Abstract

Pest attack in nutmeg is a cause of major damage both in the field and in storage. Information on the diversity of pest insects in storage, harvesting methods, and good drying needs to be known to reduce the level of damage to nutmeg. This study aims to determine the diversity of insect pests and the percentage of nutmeg damage due to various postharvest treatments. Nutmeg was packed in jute bag and stored for four months under warehouse conditions. Each jute bag containing nutmeg is treated based on the origin of nutmeg (picked from a tree or picked up on the ground), drying method (sunshine or fogging), and shell or without shells with each treatment replicated three times. Sampling of numtag was conducted after four month to calculate the number of each insect species found, determine the insect population, and determine the percentage of damaged seeds. Four insect species were found in nutmeg kernels in almost various treatments. They were Araecerus fasciculatus ((Degeer) (Coleoptera: Anthribidae), Carpophilus dimidiatus (Fabricius) (Coleoptera: Nitidulidae), Oryzaephilus surinamensis (Linnaeus) (Coleoptera: Silvanidae), and Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The dominant species was A. fasciculatus. The percentage of damaged kernels derived from nutmeg kernels fallen on the ground, dried either using sun-drying or smoke-drying, either in-shell or without shell, were higher than the kernels derived from ripe fruitswith various treatments. The recommendation of this research result is good postharvest handling of  nutmeg to prevent insect infestation should be conducted by collecting nutmeg derived from ripe fruits picked from the trees, nutmeg in-shell either sun-dried or smoke-dried, and storing nutmeg in-shell.

Abstract

Datura metel L. is a type of shrub that has a wooden stem, hard, and thick. Datura leaves contain chemical compounds alkaloids, saponins, flavonoids, and phenols. Based on the chemical content, datura leaves potentially as an alternative insecticide that can replace the use of synthetic insecticides. The use of synthetic insecticides in controlling the Aedes aegypti L. population has had a negative impact, such as environmental pollution, public health problems, and vector resistance. The purpose of this study was to study the effect datura leaf extract as a biochemical insecticide on inhibiting egg hatching and life cycles of Ae. aegypti. The research was conducted at Entomology Laboratory, Public Health Faculty, Universitas Diponegoro. This type of research was a true experiment with four replications and with concentration treatment i.e. 125, 250, 500, 750, 1000, and 1250 ppm. The subjects of this study were egg fertile of Ae. aegypti which were 25 eggs in each container and the total number of samples was 800 eggs. The used method for extraction was maceration. The result of probit analysis showed the activity of amethyst extract insecticide with LC50 = 199.34 ppm and LC90 = 749.08 ppm. The result of ANOVA showed a difference in the average number of non-hatching eggs due to exposure of datura leaf extract (P = 0,001). The percentage of Ae. aegypti egg hatching failure was lowest at concentration 125 ppm (41%) and the highest was at concentration 1250 ppm (98%). The survival of larvae, pupa, and mosquitoes was highest at concentration 125 ppm (49.18%, 55.17%, and 43.75% respectively). In conclusion, the datura leaf extracts potentially as a biochemical insecticide that inhibits eggs hatching and life cycles of Ae. aegypti.

Abstract

Aphids (Hemiptera: Aphididae) are considered as one the most important pest in the world. Some species of aphids were reported as serious pests and plant virus vectors, especially on horticultural crops. Weeds in the agricultural area can serve as an alternative hosts for some aphids which are plant pests or plant virus vectors. The objective of this research was to identify aphid species of weeds in the agricultural production area in West Java and to provide the identification key. Aphids collection was done on the weeds in the agricultural fields in 9 districts of West Java. Aphids were collected from 13 species (5 families) of weeds. The identification of aphid was peformed based on the adult specimens. The research manased to come up with 12 species of aphid on weeds. Three of the 12 collected species were Epameibaphis frigidae (Oestlund), Metopolophium dirhodum (Walker), and Pseudaphis sijui (Eastop) has never been reported in West Java. Six species were known as vectors of plant viruses in agricultural crops. The most commonly found aphid species was Schizaphis graminum (Rondani) in the yard grass (Eleusine indica).

