Abstract

The occurrence of ants in agricultural habitat is related to the availability of food resources as well as environmental condition for its nesting site. As predator, ants play an important role on controlling pest population in agricultural habitat. The objective of this research was to study the diversity of ants in pepper plantation. The research outcome can be used as basic information for cultivation management of pepper. Ecological observation was conducted in four regencies in Lampung Province with two selected plots on each regency. On each plot, ants were sampled using pitfall traps. In total, 28 ant species were recorded from pepper field in four regencies. Two species i.e. Anoplolepis gracilipes and Solenopsis geminataare well-known as tramp and invasive species. There is significantly different of ant species composition among regencies. The occurrence of ants in pepper plantationis probably affected by habitat condition surrounding pepper plantation and precipitation.

Abstract

Aphis craccivora is one of the important pests on yard long bean. It causes direct damage and also has an indirect effect as insect vector of the Bean common mosaic virus (BCMV). The research was done to test the effectiveness of chitosan in suppressing aphid population growth, feeding preference and its ability in transmiting BCMV. Chitosan with concentration ranging of 0.1–1.0% were applied on leaves using spraying method at 1 day before BCMV transmission. BCMV was transmitted by using 3 individuals of viruliferous aphids on each plant. Results show that chitosan treatments on leaves or plants significantly suppressed the population and feeding preferences of A. craccivora. Further, treated plants showed lower disease incidence, severity and BCMV titre significantly compared with untreated control plants. The positive effects of chitosan in suppressing population growth as feeding preferences and BCMV transmission might be due to the anti-feedant effect of chitosan on A. craccivora. Based on the result, chitosan at concentration 0.9% is the most effective concentration in suppressing BCMV and its vector A. craccivora.

Abstract

Asian corn borer, Ostrinia furnacalis Guenée, is known as an important pest of maize, Zea mays L., in both whorl and reproductive stages. Management decisions based on egg-mass density is useful because decision is made before damage occurs. Observation on O. furnacalis egg-mass distribution in maize-field was carried out in Agricultural Training, Research, and Development Station (ATRD) UGM, Yogyakarta. The number of egg-masses laid on each plant surface in maize-field was sampled in reproductive stage of corn at 52 – 58 days after planting. The spatial dispersion was analyzed using the ratio variance-to-mean (σ2/μ = Iδ), Morista's Index (Iγ), and the negative binomial parameter (κ-value). The results showed that horizontal and vertical distributions were aggregated distributions (σ2 > μ or σ2/μ > 1). In line with the increasing age of plant, the degree of clustering or aggregation likely tended to decline (the κ-value increased, Morisita index decreased) indicating the possible departure from aggregation to randomness (Poison distribution) due to the heterogeneity of the environment, such as microclimate, preferred parts of the plants, and occurrence of natural enemies. The results concluded that the horizontal and vertical distributions of egg-masses of O. furnacalis on corn in generative phase were clustered with the degree of clustering tended to decrease by the increase of age of corn. These findings provide the bases for further study on the ecology and biology of O. furnacalis for management decision-making process.

Abstract

Plant damages caused by leafhopper, Empoasca terminalis Distant (Homoptera: Cicadellidae) on soybean were first encountered in 2007 in Makassar, South Sulawesi. The insect has been constantly associated with soybean crops in the province ever since. The purposes of the present study were to (i) evaluate potential yield loss attributable to the leafhopper in an experimental set up, (ii) seasonal abundance of E. terminalis, and (iii) distribution of E. terminalis in all major soybean-producing areas in the province. Potential yield loss due to the leafhopper was assessed in a field experiment using two large plots. One of the plots was kept leafhopper-free by weekly insecticide sprays; and the other plot was left unsprayed to allow leafhopper infestation to occur. Adult abundance was weekly monitored using a sweep net throughout the season. Nymph abundance was determined by direct count on the plant leaves. Leafhopper distribution was assessed through surveys conducted in all major soybean-producing areas in South Sulawesi, from 2009–2013. The results of the study showed that E. terminalis caused an average yield loss of 26% on susceptible crops without insecticide use. First leafhopper infestation in all planting seasons occurred two weeks after the plant emergence. Rainfall negatively correlated with the leafhopper abundance. The leafhopper existed in all major soybean production areas in the province. Therefore, our results confirmed the status of E. terminalis as an important soybean pest in the region. In addition, crops planted early in the dry season could escape from heavy leafhopper infestation.

