Abstract

Phytophthora palmivora, is a deadly pathogen of duku, causing serious problem in the main production area, especially in Jambi Province, Indonesia. The pathogen can infect duku plant in all stage of growth including seedlings. Organic amended media might become a potential alternative option for this disease management. These studies were performed in soil media containing organic fertilizer of 0%, 10%, 20%, 30% (v/v), served as treatment, and subjected to completely randomized design with 5 replications. This research found that incorporating 20% of organic fertilizer into media was able to lower disease severity by 23%. The ability of organic fertilizer to increase media bacterial and maintain fungal density and increase chemicals of C-org, P, K, Ca, Mg and Zn played important roles in reducing disease development.

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.

Abstract

Eucalyptus (Eucalyptus spp.) is a fast-growing tree native in Australia, Papua, and Eastern part of Indonesia. It is valued for its timber, oil, gum, and resin, and as an ornamental tree. Many eucalyptus clones have been developed and planted for timber production in Sumatera. Several galls caused by insects are known as serious pests of eucalyptus and can reduce the quality and quantity of the timber production. This study was aimed to identify the gall inducers and describe the galls that formed on the eucalyptus clones which planted in Mt. Mutis, East Nusa Tenggara Province. The research was conducted from October 2017 to July 2018. A total of 855 seedlings consisting of 57 clones and 15 plants for each clone were planted in Mt. Mutis. Observations of the gall symptoms were done biweekly on each plant. Gall symptoms were directly observed and identified, included the form, size, location, color, and insect that caused the gall. There were four types of gall forms were recorded. One type of gall caused by Ophelimus sp. (Hymenoptera: Eulophidae) which similar to the gall recorded in Sumatera and Java. The other three gall forms were never been reported in Indonesia. The insects that associated with galls were Hymenoptera and Diptera orders. The type of gall that mostly found in the eucalyptus clones was the big clustered leaf gall caused by Fergusonina sp. (Diptera:  Fergusoninidae).  There are only two clones which are included as susceptible clones based on the type of gall formed, C35 and C53. There were 27 eucalyptus clones with no gall infestations which were considered as the good candidate of resistance eucalyptus clones to the gall infestations.

Abstract

Mango pulp weevil (MPW) and mango seed weevil (MSW) are found in only three species in the world, namely Sternochetus frigidus (MPW), Sternochetus mangiferae (MSW) and Sternochetus olivieri (MSW). These pests are the main pests for mango in several countries including Indonesia. But there is currently no report on the status of the three insects of Sternochetus in Indonesia, so that the information received by the Center for Agriculture and Biosciences International (CABI) as a worldwide plant pest data center is based on Kalshoven (1981). The purpose of this study was to identify species, to test the attack level and to conduct no-choice test on Sternochetus host in mango. This study was conducted at the Applied Research Institute of Agriculture Quarantine from March to October 2017. Kuweni fruit (Mangifera odorata) that was confirmed to be infested by Sternochetus insect was collected from Pesisir selatan District of West Sumatra, North Lampung District, Lubuk Linggau District of South Sumatera and Bekasi District of West Java Provinces respectively. The species identification was performed on the male genital (aedeagus) of the insect, which was obtained from the Kuweni fruit aged 95-115 days. The fruit collection from the three locations have identified S. frigidus species, with overlapping apical sclerite characteristics. In Bekasi District, S. frigidus insect could not infest the Kuweni fruit. Attack level test of S. frigidus in kuweni fruit in all three locations reached 93%. The result of host status test with no choice test showed that S. frigidus was able to infest harum manis and manalagi mango (Mangifera indica) and did not infest sapodilla fruit.