Abstract

Brown planthopper (Nilaparvata lugens Stí¥l) population from Klaten and Yogyakarta may develop into new biotype, but research on the genetic aspect of these populations is limited.  Random amplified polymorphic DNA (RAPD)-PCR technique was used to identify the genetic similarity of brown planthopper population from Klaten and Yogyakarta compared to the population of nearby region. Brown planthopper were collected from paddy field in Klaten, Yogyakarta, Sukoharjo, Boyolali, Karanganyar, Sragen, and Ngawi. Five random primers, namely OPB 01, OPB 07, OPC 04, OPC 08, and OPN 15 were used to amplify the brown planthopper. The present study revealed that five random primers produced DNA band patterns clearly and comparable. However, no primer produced DNA band that could differentiate the brown planthopper population from Klaten and Yogyakarta compare to the population from nearby region. Based on dendrogram, the population from Klaten and Yogyakarta showed a genetic similarity to the nearby population from Sukoharjo, Boyolali and Sragen, except from Karanganyar and Ngawi. Intra-population genetic studies of brown planthopper from Klaten and Yogyakarta may be needed to reveal more genetic characters.

Abstract

Papaya mealybug, Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae), is an invasive pest that was detected for the first time in Indonesia in 2008. One of the common natural enemies is the predatory beetle Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae). The research was conducted with the objectives to determine the biology, life table parameters, and predation of C. montrouzieri on P. marginatus. Observation of biological and life table parameters and predation was conducted by introducing the predators into Petri dishes containing mealybugs. Eggs of C. montrouzieri hatched in 4.35 days. Mean developmental periods for 1st, 2nd, 3rd, and 4th instar larvae were 4.23; 4.21; 5.84; 5.93 days, respectively. The mean pre-pupal and pupal periods were 1.95 and 7.55 days, respectively. The longevity of male adults was 51.34 days, while that of females was 83.39 days. The number of eggs laid by a single female averaged 198.49. The net reproductive rate (Ro) was 117.11 individu/female/generation, intrinsic rate of increase (rm) was 0.073 individu/female/day, mean generation time (T) was 64.776 days, doubling time (Dt) was 9.426 days, and finite rate of increase (λ) was 1.076 per day.  The 4th instar larvae of C. montrouzieri was the most voracious with numbers of P. marginatus eggs, 1st, 2nd, 3rd instar nymphs or adults consumed were 188.0; 53.4; 44.0; 26.8; or 15.6; respectively. Manly's preference index suggested that larvae, as well as adults of C. montrouzieri, preferred eggs and 1st instar nymphs of P. marginatus over other mealybug stages. Our study indicates the high potential of C. montrouzieri in the biological control of P. marginatus.

Abstract

Parasitoid Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) was introduced from Thailand into Indonesia in early 2014 to control the invasive cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). Research was conducted in laboratory with the objectives to determine effect of honey on adult longevity, to study fecundity, progeny production, and sex ratio, and to evaluate effect of increased host density to parasitization. Studies were carried out by exposing 3rd instar nymphs of mealybug to parasitoids. Effect of honey on adult longevity was done in the absence of hosts. Fecundity was measured by the number of mummies formed. Results showed that adult females lived for 3.7 days, while males lived for 3.2 days when only provided water. Adult longevity increased significantly when honey was provided. Parasitoids with access to 50% honey lived almost six to nine fold longer than those provided water. Over its adult life, A. lopezi parasitized 96–287 mealybugs with an average of 203.7 or 34.6% of hosts were parasitized, and 24.86% were killed through host feeding. Development from egg to adult emergence required 17.97 and 17.67 days for males and females respectively. The average number of offspring produced per female was 88.8 individuals, of which 56.9% were females. The number of hosts parasitized at densities varying from 2–100 cassava mealybugs corresponded to a type III functional response.

Abstract

Oriensubulitermes inanis (Haviland) is one of the endemic termites in the Oriental Region and plays a very important role in the decomposition process in tropical forests. This study aims to redescribe O. inanis from Indonesia. Termite were collected by adopting a Standized Sampling Protocol (Jones & Eggketon 2000) and final taxonomic confirmation were conducted at the Natural History Museum UK) and Florida University (USA). We found 21 colonies of O. inanis from various habitats and altitudes in Indonesia. Distribution of O. inanis is often correlated with biodiversity status in tropical forests. Worker caste mandible provides the most useful character for the description of O. inanis. In Southeast Asia, this rare species is restricted and can be found only in the Malay Peninsula, Borneo and Sumatra, and absence from Java. Decayed wood, base of tree trunks, and other termite nests (epigeal mounds) are selected media used to construct their nests. Limited population number in a colony, restricted alates flying ability, and secretive nest habitats are thought to influence the distribution of O. inanis in Indonesia.

