Abstract

Surveys from May 2003 to January 2004 in South Sumatera were conducted to determine parasitoid attacking Plutella xylostella (L.) and to estimate P. xylostella parasitization by the parasitoids. The eggs and the larvae of P. xylostella were collected from brassicaceous crops, i.e. mustard, Indian mustard, and cabbage. Six parasitoids found were Trichogrammatoidea cojuangcoi Nagaraja (Hymenoptera: Trichogrammatidae), Cotesia plutellae (Kurdj.) (Hymenoptera: Braconidae), Diadegma semiclausum Hellen (Hymenoptera: Ichneumonidae), Oomyzus sokolowskii (Kurdj.) (Hymenoptera: Eulophidae), Tetrastichus (Hymenoptera: Eulophidae), and a ceraphronid wasp (unidentified species). Trichogrammatoidea cojuangcoi parasitized P. xylostella eggs, however, the others parasitized the larvae except the ceraphronid wasp. In South Sumatera, the ceraphronid wasp was reported for the first time parasitizing D. semiclausum pupae, and its parasitization reached 6.2%. Oomyzus sokolowskii and Tetrastichus were found in this area for the first time, as well. In the highland, D. semiclausum was the most abundant compared to the others where its parasitization reached 79.2%. In the lowland P. xylostella larvae was mainly attacked by C. plutellae with the parasitization reaching 64.9%. In the dry and rainy seasons, the parasitization was mainly exerted by T. cojuangcoi (77.0%) and D. semiclausum (79.2%).

Abstract

Liriomyza sativae is a polyphagous agromyzid leafminer and it has invaded large part of world, i.e Hemiptarsenus varicornis, Gronotoma micromorpha, and Opius dissitus. This research were conducted to investigate progeny, immature development period, longevity of female parasitoids of L. sativae, and to study female parasitoid behaviour in host finding. Host finding behaviour was observed by examining their visit frequency to the leaves that mined by leafminer larvae and healthy leaves. Results showed that H. varicornis produced more progenies (10.70 + 2.58 progenies/female), but not significantly different (P < 0.05) from progenies produced by G. micromorpha (9.90 + 3.81 progenies/female) and O. dissitus (9.60 + 3.31 progenies/female). The immature development period of G. micromorpha (25.65 + 0.38 days) was found to be longer than H. varicornis (16.14 ± 1.20 days) and O. dissitus (14.03 + 0.22 days). Significant different (P = 0.1014) of adult longevity was not found among H. varicornis (9.22 + 2.48 days), G. micromorpha (7.25 + 1.34 days), and O. dissitus (8.74 + 2.18 days). Our analyses also indicated that G. micromorpha and O. dissitus found their hosts based on the larvae mining, however, H. varicornis performed it randomly. Based on the number of progeny and longevity of adult female, all parasitoids tested may have a potential as biological control agents of leafminer, L. sativae. Key words: fecundity, longevity, behavior, Hemiptarsenus, Gronotoma, Opius, Liriomyza sativae

Abstract

Species Diversity and Abundance Comparison of the Soil-dwelling predatory-arthropods Inhabiting Fields Applied by Insecticide and without Insecticide Application. Studies on soil-dwelling predatory arthropods were carried out in lowland areas of South Sumatra, with objectives to analyze the species diversity and abundance of the predatoryarthropods inhabiting fields applied by synthetic insecticide, bioinsecticide, and without insecticide application. The predatory arthropods were sampled using pitfall traps. Indices of diversity and community similarities were applied to analyze the data. Results indicated that the arthropods inhabiting field without insecticide application had the highest diversity and abundance compared to other treatments. Predatory community similarities between those on the field without insecticide application and applied by bioinsecticide were higher compared to the fields applied by synthetic insecticide. KEY WORDS: diversity, abundance, predatory arthropod.

Abstract

The study was conducted to find out: suitability of eggs of Corcyra cephlalonica Stainton as a factitious host of S. incertulas egg parasitoids and techniques of parasitoid stock provision, serially conducted from February 2011 to December 2011. The researches were carried out in four laboratory experiments, consisting of the study of ultraviolet (UV) irradiation on C. cephalonica eggs; suitability of C. cephlalonica eggs as a factitious host of Telenomus rowani Gahan, Trichogramma japonicum Ashmead and Tetrastichus schoenobii Ferriere; storage method of C. cephalonica eggs; and storage method of parasitoids. The research design was suited to the research needs. The results showed that; The C. cephalonica eggs irradiated by the minimum of 28.48 minute 15 watt ultraviolet (UV) at a distance +15 cm between the lamp and the eggs could suppress the hatching eggs to zero (no emerged larvae). Among the three species of egg parasitoids of S. incertulas found in Jambi Province, only T. japonicum could be rearing on C. cephalonica eggs. The relationship between storage duration of C. cephalonica eggs irradiated by the 30 minutes 15 watts UV at 5oC and the emerged T. japonicum wasps was expressed by the equation of y = 31.04-1.151x, R²=0.865, P=0.000. The storage of T. japonicum pupae for six weeks at 5°C did not reduce the number of emerged T. japonicum wasps. The emerged wasps reduced significantly if the storage duration of T. japonicum pupae was increased to seven weeks or more.

Abstract

In fresh swamp areas of South Sumatra, papaya mealybug, Paracoccus marginatus (Hemiptera: Pseudococcidae) could cause severe damage to young papaya trees and decreased the fruit quality. The objective of this research was to bioassay test of the bioinsecticide Beauveria bassiana againts nymphs of P. marginatus. B. bassiana was conducted on rice medium. The bioinsecticide was formulated using dried compost, compost gram,  paddy ash,  paddy bran, woody powder, paddy bran mixed with woody powder,  compost enriched with  Trichoderma virens. Controls used were sterile water (control 1) and isolate of B. bassiana (control 2). Results showed that conidial viability of B. bassiana on control 2 was the highest (46.33%). The viability of control 2 was not significantly different from the formulations with carrier of the paddy bran, the paddy bran mixed with woody powder, and the compost enriched with T. virens. The highest nymph mortality (82.86%) was found on formulation of  compost enriched with T. virens and was significantly different from other treatments. The lowest  visibly (73.48%) occured on formulation of paddy ash, and was significantly different from other treatments. Mortality on control 1 on average was 29.52%, whereas control 2 averaged of 75.71%. The shortest median lethal time (LT50) (3.55 days) was found on formulation of compost enriched with T.  virens but the longest one (3.73 days) occured on the formulation of paddy ash. Overall, the most effective bioinsecticide was the formulation of compost enriched with T. virens.Key words: bioinsecticide, Beauveria bassiana, Paracoccus marginatus

Abstract

There are approximately 1.4 million hectares of swampy area in South Sumatera, but only 12% of those are being used as farm and plantation. The purpose of this research was to investigate the similarity of arthropod community inhabiting swampy rice field and its surrounding area. This research was conducted in South Sumatera Province covering regency of Musi Banyuasin and Palembang. Four types of swampy area were selected from each location, i.e. rice field, thicket, bush, and swampy land inhabited by broad-leaf weeds. Pitfall trap used to collect arthropod and it installed at five different times. i.e. 15 days before rice planting, one month, two months, and three months after planting, and 15 days after harvest time. The result showed that relative abundance of predatory arthropod dwelling soil in rice field was 95.03%, and habitat surrounding rice field was 95.12–97.21%. The level of similarity of arthropod species between rice field ecosystem and its surrounding area ranged from 0.73 to 0.84. Thus, the surrounding area of rice field probably can be used as catchment area of predatory arthropod and other pests during planting season.Key words: rice, rice field, biological control
