Abstract

The structure of agricultural landscape, both of its composition and configuration can affect the presence of predators and parasitoids, and influence the effectiveness of biological control. This study was aimed to examine the relationship between landscape structure and the diversity of Hymenoptera parasitoids in long bean fields in Bogor, West Java. In total, six long bean fields were selected and quantified within a radius 500 m from long bean field. In each long bean field, Hymenoptera parasitoids were sampled in a 50 m x 25 m plot using direct observation. The research result found 283 individuals of Hymenoptera parasitoids belong to 9 families and 31 species. Based on the Mantel test, the landscape structure did not affect the species composition of parasitoids in long bean. However, at class scale, landscape composition especially crop field and semi-natural habitat have an effect on parasitoid abundance. Agricultural landscape with higher patch number of crop fields tends to have higher parasitoid abundance. It indicates that landscape composition at class scale is more affected to Hymenoptera parasitoids than at landscape scale.

Abstract

Sycanus aurantiacus Ishikawa & Okajima, found in Bali, was first described in 2007 as a new harpactorine species based on morphological and biological characteristics; however, its genome has not yet been sequenced. In this study, we examine the mitochondrial cytochrome oxidase subunit I (MtCOI) nucleotide sequence of S. aurantiacus in order to determine whether it represents a new harpactorine species. A sample from Pancasari, Bali, Indonesia was collected at the same location S. aurantiacus was first discovered in 2007. The selected mtCOI gene (650 bp) was successfully amplified using mtCOI primer pairs LCO1490 and HCO2198, and the resulting MtCOI sequence of the S. aurantiacus sample was compared with those from other hapactorine species recorded in GenBank. This comparison revealed low genetic similarity between S. aurantiacus and most other harpactorine species worldwide, except for the Genus Sycanus (JQ888697) from USA whose mtCOI shares approximately 91% similarity with the Pancasari sample. Phylogenetic analysis indicated a close genetic relationship between Sycanus from Bali and the Genus Sycanus (JQ888697) from the USA. The mtCOI sequence of S. aurantiacus had not been recorded previously, and our comparison with existing Sycanus sequences provides support to the understanding that S. aurantiacus is indeed its own species.

Abstract

Tetranychus kanzawai is a species of mite that can cause agricultural crop losses of about 60–90%. One way to control pests that are environmental friendly is to use the predatory beetle Stethorus punctillum. This study aims to determine the demographic statistics, preferences, and functional response of S. punctillum on T. kanzawai. Observation of the S. punctillum biological using 100 eggs, observations were made of the number of individuals living until adult females produce offspring. Preferences of S. punctillum using 50 eggs and 50 nymphs and T. kanzawai adults, observations were made on the number of  T. kanzawai preyed by instar larvae I, II, III, IV, and S. punctillum adults. Functional response is done by giving S. punctillum prey as many as 30, 40, 50, 60, 70, 80 eggs T. kanzawai, observations made on the remaining number of eggs. S. punctillum eggs last for 7.01 ± 0.72 days. First instar larvae lasted for 4.84 ± 0.51 days, second instar 3.16 ± 0.52 days, third instar 3.00 ± 0.27 days, and IV instar 2.48 ± 0.50 days. Females lay eggs 64.47 ± 2.37 eggs. Gross reproduction rate (GRR) of S. punctillum 64.29 individuals/generation, net reproduction rate (Ro) of 17.18 individuals/female/generation, intrinsic accretion rate (r) of  0.27 individuals/female/day, average the generation period (T) is 62.41 days, and the double time (DT) is 2.51 days. The data shows that S. punctillum has a preference for T. kanzawai egg stages and type III functional response curves with Th 7.68 minutes and a 0.22 eggs/minute.

Abstract

The adult female mosquito identification is an important aspect in vector-borne disease surveillances and vector control strategies. Indonesia with high mosquito species diversity faces the problem related to the presence of several important vector-borne diseases, including malaria, chikungunya, dengue fever, filariasis, and Japanese encephalitis. Updated key to the mosquitoes is needed to provide up to date information of the appropriate disease vectors in Indonesia. Currently, before the publication of the checklist of Indonesian mosquitoes by O’Connor & Sopa (1981), there has been no recent information on the number of mosquito genera and subgenera in Indonesia. This article aims to deliver updates on mosquito taxonomic information and provide the identification key of the mosquito genera in Indonesia. So far, a total of 21 genera and 63 mosquito subgenera has been reported in this country. Overall there are three genera and 15 subgenera added from the 1981’s mosquito checklist, Verrallina, Lutzia, and Kimia are added in the list of new mosquito genera.

