Abstract

One component of integrated pest control is biological control or biological control based on the bioecology of the pest by taking into account the results obtained and their long-term effects through ecology and economy. The success of controlling a type of pest requires studies on various factors that affect the life of a pest, namely biology, morphology, ecology, genetics, and evolution. Knowledge of the biology of a pest species will provide appropriate information in breaking the life cycle or making the surrounding environment not provide optimal carrying capacity so that the pest population can be suppressed below the economic threshold. Spodoptera exigua is a polyphagous insect pest that eats from many plant types. In the larval stage, this pest attacks more than 20 species of cultivated and wild plants. For over twenty years, the onion caterpillar S. exigua has been the main target for chemical control but is still the main pest on onion crops. Spodoptera exigua attacks occur throughout the year in North Sulawesi and are spread over a wide geographical range, allowing genetic differences within the species. Gene mutations cause the occurrence of genetic diversity in a species in a population. High genetic diversity in individuals in a population can be one inhibiting factor in successfully controlling a pest species. Increasing knowledge about the biology of a pest species is very important to understand its habits, reproductive ability, and distribution which will later be used to limit and control the pest population.

Abstract

This research aims to determine habitat conditions as an ecological indicator and measure the level of diversity of insects of the order Hymenoptera on rice plantations in the Manembo-nembo sub-district. The method used in this research is quantitative descriptive. Insect samples were collected using the sweeping net and yellow pan trap methods. The Shannon-Wiener diversity index formula, Pielou's similarity index (E), and Simpson dominance index (C) are used to measure the level of diversity. The results of research on rice plantations found insects of the Hymenoptera order as many as 35 genera, 16 subfamilies and 14 families with a total of 470 individuals with normal habitat conditions where Hymenoptera insects can still carry out activities on rice plantations. Wasp insects from 24 genera also have functions as biological control agents, most of which are parasitoid and predatory wasps, which have potential as ecological indicators in rice plantations in the Manembo-nembo sub-district. The level of diversity is included in the medium criteria, as is the evenness index value. In contrast, the dominance index is included in the low criteria even though the Pimplinae family dominates rice cultivation in the Manembo-nembo sub-district.

Abstract

This research was motivated by the chicken dung flower plant (Tagetes erecta L.) which is one of the plants that is often found in several areas in North Sulawesi, containing active chemical compounds such as alkaloids, terpenoids, saponins, tannins and flavonoids which can improve health. improve health. improve health. improve health. improve health. improve health. used as a vegetable protector. This study aims to determine the effectiveness of chicken manure flower extract on the mortality and antifeedant effect of chili aphids Myzus persicae sulz. This examination utilized an exploratory technique utilizing the leaf separate strategy utilizing a Totally Randomized Plan (CRD) design comprising of 4 treatments and 4 replications. Each treatment was given chicken manure flower extract with respective concentrations, namely P0 (0%), P1 (5%), P2 (10%), and P3 (15%). The results showed that the administration of chicken manure flower extract had a significant effect on the death of the chili aphid Myzus persicae sulz. The higher the extract from chicken manure flowers the higher the death rate of chili aphids Myzus persicae sulz and chicken manure flowers have an antifeedant effect at a concentration of 15%. So it can be concluded that giving chicken manure flower extract is effective in increasing the mortality of Myzus persicae sulz at a concentration of 15%, namely an average of 4.75 birds and has an antifeedant effect at a concentration of 15.%, namely an average of 0.350 grams.

Abstract

Forensic entomology is the science of insects which is used to analyze cases related to forensics, namely death. This is based on the close relationship between humans and insects who live side by side. Insects can be a factor in determining the Postmortem Interval (PMI) so that it is useful in the forensic investigation process. Medicolegal insects are insects that are used as evidence in death cases. This research aims to obtain the diversity of insect species, the morphological characteristics of insects, the characteristics of insects in experimental pigs that died from hanging, poisoning and stabbing and based on the stage of decomposition. The results of this research examine temperature, soil pH, air humidity and the decomposition process of local pigs. The results of research on the decomposition stage in 3 deaths (hanging, stabbing, and poisoning) showed differences in the time of death, where the hanging carcass decomposed more quickly than the stabbed and poisoned carcass. In the decomposition stage, the first insect encountered is the order (Diptera) where these insects damage internal organs such as the brain and liver and also damage body cells. The temperature results of local pig carcasses placed outdoors ranged from 32.2-34.50C, while indoor carcass temperatures ranged from 26.77-33.43 0C. The degree of acidity (pH) of carcasses placed outdoors ranges from 5.13-8.53 while indoor carcasses ranges from 6.0-7.77. The environmental temperature of animal bodies placed outdoors ranges from 26.35-39,740C, while humidity ranges from 57.79-86.10%. The temperature of animal bodies in the room ranges from 27.54-31,520C, while humidity ranges from 71.50-85.37%.

Abstract

The hydroponic system is modern agricultural cultivation with various planting media as a substitute for soil, so hydroponics is an agricultural activity that is carried out by using water as a medium for distributing nutrients. This research aims to determine the effect of alternative nutrition to substitute AB mix on the growth and yield of hydroponic lettuce (Lactuca sativa L.). The research method was an experiment in a completely randomized design(CRD), using 5treatments with 4 repetitions, namely P0 (control/with ABmix nutrition) of 700-800 ppm, P1 (800-900 alternative nutrients), P2 (900-1000 ppm alternative nutrients), P3 (1000-1100 alternative nutrients), P4 (1000-1200 alternative nutrients), were analyzed by one way ANOVA analysis with a significance level of 0.05. Parameters observed were plant height, number of leaves, root length, leaf width, and fresh weight. The results showed that providing alternative nutrition significantly affected plant height, leaf width, and fresh weight of lettuce (Lactuca sativa L.). With the best treatment of 900-1000 ppm with plant height 35-41 cm, number of leaves 15-17, leaf width 17-18 cm, and plant wet weight 120-209 grams, the lowest yield was in treatment P0 with plant height 30-33 cm. the number of leaves is 15-16, and the wet weight of the plant is 117-146 grams
