natality), death (mortality) and the opportunity to breed, so it can be used as a parameter of the behavior of population development.The purpose of this study was to determine the calculation of life table of S. pectinicornis Hampson as biological control agent of water lettuce (P. stratiotes) weed.The table of life is done by observing survival ability, mortality and fecundity of S. pectinicornis of a cohort of 300 eggs by looking at all the stages from egg, larva, pupa, and imago, and fecundity of female imago per day. The research was conducted in a condition of unlimited food resources and environment free of natural enemies. Parameters observed were gross reproductive rate (GRR), net reproductive rate (Ro), average of generation time (T), intrinsic rate of growth (r), and limited rate of growth (λ). The research result of the life table calculation showed that GRR value was 350.29, the value of net reproductive rate (Ro) was 19.59 descendants, the average of generation time (T) was 29.47 days, the value of intrinsic rate of accretion (r) was 0.10 and the value of limited rate of accretion (λ) was 1.11.

Abstract

This study aims to identify and determine the parasitic level of Bactrocera mcgregori parasitoid from melinjo fruit (Gnetum gnemon) from Tanah Laut district and Banjarbaru Kalimatan Selatan City. The identification results of the three parasitoids showed the characteristics of the Hymenoptera order, the family Braconidae. The three parasitoids are Psytallia flecheri habitus (Silvestri) parasitoid, Psytallia lounsburyi (Silvestri) and Diachasmimorpha longicaudata (Cameron).
