Berry sucker insect pest, Dasynus piperis china (coreidae; Hemiptera) is one of the major insect pest on pepper. D. piperis to attack fruit of pepper with suck of fruit liquid and the final effect is empty to fruit and damaged. To find out of the level of damage and destruction caused by D. piperis have been done at 6 districts of Bangka Island namely Mendo Barat, Sungai Selan, Sungai Liat, Belinyu, Koba and Toboali since January to December 2002. For each district were observed 5 farmers field of estate crops. Every farmer field were observed tens plant of pepper in connection with fluctuation population and level of fruit damage. The observation have been done on the flower season of pepper, after flower season and after harvest. The result showed that fluctuation population and infested level of D. piperis at each observation almost the same, while among district were variated. The highest infestation was found in Sungai Selan, followed by Belinyu, and Mendo Barat namely 36.82;32.03 and 29.48 % respectively. The infestation level on Sungai Liat, Toboali and Koba were low namely 14;79.58 and 20.98 % respectively. The level of damage in Mendo Barat was highest than an other location namely 8.66; 8.07; 6.67; 5.71;4.89 and 3.09 % in Mendo Barat, Sungai Selan, Belinyu, Koba, Toboali and Sungai Liat respectively.

<p><strong>Pestalotiopsis desseminata on cashew: its biology and interaction with Helopeltis antonii</strong></p><p>Pestalotiopsis desseminata is one of pathogens causing leaf spots. die-back of shoots and inflorescence of cashew plant. It is assumed there is an interaction between the attack of Helopeltis antonii and the fungus in Ihe ield so that the damage becomes more devastating. The objectives of (his research were to investigate several aspects of fungal biology (pathogenicity, mycelial growth, acervuli production, sensitivity to fungicides) and its interaction with //. antonii. The esearch was carried out from April 1999 to March 2000 at the laboratory and green house of Pest and Disease Department Research Institute for Spice and Medicinal Crops, Bogor. /' desseminata was diectly isolated from cashew leaves. Pathogenicity test of P. desseminata isolate was conducted on cashew seedlings. The fungal growth and fungicide effects were carried out in vitro on agar medium. The interaction between P. desseminata and H. antonii was examined by inoculating the fungus and insect, either individually or in combination, on cashew seedlings. The results showed that P. desseminata isolate fomis black spherical acervuli containing oblongs conidia with 5 cells, and the outermost cell has 3 flagellate. Acervuli could only be produced on the cultue illuminated continuously by 600 lux translucent lamp. Pathogenicity test of several isolates of /' desseminata on cashew seedlings caused spherical leaf spot symptom, individually or coalesced as bigger leaf spots. In vitro fungal mycelia growth could be suppressed by several fungicides, including bcnomyl 50% (I ppm) and Uiiopanate-mcthyl 70% (10 ppm) Combining inoculation between P. desseminata and //. antonii resulted in moe severe (devastating) die-back compared with individually inoculated.</p>
