Abstract

Pests of star fruit in Blitar District, East Java. Pest attack causes the production of star fruit decreases. This study aim was to identify the pests of star fruit in Blitar District which could provide an information about pest species, damage symptoms and damage intensity. The research was conducted during August – September 2014 in Gogodeso, Karangsono and Pojok Villages at Blitar District, East Java. Observations of the pests ware done by determining the four locations of plantation on each villages randomly. Three plants sample were choosen in each plantation location diagonally. Each plant was divided into four quadrant according to wind directions. One branch in the bottom was choosen in each quadrant. Nine species were recorded as pests of starfruit in Blitar district. Pest was identified on the leaf was Pteroma plagiophleps, on the branch was Zeuzera coffeae, on the flower were Toxoptera aurantii and Maconellicoccus hirsutus, whereas those on the fruit were Toxoptera aurantii, Maconellicoccus hirsutus, Thrips javanicus, Helopeltis bradyi, Cryptophlebia leucotreta, Bactrocera dorsalis, and Bactrocera carambolae. The population density of M. hirsutus was higher in Karangsono than in other villages. The highest damage intensity was caused by Bactrocera spp., C. leucotreta and H. bradyi (occured in Gogodeso), whereas the highest damage intensity of T. javanicus occurred in Pojok.

Abstract

Cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae): Geographic distribution in Java and initiation of biological control. Cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Psedococcidae), is a recently introduced pest in Indonesia. Parasitoid Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) was imported to control the pest. Studies were conducted to determine geographic distribution of P. manihoti throughout Java, and to evaluate the potential of the parasitoid as a biological control agent. Geographic distribution of the pest was determined through field survey, whereas evaluation of the parasitoid was studied through cage experiment and field release. Our survey revealed that the cassava mealybug has spread throughout Java. Heavy infestations caused shortened and distorted stems, complete defoliation, and stunted growth. In cages containing only mealybugs, all cassava plants (100%) died after two months. Whereas in cages containing both mealybugs and three pairs of parasitoid, rate of parasitization was 25% and plant mortality 20%. Parasitoids released in the field were able to survive, reproduce, and establish under Bogor climatic condition. These might indicate that parasitoid A. lopezi is a potential natural enemy to be used in biological control program of the cassava mealybug.

Abstract

Diversity of parasitic Hymenoptera in different ecosystem types in Central Bangka, Bangka-Belitung Islands.Hymenoptera richness is dominated by parasitic species. More than 80% of Hymenoptera play a role as parasitoid on arthropods that are mostly insects. Diversity of parasitic Hymenoptera is widely studied in various types of terrestrial ecosystems including agro-ecosystem and non-agro-ecosystem. This study aimed to invent and compare the diversity of parasitic Hymenoptera in three different ecosystems, i.e., forest, oil palm plantation, and ex-tin mining. The location was located in Central Bangka Regency, Bangka Island. The study was conducted in Juli 2014 until October 2015. Parasitic Hymenoptera was collected with insect sweep net and yellow pan trap on one transect line with 1000 m length. Parasitic Hymenoptera were found on forest as much as 732 morphospecies, 326 morphospecies on oil palm plantations, and 293 morphospecies on ex-tin mining. Diversity and abundance of parasitic Hymenoptera on forest was higher than oil palm plantation and ex-tin mining area. Braconidae family was found dominant on forest, however on oil palm plantation and extin mining area the dominant family was Scelionidae.

Abstract

Effect of pest management systems to the insect pests population on Anjasmoro and Wilis soybean varieties. The integrated pest management (IPM) is a pest control approach which is based on ecological and economic considerations. The objective of this research was to study the effect of different pest management systems on the insect pest population using two soybean varieties, Anjasmoro and Wilis.The experiments were done in a randomized complete block design, repeated twice. The pest management systems under the different plots were integrated pest management, non-chemical control, chemical control, and the control (which received neither chemicals nor IPM). Observations were made on the pest population and the intensity of the damage caused by primary soybean pests. The primary pests observed were Ophiomya phaseoli, Aphis gossypii, Lamprosema indicata, Spodoptera litura, Bemisia tabaci, Riptortus linearis and Etiella zinckenella. Integrated pest management significantly affect the population of whitefly on Anjasmoro variety but not on Wilis variety. The populations of bean fly, aphid, leaf roller, armyworm, stink bug and pod borer were not affected by pest management system. The lower yield of Anjasmoro variety was attributed to the attack by a viral infection whose disease incidence reached 80% on the plots without a pest management system. IPM management system was more efficient than chemical management system.

