Abstract

Lecanicillium lecanii is one type of entomopathogenic fungus that can infect several insects with very variable mortality rates. control solutions using biological agents of entomopathogenic fungi are able to have a good impact and are environmentally friendly. The writing of this study used both primary and secondary data collection methods carried out by observation and quantitative analysis techniques, in the form of observations, explanations of the data obtained, and carrying out the activities related to the spore density test of the entomopathogenic fungus L. lecanii using a haemocytometer at PTPH Coordinator Office for Bojonegoro Region. The results of the spore density test of the entomopathogenic fungus L. lecanii were 6.05×107, which was carried out using rice solid media and potato liquid media for propagation and calculated using a haemocytometer and observed using a binocular microscope with a magnification of 400×. The results of the density test are classified as good quality and able to be applied to plants by farmers to control a pest or Plant Pest Organisms.

Abstract

The used of refugia plants can be a solution in pest control by providing microhabitats for natural enemies. There are predators and parasitoids as alternative hosts. This study aimed to determine the diversity of insect pests in rice plantations using refugia and without refugia plants in Besur Village, Lamongan. This study used the rice variety Mentik Wangi Susu. The sampling method used 3 kinds of traps: sweep net, pit fall trap, and yellow sticky trap. The results showed that the insect pests found were 5 orders, 11 families, and 14 species with a total of 1272 individuals on refugia land and 1534 individuals on land without refugia. The Shanon-Weiner diversity index (H?) of insect pests on refugia land is H? = 1.93 and on land without refugia H? = 1.86 which is in the medium criteria.

Abstract

Abstract Dengue hemorrhagic fever (DHF) is a disease that is a problem in society. Lamongan Regency has been declared a DHF KLB (Extraordinary Event) with a number of 86 cases in 2015. The village with the highest incidence of DHF in Lamongan Regency is Payaman Village. This study aims to analyze the physical and chemical factors of the water used as a breeding ground for Aedes spp. This research is a descriptive study with a cross sectional approach. Sampling was carried out in 50 houses located in Payaman Village, Solokuro, Lamongan district. The research parameters there are volume of water, temperature, pH, value of water turbidity (NTU), and DO value. The results showed that each type of container has different physical and chemical properties of water. The highest volume of water is in the bathtub type with an average water volume of 152,500 ml. While the least was in the axillary types of Musa paradisiaca (185 ml) and Colocasia esculenta (177 ml). The average water temperature at the breeding site ranges from 25-30oC. The acidity of the water ranges from 6-7. The value of DO levels ranged from 5-8.5 ppm. The value of water turbidity ranges from 4.50-25 NTU with an average of 15.31 NTU.

Abstract

Spodoptera litura F. is a plant pest organism (OPT) on shallot plants that must be prevented so that shallots become productive. One way to prevent it is good and not to damage the environment is the use of tumangsari plants in the form of celery plants. The purpose of the study was to determine the effectiveness of celery (Apium Graveolens L.) as a pest population of Spodoptera Litura F. Repellent Plants in the Cultivation of Shallots (Allium Ascalonicum L.) in Pesanggrahan Village. This research is an experimental study using a randomized block design (RAK) pattern, one way ANOVA test data analysis technique with 5% significance and post hoc follow-up test with the smallest difference analysis. The results showed that celery plants were effective in suppressing Spodoptera litura F. pest attacks. The most effective treatment was 4 PTS treatment which could reduce Spodoptera litura F. population and zinc intensity of Spodoptera litura F., which were 1.66 and 0, respectively. 15%.

Abstract

S. frugiperda is a pest that attacks corn plants by eating young shoots/leaves. Leaves that are attacked by S. frugiperda will have many hoisting holes from the edges to the inside. If the attack of S. frugiperda is not immediately controlled, the losses will be crop failure. This study aims to determine the effectiveness of the use of several concentrations of B. bassiana on the intensity of pest attack and mortality of S. frugiperda larvae on maize. This research was conducted in the green house laboratory of Billfath University using a Completely Randomized Design (CRD) consisting of five treatments and four replications. The concentrations of B. bassiana used included K1= negative control (without application), K2= B. bassiana 5 ml/L, K3= B. bassiana 15 ml/L, K4= B. bassiana 25 ml/L and K5= positive control (Chemical insecticide Tiamethoxam 25%) 0.01 g/L. The results showed that the application of the fungus B. bassiana with a concentration of 25 ml/L was effective in controlling S. frugiperda pests on maize (Zea mays L.) which resulted in an attack intensity of 12.50% and larval mortality of 95%..
