چکیده

The paddy field ecosystem is a place for interactions between plants and animals, especially rice grasshoppers. Grasshoppers act as eaters of plants, course, become threat to agriculture so that they can reduce agricultural productivity. This study aims determine the diversity Orthoptera: Acrididae in fields Banyuasin Village, Riau Silip District, Bangka Regency habitat conditions Regency. research descriptive quantitative using purposive sampling method insect net handsorting techniques. Measurement environmental factors carried out by taking data on soil temperature, moisture, light intensity. were analyzed Shannon index evenness index. Based observations, there 6 types family found ecosystem, namely 16 individuals Valanga nigricornis, 12 Xenocatantops humilis, 11 Phlaeoba fumosa, 13 Traulia azureipennis, 9 Oxya hyla 3 Trimerotropis pallidipenni. analysis showed grasshoppers was 1.70 which classified moderate criteria 0.41 moderate. locust has been obtained optimal temperatures ranging from 35oC-45oC, with 50% moisture.

 Ekosistem sawah merupakan tempat terjadinya interaksi antara tumbuhan dan hewan khususnya padi Belalang. Belalang bertindak sebagai pemakan tentunya menjadi ancaman bagi pertanian sehingga dapat menurunkan produktivitas pertanian. Penelitian ini bertujuan untuk mengetahui keanekaragaman Orthoptera:Acrididae di ekosistem Desa Kecamatan Kabupaten kondisi Bangka. berupa deskriptif kuantitatif dengan menggunakan metode tehnik handsorting. Pengukuran faktor lingkungan dilakukan mengambil suhu tanah, kelembaban intensitas cahaya. Data hasil penelitian dianalisis indeks Shanon, kemerataan. Berdasarkan pengamatan, didapatkan sebanyak jenis yang terdapat pada sawah, yaitu nigricornis individu, humilis berjumlah fumosa azureipennis individu pallidipennis individu.

Contraction in Glycerinated Myofibrils of an Insect (orthoptera, Acrididae)

The A substance of glycerol-treated myofibrils of the femoral muscles of the locust Gastrimargus musicus (Fabr.), removed by a salt solution of high ionic strength, has the properties of actomyosin. A phase contrast study of these fibrils, contracted by the addition of ATP, has revealed that the A bands of most myofibrils shorten during contraction. Changes in density within the A band lead to ...

Effects of Temperature on Behavior of Trimerotropis Pallidipennis (orthoptera, Acrididae)

We observed activity and behavior of Trimerotropis pallidipennis in the field and constructed time-activity budgets during June–July 2003. Grasshoppers began to walk once site temperatures (shaded air temperature 1 cm above soil surface) reached 18.6uC, foraging began once temperatures reached 24.2–31.7uC, and courtship began once temperatures reached 30.3–36.4uC. Mating and oviposition occurre...