Abstract

Lepidopteran community and its parasitoid on cucumber field in Bogor, Sukabumi and Cianjur District, West Java. Cucumber is one of horticultural commodities that are widely cultivated in Indonesia, but information related to Lepidoptera pests and their parasitoids are limited. The aim of this study was to obtain information about Lepidopteran community on cucumber and their parasitoid diversity. Lepidopteran larvae were collected from 16 cucumber sites in the District of Bogor, Sukabumi and Cianjur in November 2014 until May 2015. Larvae were collected from each cucumber plant follow along 60 m transects. Larvae were collected from the field then brought to the laboratory. All larvae were then reared on cucumber leaves until pupation and parasitoids emerged. The data obtained were tested by analysis of the mean and analysis of variance (One way ANOVA) using the program R Stat. The results showed that cucumber plants were attacked by six species (morphospecies) belonging to four families of Lepidoptera. Diaphania indica (Saunders) (Lepidoptera: Crambidae) is the most abundant species found. All species (morphospecies) of Lepidoptera are more common when the cucumber plants are in the generative growth stage. Our result further showed that D. indica was attacked by 9 parasitoid larvae and 3 parasitoid pupae, C. chalcites (Lepidoptera: Noctuidae) by 5 parasitoids dan S. litura (Lepidoptera: Noctuidae) by 2 parasitoids. A braconid, Apanteles taragamae, is the most common parasitoid of D. indica found in the field. Its parasitism rate can reach 27% in the field. Overall, this research revealed that a number of parasitoids, that were found attacking Lepidopteran on cucumber indicates their potential use as biological control agents in this agroecosystems.

Abstract

Sago (Metroxylon sagu Rottb) in Maluku grow naturally to form sago forest ecosystem. Hymenoptera in the sago forest ecosystem has not been studied. This study aims to examine the diversity of Hymenopterous parasitoids in sago forests in Maluku. The research was conducted in Ariate, Eti, Waisamu, Rutong, Tawiri, and Tulehu in September 2015 - October 2016. Hymenopterous parasitoids were collected through swing nets, light traps, yellow pan traps, and pitfall traps. Results the abundance of hymenopterous parasitoids in six sago areas in Maluku was found to be 14 families and 32 species. The morphoses of morphospecies are 68 morphospecies of Sago Ariate forest 32 morphospecies, Eti 37 morphospecies, Waisamu 9 morphospecies, Rutong 11 morphospecies, Tawiri 19 morphospecies, and Tulehu 37 morphospecies. The high diversity index (2.18 - 3.55) per location, Morphospesies wealth of Tulehu is  higher than other location, while the individual abundance of Ariate is higher than other villages. The average relative abundance of Scelionidae, Scoliidae and Ichneumonidae families was higher by 26.46%, 15.95%, and 10.89%, respectively. There are three families with high morphospecies and individual abundance in each sago area ie Scoliidae in sago forest area of Ariate and Waesamu, Scelionidae on Rutang, Eti, and Tawiri sago wood area, while Eulophidae on sago Tulehu area. There are 12 unique species or species with only certain locations and none in other locations, each Ariate (2 species), Eti (2 species), and Tulehu (8 species).ABSTRAKSagu (Metroxylon spp.) merupakan tanaman sosial, budaya dan ekonomi di Maluku dengan potensi hutan sagu cukup tersedia.

Abstract

Aspects of biology of Acerophagus papayae Noyes & Schauff (Hymenoptera: Encyrtidae), parasitoid of papaya mealybug. Acerophagus papayae Noyes & Schauff (Hymenoptera: Encyrtidae) is an important parasitoid of the papaya mealybug, Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae). The study was conducted with the objective to determine various aspects of the biology of A. papayae which include the effect of diet on adult longevity, fecundity and progeny, host stage susceptibility and preference, the effect of host stages on immature development, body size, and sex ratio of progenies.  Effects of diet on adult longevity was done in the absence of hosts. Fecundity was measured by the number of mealybugs parasitized. Host stage susceptibility and preference were carried out by exposing 2nd  and 3rd  nymphal instars and pre-reproductive adults of mealybugs to parasitoids. Results showed adult parasitoids fed with 10% honey solution lived almost fourfold longer than those provided only water. A. papayae parasitized 30.1±4.92 mealybugs, with a range of 13-60 mealybugs, during 5.8 days of adult life.  In no-choice (susceptibility) and paired-choice (preference) tests, the percentage of parasitized hosts were significantly greater in 2nd and 3rd instar nymphs than in adults. The mean immature developmental time of A. papayae was longer when the parasitoids develop in large host. Developmental time of male parasitoids was shorter than the females. Female wasps which emerged from hosts parasitized at the 3rd instar nymphs and adults were significantly larger than those from the 2nd instar nymphs.  Sex ratios of the offspring emerged from hosts that were parasitized as 2nd instars were strongly male-biased, while the later stages yielded more females than males.
