Abstract

Vanilla is one of spice crops and important to world commerce. Indonesia is one of producing and exporting countries for decades. Recently, the planted area tends to decrease due to several factors. One of them is fusarium wilt caused by Fusarium oxysporum fsp. vanillae. The disease ranked among the most devastating disease attacking vanilla plants. The most effective method controlling fusarium wilt is the use of resistant varieties. The study aimed to know responses of vanilla plantlets irradiated by Gamma rays at several doses (0-4 krad). Five months after irradiation, the survival mutant plantlets were inoculated with suspension of the F. oxysporum fsp. vanillae to evaluate their resistance. Data of first concern taken were survival plantlets; number of leave, root, and sucker initiation; and infection intensity. The results indicated that higher the doses, decreased the survival plantlets. The applied doses performed significantly differences on the number of leave, root, and suckerinitiation. The untreated plantlets showed better responses as compared to those treated. Evaluation on their resistance after inoculation indicated that the survival plantlets irradiated at 3 and 1 krad showed lower infection intensity, eventhough variation within a treatment was observed. Evaluation on the individual plantlet basis seemed to be more helpful in order to identify mutant plantlets with better resistance.

Abstract

The objective of this research was to know the resistance level of beet armyworm Spodoptera exigua to methoxyfenozide. The lara were collected from the shallot production areas in the districts of Nganjuk (East Java), Bantul and Kulonprogo (Yogyakarta Specia Territory) and Brebes (Central JAva). The bioassay used first instars of S. exigua with artificial diets that had been dipped in a series of methoxyfenozide solutions. Larval mortality was recorded at 72 hours after the exposure. The LC50 value of methoxyfenozide for the population from Sanden (Bantul) was the lowest (0.53 ppm) among 16 tested population, therefore it was used as refenrence population to determine the resistance ratio (RR) values of other populations. The RR values of the tested populations varied from 1 to 240,8 times. Population collected from Wanasari (Brebes) was found to have the highest level of resistance of methoxyfenozide as a result of using methoxyfenozide intensively to S. exigua controlling.

Abstract

The use of chemical insecticide in crop protection around the world has resulted in disturbances of the environment. Therefore, it is necessary to develop for environmentally friendly insect pest management techniques such as the activity of liquid smoke made from tobacco stem waste as an insecticide to Spodoptera litura. Activity of liquid smoke of tobacco stem waste was carried out at the laboratory condition. The results showed that the application of liquid smoke by using the spraying method (direct method) showed better results compared to the results of feeding method (indirect method). Lethal concentration (LC) at 5 days after treatment, LC50 and LC75 values the direct method of 2.9% and 8.87%, while the indirect method of 6,99% and 21.03%. The sub lethal concentration did not cause mortality of S. litura larvae, but inhibited the growth such as indicated by lower weight of larval and pupal in treated larvae than in control. Liquid smoke of tobacco stem waste has activity as an insecticide to S. litura. INTISARIPenggunaan pestisida kimia dalam pengendalian hama di dunia telah menimbulkan gangguan terhadap lingkungan. Maka teknik pengendalian hama yang ramah lingkungan perlu dikembangkan, misalnya aktivitas asap cair limbah batang tembakau sebagai insektisida pada Spodoptera litura. Aktivitas asap cair limbah batang tembakau dilakukan pada kondisi laboratorium. Hasil penelitian menunjukkan bahwa aplikasi asap cair secara langsung (metode semprot) lebih efektif daripada tidak langsung (metode celup pakan). Lethal concentration (LC) pada 5 hari setelah perlakuan, LC50 dan LC75 pada aplikasi langsung sebesar 2,9% dan 8,87%, sedangkan pada aplikasi tidak langsung 6,99% dan 21,03%. Konsentrasi subletal tidak menyebabkan kematian S. litura tetapi mampu menghambat pertumbuhan yang diindikasikan dengan rendahnya bobot larva dan pupa S. litura. Asap cair limbah batang tembakau bersifat insektisida terhadap larva S. litura.

Abstract

A field population of Plutella xylostella (Lepidoptera: Plutellidae) in Central Java has been reported to become resistant to a pyretroid synthetic deltamethrin. The objective of this research was to study the genetics of resistance in that population. The resistant population wascontinously sprayed with deltamethrin in the laboratory to increase the resistant level. The resistant population used in this study was 51 more resistant to deltamethrin than was the susceptible population. Bioassays using F1 obtaining from the reciprocal mating between the susceptible and resistant parents showed that the resistance to deltamethrin in P. xylostella was inherited recessively and the maternal effects were observed. The degree of dominance (D) was -0.8 when resistant female was mated with the susceptible male and the D value was -0.3 when the susceptible female was mated with the resistant male. Using the monogenic model it was proved that the resistance was controlled by single gen. The implementation of these findings for the development of resistance management program will be discussed.

Abstract

Banana bunchy top disease (BBTD) can be caused by the infection of two different viruses, Banana bunchy top virus (BBTV) or Abaca bunchy top virus (ABTV). Both viruses can be transmitted persistently by aphid Pentalonia nigronervosa Coq. The research was conducted to detect and to differentiate the virus bypolymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) techniques. Infected plants were collected from Yogyakarta (Sleman, Yogyakarta city, Bantul, Gunung Kidul, and KulonProgo). Nucleon Phytopure DNA Extraction Kit method was used to extract the total DNA of infected plants. Universal primers of Common DNA region (S-CRF and S-CRR) and specific primers DNA-R (C1-CRF and CI-CRR) were used for PCR amplification. PCR products were analyzed by RFLP technique using the restriction enzyme of DraI. The results reconfirm previous reports that bunchy top disease of banana in Yogyakarta is caused by BBTV. The ABTV was not detected in this present study. Based on the RFLP analysis it was concluded that BBTV collected in this study could be divided into three groups. Group 1 consisted of BBTV isolate from Sleman and Yogyakarta city with two fragments DNA of 400 and 388 bp. Group 2 consisted of isolate BBTV from Kulon Progo and Gunung Kidul with three fragments DNA of 400, 388, and 323 bp. Group 3 consisted of isolate from Bantul with two fragments DNA of 723 and 376 bp. Further study on the complete characteristics of these groups is still needed.

Abstract

Diapause of larvae of the white stem borers, Scirpophaga innotata (Walker), is interesting and can be terminated by exposing them in a certain low thermoperiod, so that the brain is activated to initiate the production of prothoracotropic hormone (PITH). In this case water is strongly suggested responsible for stabilizing this low thermoperiod by mechanism of buffering (capture and release) heat.

Abstract

Pepper yellow leaf culr disease has been widely spreading in Indonesia, especially in Special Province of Yogyakarta and Central Java since 2000. The disease is difficult to control because its fast spreading over in the field by the vector. To prevent epidemic of the disease, early detection method of the causal agent is needed. The aim of the research was to detect the causal agent of the pepper yellow leaf curl disease by isolating the DNA genome. Using the Guanidine-alkaline method, two specific fragments of the DNA were produced approximately at 2600 bp and 1600 bp. The DNA fragments were similar with the DNA genome of Begomovirus. The method applied in this study is faster and easier for early detection of the Begomovirus in infected crop than detection by the Polymerase chain reaction (PCR).