Abstract

Stingless bees are widely distributed in tropical regions including Indonesia, and currently three species of stingless bee have been recorded in the Moluccas. The aims of this study were to explore the species and distribution of stingless bees in the five islands in the Moluccas (Seram, Ambon, Haruku, Saparua, and Nusalaut island) and compare the morphometric variations of stingless bees within and among islands. The samples of stingless bees were identified based on twelve morphological characters, resulting in two species of Tetragonula fuscobalteata (Cameron) and T. sapiens. (Cockerell). T. fuscobalteata found to be a new record in the Moluccas, and showed significantly lower morphometric parameters compared to those of T. sapiens (P < 0.001). Based on non-metric multidimensional scaling (NMDS) analysis, the combination of twelve morphometric parameters between T. fuscobalteata and T. sapiens were significantly different. Almost all morphometric parameters of T. fuscobalteata showed highly varied among islands, except the width of gena of this stingless bees. T. fuscobalteata from Ambon, Haruku, Saparua, and Nusalaut were mostly clustered based on NMDS analysis, while those from Seram show high variations. This study found T. sapiens in three different islands, Seram, Ambon, and Haruku. Width of thorax, mesonotum, and propodeum length of T. sapiens were significantly different among these three islands (P < 0.001). This study has contributed to the new distribution data of T. fuscobalteata and T. sapiens in the Moluccas and showed variation of morphometric parameters of the two stingless bee species among islands in the Moluccas.

Abstract

The community structure of cerambycid beetles in an area is closely related to the heterogeneity of woody plants. Pangandaran Nature Reserve is forest located in the peninsula and has unique fauna and flora communities. The study aims to analyze the diversity and abundance of cerambycid beetles in the Pangandaran Nature Reserve. To attract the cerambycid beetles, we used branches of jackfruit (Artocarpus heterophyllus) and fig (Ficus septica) as traps. Traps were tied in a tree or log about 1.5 m from the ground in the Nature Recreation Park and the Nature Reserve, each area with 2 locations. Collection of beetles were carried out by beating method. A total of 574 individuals cerambycid beetles were found, belonging to 1 subfamily, 8 tribes, 12 genera, and 20 species. The highest species diversity of beetles was found in Nature Recreation Park-1 (H’ = 2.09, E = 0.74), followed by Nature Reserve-2 (H’ = 1.75, E = 0.68), Nature Recreation Park-2 (H’ = 1.70, E = 0.71), and Nature Reserve-1 (H’ = 1.52, E = 0.69). Four species of beetles found in high abundance were Sybra binotata Gahan (229 individuals), Nyctimenius javanus (74 individuals), Atimura bacillina Pascoe (67 individuals), and Acalolepta rusticatrix (Fabricius) (45 individuals). The number of individual beetles collected in Artocarpus (342 individuals) was higher than Ficus traps (232 individuals). This study identified seven endemic beetles of Java, i.e., Myagrus javanicus Breuning, Cacia curta Breuning, Sybra obliquefasciata Breuning, Sybra fuscotriangularis Breuning, Pterolophia triangularis Breuning, N. javanus, and Exocentrus artocarpi Fisher.

Abstract

Habitat conditions around cocoa plantations which include canopy cover and lower vegetation (weeds) as well as the presence of mealybugs trophobiont (Planococcus sp.) can affect the diversity and abundance of ants. The objective of this research was to study the diversity and abundance of ants in cocoa plantations and to study the effect of habitat conditions and the presence of trophobiont (Planococcus sp.) on species richness and ant abundance. The research was carried out in 12 locations spread across five districts in East Java. Ant samples were collected by tuna bait and direct collection. The results obtained 5,475 individuals and 8 species of ants. The most dominant ants and found in all areas were Dolichoderus thoracicus (Smith) and Technomyrmex albipes (Smith). Based on the regression analysis, there is a relationship between canopy cover and vegetation diversity with ant species, but not with abundance, meanwhile the presence of trophobiont shows a positive correlation with ant abundance. The habitat conditions for cocoa cultivation and the presence of trophobiont affect the diversity and abundance of ants in cocoa plantations.