Abstract

Lac insect (Laccifer lacca Kerr) (Homoptera: Kerriidae) is an insect species that attack various plant species and produce lac as a by-product. The insects produce compact and thick natural resin and attached to the branch commonly called shellac. Branch lac is a natural resin from the secretion process of insects named L. lacca in the form of a thick-layered lac that covering the branches of the host plant. Parasitoids and predators attack lac insect has a direct impact on the decrease in shellac productivity. The aim of the research is to determine the dynamics of parasitoid populations on lac insect, the diversity of parasitoids and predators attacking lac insect, identification parasitoids and predators that attack to lac insect, measuring parasitization level in BKPH Kabuaran and Taman, KPH Probolinggo, Perum Perhutani Unit II - East Java. Samples branch lac of BKPH Kabuaran and Taman each of 200 lac branch was collected. The dominant families of parasitoids found are Aphelinidae, Encyrtidae, and Eulophidae. Predators found to consist of Family Lathridiidae (Coleoptera), Cosmopterigidae and Noctuidae (Lepidoptera), Nabidae (Hemiptera), and Chrysopidae (Neuroptera). The cumulative amount of parasitoids in the field is more high (5.900 individuals) than in warehouses (5.263 individuals). The highest increase of individual parasitoids in the field and warehouses occurred at the observation day 7th to 17th. The parasitization level of lac insect in the field and warehouse was high i.e., 93% and 96% respectively. It can be concluded that lac insect from both the field and werehouse are alike parasitized.

Abstract

Chili peppers (Capsicum annuum), in their many varieties, constitute a culturally and economically important horticultural crop in a number of countries. The Indonesian cayenne large red chili (Capsicum annuum var. annuum) is used widely in Indonesia mainly in cooking. There have been reports of increased infestation of large red chili by insect pests, particularly fruit flies. The aim of this study was to investigate the effectiveness of five edible vegetable oils (palm oil, coconut oil, soybean oil, corn oil, and candlenut oil) and one non-edible vegetable oil (neem oil) in reducing landings, oviposition, and infestation by the Oriental fruit fly (Bactrocera dorsalis Hendel) in large red chili fruits. This lab-based experiment entailed exposure of large red chili fruits to 20 mature B. dorsalis females (14–21 days old) inside a 15-l plastic container. Six separate containers each held 10 large red chili fruits with a single oil treatment in each. Prior to exposure, each of the treated and control large red chili fruits was punctured once with a needle in order to create an opening for oviposition. Results indicate that the coconut oil formulation was most effective in preventing damage from B. dorsalis females, and reducing fruit fly landings, oviposition, and infestation.

Abstract

Elaeidobius kamerunicus Faust is an oil palm pollinator insect that lives on the male inflorescence and visits female inflorescence to pollinate due to attracted by its volatile compound. The number of fruit sets of oil palm relates to the population of E. kamerunicus on a plantation. The objective of this study was to investigate the effect of age of oil palm on the population of E. kamerunicus. Field research was conducted in oil palm plantations that located in Pangkalan Lada, Kotawaringin Barat District, in Central Kalimantan. The research method was by measurement of E. camerunicus population on male inflorescences and set up the sticky trap on female inflorescences. Plot with size 7000 m2 (100 trees) was selected on several ages of oil palm i.e. 6, 10 and 16 years. Each plot, the number of male and female inflorescences was counted and some inflorescences were chosen for measurement of E. camerunicus population that was conducted monthly for three months of observation. The results showed that the age of the oil palm affected the population of E. kamerunicus in male inflorescences but not in female inflorescences. The older age of oil palm, the population of E. kamerunicus in male flowers was increasing. The sex ratio of E. kamerunicus found in male and female inflorescences of oil palms tend to female bias. Based on the comparison of E. kamerunicus population between male and female inflorescences on each plot, it was found that visitation value of E. kamerunicus was highest in the young oil palm. In conclusion, increasing age of oil palm trees affected on increasing of E. kamerunicus population in male inflorescences, but visitation value on female inflorescences prone to decline.
