Abstract

Sweet potato production is plagued by pests Cylas formicarius Fabricus. These pests can be controlled by using entomopathogenic fungus as a biological control agent. Local biological agents will have a better adaptation and higher performance to control pests compared with biological agents which are introduced from other areas. This study aims to explore the local isolate entomopathogenic fungal species, identify and testing the pathogenicity on C. formicarius. Implementation of the study consists of several stages: collection and maintenance of insects, exploration entomopathogenic fungus, and the effectiveness test of entomopathogenic fungal isolates in the laboratory. The entomopathogenic fungus types which can be found in South Central Timor is Metarhizium anisopliae and Beauveria bassiana. Both of these fungi cause mortality in larvae of C. formicarius respectively by 80.75% (Metarhizium anisopliae) and 80.25% (Beauveria bassiana). Therefore, both types of the fungus should be developed as a biopesticide for controlling pests C. formicarius.Keyword : Metarhizium anisopliae, Beauveria bassiana, Cylas formicarius Directory for female scat lovers.

Abstract

This study is entitled "Host Plants and Eating Ability of Keong Mas (Pomaceacanaliculata) in some Paddy Varieties in Malaka District". Keong Mas are type of snails which are considered as invasive pests. In Malaka, in 2010-2012 there was a snail boom which caused severe damage to rice to “puso”. This study had been conducted from June 2018 to November 2018. The research aims to study the host plants and the ability to eat of the snails in several rice varieties. The snails were tested for its ability to feed on water plants which were considered as alternative hosts of paddyplants. Host testing was undertaken through forced testing and selective testing of several aquatic plants in rice fields. The eating ability test was carried out on four weeks old paddy varieties cultivated by farmers in Malaka. Fifty rice seedlings were planted in a circle, ten seedlings perplanting hole and were repeated for four times. The number of seeds which were encroached by the juvenile snails was tabulated and analyzed. The result shows that 6 succulent plants were favored by the snails, namely Limnocharis flava, Colocasia esculenta, Ludwigiaadscendens, Monochoriavaginalis, Ipomoea aquatica and Cat tile / Sasoser (Typha spp). The most vulnerable paddy seeds to snails are Ciherang (a), Mapan, Impari 12 (ab), Mokongga (bc), IR 68, Sibogo, and Red Rice (cd), and the most resistant to snails' is Black Rice variety (d).

Abstract

Corn kernels that are stored for a longer period are susceptible to pest infestation by Sithopilus zeamais. To overcome these problems, we need environmentally friendly pest control techniques, namely the use of resistant cultivars. This study aims to determine the level of resilience of 22 local Timor corn cultivars against the Sitophilus zeamais L. Pest. The results showed that the highest total population was found in the Muke Bunga Putih cultivar (121 individuals), Desa Kie Dusun 3 (107, 5 individuals), Silawan Kuning (109.5 individuals), Desa Oenlasi Dusun 4 (141.5 individuals), while the lowest total population were in the Haikesak Putih cultivar (11.5 individuals), Tastim 1 Putih (15 individuals), and Tasifeto Timor Biboki Anleu Putih (17 individuals). Bunga Merah Muke cultivar, Pulut Putih Muke cultivar, and Bunga Putih Fatumonas cultivar have the smallest development period (30 days), while Kie Dusun 1 and Malaka 2 Kuning cultivars have the largest development periods (35 days). There are 7 cultivars, namely Haikesak Putih, Tastim 1 Putih, Bunga Merah Fatumonas, Desa Kie Dusun 1, Malaka 1 Putih, Putih Fatumonas and Tasifeto Timur Biboki Anleu Putih that are resistant to S. zeamais pests. Keywords: cultivar, Timor local maize, Sitophilus zeamais.