Abstract

Status of Infestation and Biology of Pepper Fruit Fly, Atherigona orientalis (Schiner) (Diptera: Muscidae). Numerous muscid flies Atherigona orientalis (Schiner) (Diptera: Muscidae) emerged from fruitfly-infested pepper fruits. It is not known whether A. orientalis is primary or secondary pest, and its biology is poorly studied.  Research was conducted with the objectives to determine the status of infestation of A. orientalis on pepper fruits, and to study its biology. Field survey was conducted in pepper fields in Bogor, whereas study on its biology was done in laboratory. Field surveys showed that flies emerged from fruitfly-infested fruits consisted of 86.1% A. orientalis, 4.8% Bactrocera dorsalis, and 9.1% other fly species.  Fruits having only A. orientalis representing 79.7% of the infested fruits. Number of A. orientalis flies emerged per fruit ranged 1-24, with an average of 3.5 individuals. Laboratory study showed incubation period of eggs was 1.62 d, larva development lasted 11.93 d, and pupa 5.08 d.  Longevity of female adult was 32.85 d and male 31.40 d. Number of eggs laid by a single female ranged 12-191, with an average of 83.80. Net reproductive rate R0 =36.052, intrinsic rate of increase rm = 0.136, mean generation time T = 26.482, doubling time Dt = 5.098, and finite rate of increase ? = 1.145. Overall, our research indicated that A. orientalis was a primary pest of pepper fruits, with a high potential of population increase.

Abstract

Detection and Transmission of  rice stunt virus on Ciherang and Situ Bagendit Varieties. The explosion of brown planthoppers recently has caused reduction of rice production in Indonesia. Brown planthoppers do not only act as pest, but also transmit Rice grassy stunt virus (RGSV) and Rice ragged stunt virus (RRSV). Detection of the existence of the two viruses in rice plants and vector insects is important to be done to ensure that the virus is infected with the vector. The aim of this research is to detect the existence of virus in varieties of Ciherang and Situ Bagendit as a result of transmission in the laboratory and to find out the ability of brown planthoppers to transmit stunt virus to both of the varieties. This research was compiled using Completely Randomized Design (CRD) with 4 treatments, namely healthy rice plants of Ciherang and Situ Bagendit varieties, Ciherang and Situ Bagendit varieties which were infested by brown planthoppers each with 5 repetitions. The parameters observed were incubation period, symptoms, plant height, number of leaves and incidence of disease. The data on plant height, number of leaves and incidence of disease were analyzed using ANOVA and continued with the Least Significant Difference (LSD) test at the level of 5%. The results showed that Ciherang and Situ Bagendit varieties were only positively infected by Rice ragged stunt virus. The results of the rice transmission showed that Ciherang variety had a faster incubation period of 10 DAI while Situ Bagendit was 14 DAI, but the two varieties showed an inhibition of growth in plant height and number of leaves compared to healthy plants with each incidence of 51.3% and 46.3%.

Abstract

Laboratory bioassays were conducted to compare the effects of the leaf extract of Acalypha indica  L. (Euphorbiaceae) with synthetic insect growth regulators (IGRs) triflumuron and buprofezin against Spodoptera litura (F.). The experiment was set up as a randomized complete block design (RCBD). The treatments were two concentrations of  A. indica extracts 1000 and 2000 ppm, two concentrations of  buprofezin 100 and 200 ppm, two  concentrations of triflumuron 120 and 240 ppm and control. Each treatment was replicated three times. Second instar larva of  S. litura  were used for the bioassays.  Mortality and biological variables of treated and control larvae were recorded daily. The results indicated that the application of A. indica extracts  and synthetic IGRs (buprofezin & triflumuron) significantly caused the S. litura  mortality throughout the experimental period. At first, the toxicity of triflumuron on larval S. litura was significantly higher compared to those of buprofezin and Acalypha indica leaf extract. However, at the end of experimental period all treatments caused high mortality on S. litura, and those all were significantly different from control. The treatments also caused abnorrmal growth in larval, pupal, and adult stages. While in the control, larvae molted into normal adults. The results indicated that the use of biorational control agents such as synthetic insect growth regulators (IGRs) and those based on naturally derived products such as botanical insecticides show promise as a potential tool in S. litura management programs.
