STRATEGI PENGENDALIAN DAN PENGELOLAAN HAMA KUMBANG BUBUK (Sitophilus zeamais Motsch) (Coleoptera: Curculionidae) PADA TANAMAN JAGUNG MENUNJANG STABILITAS PRODUKSI DAN KETERSEDIAAN PANGAN NAIONAL (AARD Press 2016).

Hama kumbang bubuk (Sitophilus zeamais Motsch) adalah hama gudang pada tanaman jagung yang dapat menyerang biji jagung sejak di pertanaman khususnya pada tanaman jagung yang mempunyai penutupan klobot yang tidak sempurna hingga pada saat biji jagung berada pada periode penyimpanan. Populasi hama ini dapat meningkat seiiring dengan lamanya penyimpanan. Kerusakan yang ditimbulkan sangat besar, data referensi menunjukkan bahwa tingkat kerusakan rata-rata yang diakibatkan oleh serangan hama ini dapat mencapai angka 30%. Berkaitan dengan hal tersebut, maka beberapa kajian penelitian dalam rangka penanganan dan pengelolaan hama ini ditampilkan dalam bentuk sitasi dan kutipan yang dimaksudkan untuk memberi informasi dan perbandingan tentang mekanisme kajian riset yang telah ada sebelumnya.

Abstract

Development of Brown Planthopper, Nilaparvata lugens Stal Population and Its Predators at Different Cultural Techniques of Rice Production.  An experiment was conducted in irrigated rice field with a rice-rice cropping pattern in Pemalang district 1995/1996 planting season. The objective was to select a cultural technique that could stabilize brown planthopper (BPH) population. The experiment used a sub-sample design with a two-stage sampling method and a visual observation method of insect population. There were four treatment combinations of planting time (simultaneous and unsimultaneous) and insecticide (with and without insecticide application). Results indicated that during the planting season, the BPH population was relatively stable and fluctuated at a low level, i.e 3.1 - 10.5 hoppers/15 hills, and the predator population fluctuated at a high level, i.e. 9.8 - 23.1 predators/15 hills). At unsimultaneous planting time and without insecticide application, BPH and predator population were higher than those at simultaneous planting time and with insecticide application. At unsimultaneous planting time, the BPH population just before harvest was significantly increased. Therefore, it was suspected that the population would explode in the next planting season. It was concluded that the cultural technique with a combination of simultaneous planting time and without insecticide application was suitable to be applied at the time and location or the experiment. The insecticide application, especially at an unsimultaneous planting time, decreased farmer income and gave opportunity to BPH to explode.

ABSTRAK

Penelitian pembiakan dengan makanan buatan untuk penyediaan serangga inang dan patogenisitas NPV (nuclear-polyhedrosis virus) terhadap Leucania separata telah dilakukan di Balai Penelitian Tanaman Pangan Bogor. Makanan buatan untuk pembiakan ulat L. separata diuji dengan membandingkan beberapa sifat biologi ulat tersebut pada beberapa tanaman inangnya. Patogenisitas NPV diuji pada berbagai umur ulat L. separata.
Ulat L. separata dapat dibiakkan dengan makanan buatan. Sifat biologinya sama dengan ulat yang dibiakkan dengan tanaman inangnya. Ulat instar 1 sampai 3 lebih rentan terhadap NPV daripada ulat instar 4 dan 5. Ulat instar 5 menunjukkan ketahanan 100 kali lebih besar daripada ulat instar 1.

