Considering that soybeans are a food ingredient, it is necessary to control insect pests that are appropriate and environmentally friendly to increase soybean production, for example, through an intercropping pattern using flowering plants that can attract beneficial insects. This study aimed to increase soybean production by increasing the number of natural enemies planted through an intercropping soybean pattern with Titonia (Tithonia diversifolia). This research was conducted from April - August 2020 at Aras Kabu Village Deli Serdang District; the method used was direct observation to the experimental field of soybean – Titonia intercropping made with 5 Mapping spacing treatments. Harvesting insects using sweep net and for production is counted from soybean pods. The results showed that the soybean-Titonia intercropping had an effect on soybean production, the highest number of seeds was in the treatment of 50 cm spacing between plants (T4) of 57.33, and the highest weight of 100 seeds was in the treatment of 50 cm spacing between plants (T4) treatment of 15.22. The insect orders found in the area of Titonia-soybean intercropping plantations are Hemiptera, Coleoptera, Diptera, Hymenoptera, Lepidoptera, where many predatory insects, parasitoids, and pollinators are found. Judging from the content of secondary metabolites of Titonia, namely alkaloids, tannins, and flavonoids, the results of Titonia plants, including flower, stems, and leaves, can be used to extract pesticides in controlling insect pests.

Warehouse pests are nuisance pests that cause a decrease in the quality and quantity of harvested grains. Sitophilus zeamais and Tribolium castaneum are important warehouse pest of corn. Apart from attacking corn grains, this pests also attacks rice, wheat, sorghum, soybeans, grain/rice, and green beans. Temperature is a very influential aspect in the life of all insect species, including warehouse pests. This study aimed to determine the appropriate temperature range for controlling warehouse pests of Sitophilus zeamais and Tribolium castaneum which does not interfere with health and is also safe for consumers. This research was conducted at the Pest Laboratory, Faculty of Agriculture, UMSU. The method used was factorial completely randomized design (CRD), the first factor was the use of temperature and the second factor was duration of heating with three replications. The results showed that the application of a temperature of 100 0C for 120 seconds or 150 0C for 60 seconds could cause the mortality of S. zeamais and T. castaneum pests to reach 100% in corn grains in storage.

Various fruit flies are in Indonesia, but only a few species of fruit flies have been found at the red guava plant in Deli Serdang District. Knowing the species of fruit flies are needed to do the proper control. In addition to morphological identification, it is necessary to carry out molecular characterization to obtain accurate results in characterizing species differences. This study aims to identify the fruit fly based on morphology and molecularly PCR-RAPD for mapping the genetic closeness of the relationship between individual fruit flies. Bactrocera morphologically identified at LIPI, namely B. carambolae, B. papayae, B. caudata, B. albistrigata, B. umbrosa, B. curcubitae, B. tau, and B. kinabalu. For molecular identification PCR-RAPD, shows the dendrogram results from the Neighbor-Joining analysis based on RAPD markers of DNA band characters showing the genetic proximity of eight species divided into three groups of Bactrocera based on their location. The closeness of genetic relationships between individuals was analyzed using Pairwise Distance Calculation which describes the genetic distance between species. The results of Pairwise Distance Calculation ranged from 0.13-0.42. By knowing what species there fruit flies are in red guava plantations in the Deli Serdang district, it can make it easier for farmers to monitor and control fruit flies in red guava plantations.