Abstract

The condition of agroecosystem may affect the diversity and effectiveness of parasitoid communities as natural enemies of insect pests. Agricultural intensification such as monoculture cultivation as well as application of insecticide could also cause declining to parasitoid diversity and ineffective performance of parasitoids in agricultural field. The objective of this research was to study trophic interaction between pests and parasitoids in different field of vegetable crops and to investigate the factors that determining those interactions as well as its implication on parasitoid effectiveness. Vegetable crop fields were grouped into three different categories i.e. based on the pattern of cultivation, diversity of vegetable crops around the field and age of plant. On each crop field, insects were sampled using 50 m of transect by collecting eggs, larvae and pupae of pests. In total, 15 species of pests and 15 species of parasitoids were recorded from eight species of vegetable crops. Based on the analysis, trophic interaction between pests and parasitoids were affected by cultivation system, condition of crop field (species diversity of crops in its surrounding) and age of vegetable plants. Although it was not significance, the effectiveness of parasitoids according to their parasitism level, tend to higher in trophic interaction that determined from crop field with organic systems and with diverse of crop plants.

Abstract

Rice stem borer abundance are largely influenced by climate. This research aims to (i) develop a population dynamic model of yellow stem borer (YSB) and (ii) to assess the model's ability to predict abundance and population peak of YSB under climate change scenario SRES A1FI and B1. Modeling the YSB requires two major components: climate parameter and lower developmental threshold temperatures (To) to describe life cycle of YSB from the egg, larva, pupa, and adult stages. The research utilized DYMEX software to describe development, mortality, transfer of individuals from one to the next life stages, fecundity and reproduction of YSB. The coefficient of determination (R2) of calibration models between predictions and observations showed a strong positive correlation of 0.65. Model validation could well predict the peak population, with R2 = 0.42. The simulations showed that the trend of population peak occur at high rainfall i.e. in March to April, July to September, and November to December. The model predicted YSB population in the Sukamandi reaches 3 generations per year, while in Kuningan 2 generations per year. Simulation models under climate change scenarios SRES A1FI and B1 showed differences in the sensitivities. Trend of YSB population is increasing in the regions Kuningan and decreasing in region Sukamandi. Under changing climate, environment conditions in Kuningan become more suitable for the proliferation of YSB, allowing an increase in the number of generations per year.

Abstract

Bemisia tabaci (Gennadius) is an important pest on horticultural crops that can also become a vector of Geminivirus that transmit the yellow curl disease. B. tabaci can also attack weeds that grow around the field such as Ageratum conyzoides or goatweed. The objective of this research was to study the life cycle, life time, fecundity, and reproduction rate of B. tabaci on chili pepper and goatweed. The experiment was conducted by observing the development of 50 eggs into adulthood. All 50 eggs were put on one plant and repeated 3 times. The plants were grown at temperatures 25 °C and 29 °C inside growth chamber (L : D = 12 : 12). The result of this experiments showed that at both temperatures of 25 °C and 29 °C, reproductive rate (R0), intrinsic rate of increase (r) and fecundity of B. tabaci were higher on goatweed than chili pepper. This implies that the existence of goatweed around chili pepper in the field can serve as a good alternative host for B. tabaci, hereby supporting the pest population even further.

