Egg Parasitoid Complex of Helicoverpha armigera (Hübner) and Conopomorpha cramrella Snellen in North Sulawesi
نویسندگان
چکیده
Backround: Helicoverpa armigera is major maize pest, while Conopomorpha cramerella cocoa main insect pest. Their larvaes lie in corn cob and pulp which can be controlled using egg parasitoids. Methods: Exploring H. eggs on female flowers a plant along the 50 m line at 10 points with 4 distance to obtain C. cramrella. Egg parasitoids were obtained by taking from cacao pod, Corcyra cephalonica traps straight 3 distance. Result: include Trichogramma sp. Trichogrammatoidea armigera. Corn grown between coconut palms has higher parasitism than without palm shade highest was Bolaang (60.91±2.52 %). Parasitoids of Trichogaramma produce unrearable offsprings eggs. Dominant found only two parasitized pod. Tombariri. trap latest method for monitoring sp parasitoid The low.

Malaria in North Sulawesi, Indonesia
The incidence and impact of malaria in North Sulawesi have declined both in the short term during the 1990s, and over a much longer timespan (though perhaps less continuously) since the end of the colonial period. The improvement already seems to have been well underway before deliberate vector control activities became extensive in the second half of the 1970s, and environmental changes affect...
متن کاملEvolution and manipulation of parasitoid egg load.
In proovigenic parasitoids such as Leptopilina boulardi, the female emerges with a limited egg load and no further eggs are produced during its adult life. A female thus runs the risk of exhausting this limited supply of eggs before the end of her life. Given that the production of an egg is costly, what is the evolutionarily stable egg load at emergence? This question has attracted a lot of at...
متن کاملOverexpression of poplar wounding-inducible genes in Arabidopsis caused improved resistance against Helicoverpa armigera (Hübner) larvae
Four highly inducible genes of poplar trees, PtdKTI5, PtdWIN4, PtdPOP3 from hybrid poplar (Populus trichocarpa × P. deltoides) and PtKTI2 from trembling aspen (Populus tremuloides Michx.) have been individually transformed into Arabidopsis thaliana for overexpression. High transcriptional level of each transgene in transgenic Arabidopsis lines was confirmed by RT-PCR analysis. The development, ...
متن کاملCantharidin Impedes Activity of Glutathione S-Transferase in the Midgut of Helicoverpa armigera Hübner
Previous investigations have implicated glutathione S-transferases (GSTs) as one of the major reasons for insecticide resistance. Therefore, effectiveness of new candidate compounds depends on their ability to inhibit GSTs to prevent metabolic detoxification by insects. Cantharidin, a terpenoid compound of insect origin, has been developed as a bio-pesticide in China, and proves highly toxic to...
متن کاملCharacterization of a Cry1Ac toxin-binding alkaline phosphatase in the midgut from Helicoverpa armigera (Hübner) larvae.
Midgut membrane-bound alkaline phosphatases (mALP) tethered to the brush border membrane surface by a glycosylphosphatidylinositol (GPI) anchor have been proposed as crucial for Cry1Ac intoxication. In the present work, two full-length cDNAs-encoding alkaline phosphatases in the midgut of Helicoverpa armigera larvae were cloned and named HaALP1 (GenBank accession no. EU729322) and HaALP2 (GenBa...