ABSTRACT

Pest becomes one of productivity handicap in the field of irrigated rice plantation. One type of the potential pest with its sudden attack and often cause a yield failure is the larvae of Mythimna separata (Lepidoptera: Noctuidae) which are called armyworm (ulat grayak). The aims of this research are 1) to determine the stage rice plant destruction due to the larvae attack, 2) to determine the rice yield loss due to the attack, 3) to obtain an integrated pest control packet for rice plant, like: a) economic threshold for the pest larvae, b) the loss of economical yield to becomes in basis making a decision to control the pest larvae. This research was conducted at the greenhouse of Balitpa, at Bogor on April 2001 and at the yield station (1500 m2) at the area of Indramayu, West Java, starting at the dry season on June 2001. Paddy variety involved is IR64 with a planting period of 30.45 and 60 days after transplanting. Larvae density treatment is 0; 1; 2; 3 and 4 larvae of 3rd instar per hill. Replication taken is 3 times at the field and 4 times at the greenhouse. Experiment done are using random group program which is factorial designed with 2 factors (larvae density and plant age). Observation is conducted against plant destruction and yield component. Observation results show that: 1) one larvae causes plant damage at the age of 30,45, and 60 days after planting at a rate between 7.21% - 22,69% and able to decrease the yield from 16.9% to 36.7%, 2) the threshold of the yield decrease for plants with an age of 45 dap (days after planting) is around 2 to 3 larvae per hill, while for the plants age of the 30 dap, 4 larvae per hill will decrease the yield up to 69%, 3) the economical threshold with an assumed control cost of Rp 185,000,- per ha with paddy yield price of Rp 14,000,- per kg is taken for case of larvae at 3rd instar,  while for the plant age of 30 dap has a value of 10.8 larvae per hill.
Key words: rice, armyworm, economic threshold

ABSTRACT. 
Efficacy of Trichoderma sp. and Gliocladium sp. to Control Sheath Blight Disease (Rhizoctonia solani) on Maize. Sheath blight is an important disease in corn. The disease could cause significant yield loss when infection occurs on susceptible varieties. Disease control using the microorganism antagonist is an alternative for disease management. Research was carried out in a laboratory, greenhouse and field from 2010 to 2012. The research objective was to compare several biological agents for controlling sheath blight disease on corn. In vitro laboratory tests identified that out of sixteen isolates of microorganisms, only 3 isolates which had the potency to suppress the pathogen of sheath blight over 50%, namely TT1; TM; and GM. Conidia development among the three isolates of microorganism the highest was by TT1. In the greenhouse, three isolates of microorganisms showed potential of decreasing sheath blight disease up to 70%. The Gliocladium isolates decreases the disease by 53%. Research results from the field indicated the antagonist had decreased sheath blight disease by 67%. Isolates of Trichoderma and Gliocladium fungus could reduce the yield loss by 23% by suppressing the infection of sheath blight disease.

INTRODUCTION

Spodoptera litura nuclear-polyhedrosis virus (SlNPV) (Borrelinavirus litura) is one of the insect pathogens infecting cutworm (Spodoptera litura) on soybean. This virus was first discovered in cutworm larvae in Central Lampung (Arifin and Waskito, 1986). Since 1985, experiments on the use of SlNPV to control cutworm were carried out at the now defunct, Bogor Research Institute for Food Crops.
Numerous experiments reported that SlNPV have high biotic potency (Arifin, 1993). As a biological agent, SlNPV is compatible with the integrated pest management (IPM) concept because: (a) its host-specificity only to the soybean cutworm and some other noctuids species, (b) it does not affect predators and parasitoids, and does not upset non-target host, human body, and environment, (c) it may alleviate insecticide resistant problem, and (d) it is compatible with most other control methods (Maddox, 1975; Starnes et al., 1993). There are several major reasons whySlNPV is suitable for a biological agent to control cutworm: (a) cutworms is a major pest attacking various kinds of vegetable and food crops, (b) considerable amount of broadspectrum, toxic, synthetic insecticides are used against cutworm, and (c) many cutworms are resistant to most major insecticides group. Efforts to develop SlNPV as a biological control agent can be conducted in three steps: (a) production of SlNPV, (b) solve the constraints affecting the effectiveness ofSlNPV, and (c) optimizing application techniques of SlNPV.
The purpose of this paper is to provide information on biological properties, production, and application techniques of SlNPV as a guidance in the control of cutworm on soybean.