Abstract

The Asian corn borer, Ostrinia furnacalis (Guenée) is an important economic pest of corn and is widely distributed in the Asia-Pacific region, including Indonesia. The objective of this research is to investigate the effect of infestation levels of O. furnacalis larvae per plant on corn grain yield reductions, and to determine economic injury levels (EIL) of O. furnacalis larvae at three growth stages (V10, R1, and R2) of corn. The experiment was designed in a split-plot randomized complete block with blocks replicated three times. Differences in grain weight between the uninfested and highest infestation levels (six larvae per plant) V10, R1, and R2 were 59.81; 58.76; and 49.20 g/plant, respectively. For each additional infestation by one larvae per plant at V10, R1, dan R2, there is reduction in grain weight of 4.94%, 4.56% and 3.76% respectively. The calculation of EILs was based on the proportion of yield loss per larvae per plant on three corn growth stages with the assumption that pesticide control reduced 67% of O. furnacalis population. The lowest EIL was 0.31 larvae per plant at V10 when the cost of control reaching Rp.125,000 per ha and crop value of Rp.12,000,000 per ha. The highest EIL of 1.24 larvae per plant was found at R2 with the cost of control of Rp.250,000 per ha and crop value of Rp.8,000,000 per ha.

Abstract

Anagrus nilaparvatae Pang et Wang (Hymenoptera: Mymaridae) is a major egg parasitoid of brown planthopper, Nilaparvata lugens Stal (Hemiptera: Delphacidae). The purpose of this study was to examine the egg development type, the effect of host deprivation and feeding on the reproductive performance of parasitoid. Determination of the egg development type was done by dissecting females of A. nilaparvatae upon emerging. Adult females aged 0, 1, 2, 3, 4, 5, and 6 hours were killed in the freezer. Abdominal of wasp was dissected by micro pin. Mature egg of wasp were calculated and documented. Treatment of host deprivations were conducted by feeding 10% honey solution and depriving female parasitoids of host for 3, 6, 9, 12, and 18 hours consecutively. After treatments, female parasitoids were given hosts every day until the parasitoids died. Another group of parasitoids were given with water and treated with the same lenght of deprivation period. Results showed that the A. nilaparvatae egg development type is proovigenic. The egg maturation of parasitoid has been initiated since it first emerge with 75% mature eggs of potential fecundity. In the conditions provided 10% honey solution or water as feed, reproductive performance of A. nilaparvatae decreased with increasing duration of host deprivation period, include realized fecundity, parasitization rate, and longevity of female wasp. The decline in the reproductive performance was done by host deprivation for 9 to 18 hours. Longevity of female wasps varied from one to three days, with higher and lower values consecutively for 9 and 18 hours of host deprivation period.

Abstract

Termite, is one of the most damaging pest for wood product. One of the common fumigant use to control termite is sulfuryl fluoride. The objective of this study were to determine the dose-exposure and time for sulfuryl fluoride to kill dry wood termite Cryptotermes cynocephalus Kemner and evaluate the ability of fumigant to penetrate a rubber wood block. Application and penetration of the fumigant was tested on a 10 cm depth wood block, and conducted with 5 varied doses (10−30 g/m3) and 4 varied exposure time (6−24 hours). Application of the fumigant were tested on an 5 and 2.5 cm depth wood block. Doses were applied using 4 (four) different doses (2−15 g/m3) and 4 varied exposure time (1−9 hours). The study was conducted using randomize completely design with factorials. Results showed the application of sulfuryl fluoride was effective in penetrate 10 cm depth of wood block. The dose that was effective was of 30 g/m3 with 18 hours exposure time or a dose of 15 g/m3 with 24 hours exposure time. Application of depth penetration of 5 cm effectively done by using a dose of 10 g/m3 with 9 hours exposure and depth penetration of 2.5 cm using a dose of 15 g/m3 with 6 hours exposure time. Dose-time relationship for application of sulfuryl fluoride to penetrate of 10 cm showed dose variable is a slightly more important than exposure time, while to penetration of 5 and 2.5 cm showed exposure time variable is a slightly more important than dose of fumigant.
