Abundant Population

<p>Rice cultivation in tidal swampland of South Kalimantan has been practiced by farmers in the long period and influences the population of rice stem borer. This paper describes rice cultivation in tidal swampland of South Kalimantan and its impact on injury level caused by rice stem borer. Land preparation by slashing and spinning the rest of rice crop and then left it to rot, can thwart rice stem borer larvae to become imago (adult). Seeding by transplanting several times can kill stem borer larvae, while cutting the leaves of rice seedlings before planting can reduce egg population of the pest. Rice husk ash application is also able to reduce plant damage caused by stem borer. Another factor that contributes to the decreasing level of plant damage due to the pest is the presence of “purun tikus” (Eleocharis dulcis) weeds. Rice stem borers are more interested in laying eggs in the weed than that in rice plant resulted in low damage of rice planted adjacent to “purun tikus” area. Abundant population of natural enemy in “purun tikus” area also effectively suppresses the development of rice stem borer.</p><p>Keywords: Rice, cultivation, rice stem borer, tidal swampland</p><p align="center"><strong><br /></strong></p><p align="center"><strong>ABSTRAK</strong></p><p>Budi daya padi di lahan pasang surut Kalimantan Selatan sudah sejak lama dilakukan petani dan berpengaruh terhadap penurunan populasi dan tingkat serangan hama penggerek batang padi. Makalah ini menguraikan budi daya padi di lahan rawa pasang surut Kalimantan Selatan dan pengaruhnya terhadap tingkat kerusakan tanaman akibat penggerek batang padi. Penyiapan lahan dengan menebas sisa tanaman padi dan memintalnya kemudian membiarkannya membusuk dapat menggagalkan larva penggerek batang padi menjadi imago (dewasa). Pembibitan dengan cara tanam pindah yang dilakukan beberapa kali juga dapat mematikan larva penggerek batang padi. Sementara pemotongan daun bibit padi sebelum ditanam dapat mengurangi populasi kelompok telur hama tersebut. Pemberian abu sekam juga dapat menurunkan kerusakan tanaman akibat serangan hama tersebut. Faktor lain yang berkontribusi terhadap pengurangan tingkat kerusakan tanaman padi adalah keberadaan gulma purun tikus. Penggerek batang padi lebih tertarik meletakkan telurnya pada gulma tersebut dibandingkan pada padi sehingga kerusakan padi yang ditanam berdekatan dengan area purun tikus lebih rendah. Populasi musuh alami yang melimpah pada area purun tikus efektif menekan perkembangan hama penggerek batang padi.</p><p>Kata kunci: Padi, budi daya, penggerek batang padi, lahan rawa pasang surut<br /><br /></p>

Effects Of Radiation

Germ cells from the rice stem borer Chilo suppresalis, were examined by light and electron microscopy. Damages to organelles within the germ cells were observed. The mitochondria, which provide the cell with metabolic energy, were seen to disintegrate within the germ cell. Lysosomes within the germ cell were also seen to disintegrate. The subsequent release of hydrolytic enzymesmay be responsible for the destruction of organelles within the germ cell. Insect spermatozoa were seen to lose the ability to move because of radiation treatment. Damage to the centrioles, one of which is in contact with the tail, may be involved in causing sperm immobility.

AbstractA gelatine-based diet for rearing the onion maggot, Hylemya antiqua (Meigen), that contains sucrose, evaporated milk, yeast hydrolysate, wheat embryo, cellulose powder, n-propyl disulfide, water, and antibiotics is described. Three consecutive generations reared on this medium were equal in puparial weights, percentages of pupation, adult emergence, and egg hatch, to those reared on onion bulbs. The procedure is simple and two man-hours per week is sufficient for producing 1000 maggots daily.
