POTENTIAL ROLE OF WILD CRUCIFERS IN THE PRESERVATION OF DIADEGMA EUCEROPHAGA HORSTMAN (HYMENOPTERA: ICHNEUMONIDAE), A PARASITOID OF THE DIAMONDBACK MOTH, PLUTELLA XYLOSTELLA LINNAEUS (LEPIDOPTERA: PLUTELLIDAE)
Get PDFLaboratory and field experiments were conducted to evaluate the potential role of two species of wild crucifers in the preservation of Diadegma eucerophaga Horstman, a parasitoid of the diamondback moth, Plutella xylostella Linnaeus. In the laboratory, D. eucerophaga developed quite well on P. xylostella larvae fed on leaves of two species of wild cruciferous plants, Nasturtium heterophyllum BL. and Cardamine hirsuta L. These wild crucifers may serve as food and oviposition sites for P. xylostella. In the field, N. heterophyllum and C. hirsuta planted adjacent to insecticide-treated cabbage plots provided refuge for D. eucerophaga parasitoids

This research is aimed to determine whether classes taught using Tiktok have better results than classes taught without using Tiktok. Students today are familiar with Tiktok because of its easy and flexible access. By using Tiktok students can create their writings so that they are more interesting to read and can be seen by many people. This is a quasi-experimental research. The experimental group was taught using Tiktok and the control group was taught without using Tiktok. The author used a pre-test to find out that both groups had relatively the same background knowledge in the research variables and a post-test to find an increase in scores as a measure of achievement. The author uses tests to calculate and hypothesize.

No full textMacrotermes gilvus Hagen is primary pest of castor (Jatropha curcas L.), as the termites can damage roots and stems. The purposes of this research were: (1) to estimate population size of colony in field stations at KIJP Pakuwon, (2) to study M. gilvus foraging range, (3) to study the symptomatology and lethal time of M. brunneum as biocontrol agent to M. gilvus in the laboratory, (4) to study the effectiveness of the M. brunneum Petch as biological control agents against M. gilvus in KIJP Pakuwon. The study was conducted from November 2009 to October 2010 in the insect pathology laboratory and insect taxonomy laboratory Departement of Plant Protection, Bogor Agricultural University (IPB), Zoology Laboratory LIPI Cibinong and in the KIJP Pakuwon. Laboratory test was designed using Completely Randomized Design (CRD) and the data were subject to probit analysis. Triple mark recapture methods were used to estimate termite population in the field. In the laboratorium the effective density of conidia as biotermiticide was 1,21x106 konidia/mL, and this led to mortality of M. gilvus up to 85,45%, while the density of 1,08x106conidia/mL resulting in mortality of 78,63%. The suspension of fungi at density 1,21x106conidia/mL was poured at each experimental station (150 mL/station). The result showed that in block I (15.210 m2), block II (5.700 m2), block III (27.000 m2), 8, 1 and 15 termite colonies have been detected respectively from which, 150.388, 59.219, and 149.459 individus were found. In block I, the termites maximum foraging range as far as 140,5 m, as compared to 140 m in block III. In all blocks, we noted the significant decrease of termite population after application of M. brunneum, from initial population 359.066 individus to 15.015 individusRayap Macrotermes gilvus Hagen merupakan salah satuhama penting tanaman jarak pagar yang merusak sistem perakaran pada pangkal batang tanaman, dan mengakibatkan tanaman terluka, patah dan akhirnya mati.

Get PDFThe development of learning media is a series of processes or activities carried out to produce learning media based on existing development theories. The media in question is learning media so the development theory used is the theory of learning development. In addition to media, in a teaching and learning process, teachers are also required to use RPP which is a reference for the activity plan that will be carried out during the learning process. Assessment tools are also needed to see the extent to which students have achieved their goals. Thus, the development of learning media is also equipped with RPP and learning outcome tests as requirements in a learning process. Teachers at Siswo Utomo Kindergarten, Kepuhdoko Village, experienced many obstacles/barriers in implementing appropriate and interesting learning. Which of course can make it easier to provide understanding to students at the institution. Thus, learning becomes more active and leads to student-centered learning (SCL). Development of an android-based learning application intended for Siswo Utomo Kindergarten, Kepuhdoko Village, Tembelang District, Jombang Regency. This educational institution was chosen because in TK (Kindergarten) Siswo Utomo is the place where the author teaches and devotes himself to Kepuhdoko Village. The facilities and infrastructure in this institution have not been used optimally to support learning media. Based on the results of observations in the field, namely TK (Kindergarten) Siswo Utomo Kepuhdoko Village, Tembelang District, Jombang Regency, it shows that the condition of the facilities and infrastructure is still far from expectations. Several things found in the field include: (1) the existing learning media facilities are still very minimal in use, (2) teacher skills in designing learning using learning methods are still ineffective
