Abstract

Beetle activity deep inside wood was studied in field (Mt. Yoshida, Kyoto) and laboratory conditions by monitoring the type and amount of frass ejected from beetle galleries of Platypus quercivorus. Twenty-one galleries were selected from five infested Quercus serrata trees for field studies. In the laboratory, frass production was monitored for three galleries using a computer-aided electrical balance (A&D Co. Ltd.). Long-term patterns of frass production from field observation revealed that there are three distinguishable stages; a fibrous frass stage, an intermediate stage, and a powdery frass stage. The duration of the fibrous frass production was clearly different between galleries, ranging from five to twenty one days. The intermediate stage was also different from gallery to gallery, ranging from two to twenty days. Accordingly, the starting time of the third stage, powdery frass production, ranged from the 19th to the 27th day. Under laboratory conditions, the long-term patterns of frass production revealed that in galleries of logs no. 1 and 2 the fibrous frass period was stopped on the 23rd and 22nd day, respectively. Field monitoring revealed there was a negative relationship between the length of fibrous frass stage and the length of the intermediate stage.   Keywords:  fibrous frass stage,  intermediate stage, Platypus quercivorus, powdery frass stage

Abstract

This research focuses on investigating West Kalimantan’s traditional landscapes, shifting cultivation pattern, and comparing the forest dependency of several ethnic groups.  After conducting remote sensing and geographical information system techniques based on the satellite images LANDSAT-TM in West Kalimantan from 1996 to 2006, the decrease of primary dry tropical forest from 36.4% to 15.9% and a little increase of agriculture land from 44.8% to 45.1% were detected. West Kalimantan’s traditional landscape is a combination of primary forest, shifting dry rice-field, rubber plantation, fruits garden and home garden, meanwhile new landscape managed by migrants mainly consist of permanent wet land rice-field, dry land rice, and crop fields. The decreasing forest area forces the native people to shorten the shifting cultivation cycle or to turn to permanent agriculture with the low yield. This situation is the result in the more primary forest clearing for agriculture usage by native people and migrants. It is clear that the traditional landscape of West Kalimantan is particularly dependent upon its most vital element, the forest. Yet, traditional landscape representing the regeneration cycle of forest in West Kalimantan was constrained by changes in managed and modern landscape.

Abstract

The inheritance pattern of resistant tomato to root-knot nematode was studied. GM2 accession and Gondol Putih (GP) cultivars were used as resistant and susceptible parent, respectively. Parental plants, F1 generation, and the F2 generation were grown individually in the sterile soil. One thousand of larvae stage 2 (L2) nematode of M. incognita was infested in each plant. Data of root gall intensity, the number of egg mass, population of L2 nematodes in root and soil were analyzed with the Kormogorov-Smirnov’s test, Chi-square test, and potence ratio. The F2 selected resistant plants then were grown and self fertilized to identify of homozygote plants (F2) related to nematode resistant and good fruit characters. The result showed that the resistant to root-knot nematode was controlled by a dominant gene. Positive correlation between damage levels of roots, eggs mass number and L2 larvae population in the root was significant. Eleven selected plants, conferred the homozygous resistant gene, was prospective lines to be used pedigree or single seed descent selection in producing variety with resistant to nematode, high yield and quality of fruit.   Keywords: tomato, root-knot nematode, resistant gene, dominant, homozygous, correlation

Abstract

The biology of Trissolcus latisulcus Crawford was studied on eggs of  Chrysocoris javanus Westw (Hemiptera: Scutelleridae) which  is a serious pest of Jatropha curcas L.. The aim of this study was to  investigate the biology of Trissolcus latisulcus  as  a basic knowledge for developing a more suitable biological control programme in controlling the  pest C. javanus. The current laboratory study was designed to evaluate developmental duration from egg to adult of C. javanus under room condition temperature: 28.18 + 0.59°C and RH 56.33 + 4.27%. The results showed that the life cycle of immature T.latisulcus consisted of egg, larva ( three instars) , prepupa, pupa. The longevity period of each stadium was one day, four days, one day, and five days respectively. The development time from egg to adult took 12.66 + 1.22 days for female and 11.91 ± 0.73 days for males.The life time from egg to dead adult was 17.40 + 7.38 days for female and 23.70 ± 9.49 days for males. The egg of T.latisulcus was stalked type, the first instar larva was teleaform type and the third instar larva was hymenopteriform type.   Keywords: Jatropha curcas L, Chrysocoris javanus Westw, Trissolcus latisulcus Crawford ,parasitoid eggs
