Cultivation of chili plants is often affected by pests, generally insect pests that attack the leaves, stems and fruit of chilies. The use of bioinsecticides derived from entomopathogenic fungi can control insect pests and suppress the development of insect pests, but will not cause death to natural enemies. Entomopathogenic fungi commonly used are Metarhizium anisoplia (Hypocreales: Clavipitaceae) and Beauveria bassiana (Hypocreales: Cordycipitaceace). The impact of using bioinsecticides on insects does not reduce the abundance and diversity of insects, especially natural enemies. Research results. The use of bioinsecticides on chilies has been tested in the laboratory, the research has a real effect so that it is tested in the field, therefore the research was carried out. Therefore, this study aims to observe the effect of four bioinsecticides on phytophage attack and to observe the effect of four bioinsecticides on arthropod communities. The research was conducted using a randomized block design (RBD). In this experiment, it was carried out with 4 replications and 5 treatments (BKbTp, BSwTd4, MSwTp1, MSwTp3, Control). Each experimental plot consisted of 8 clumps of plants. With a total of 160 plants for the entire experiment. To observe the intensity of the attack was carried out with 5 sample points of observation. Meanwhile, for the arthropod observation on the canopy, a census was carried out on each chili plant. The results showed that the intensity of attacks on the eaters of leaves, pistils and raw fruit did not show any significant difference. Meanwhile, the intensity of the attack of leaf and ripe fruit suckers showed a significant difference in one observation.caused many attacks on chili plants, Aphis gosypii especially on the pistil, so that the pistil on chili plants was reduced. It can be seen that the number of individual herbivores in chili plants is the highest compared to other insect species. The number of individual herbivorous species found in chili cultivation in all treatments was the highest compared to other arthropod species, ranging from 66-87%. The most herbivorous species found in chili plants were not treated with bioinsecticides. In chili plants treated with bioinsecticide, the higher the number of predator species, the lower the number of herbivorous species. The highest number of arthropod species was found in chilli cultivation which was applied with BSwTd4 isolate from the fungus species Beauveria bassiana. Species of arthropod herbivores found chili namely: Spodopteralitura, Henosepilachna elaterii, Empoasca sp., Nezara viridula, Leptocorisaacuta, Junoniaalmana, Aphisgossypii, Psydococcusmaritimuss, Thripstabaci, Bemisiatabaci, Tetranychusurticae, Valanga sp., Larinus sp. , Coreus marginatus, Atractomorpha crenulata, Cyclosia papilionaris. Species of arthropod predators found dilahan chili namely: Tibellustenellus, oxyopesmacilentus, Phidippus sp., Theridiidae, Salticidaecosmophasis, Heliophamus sp., Thiania sp, ArgiopeCatenulata, Coccinella transversalis Fabricius, Menochilussexmaculatus, Micraspisdiscolor, Harmonia sp., Coelophora sp., Coccinella transversalis, Mantis religiosa Nymph, Theopropus elegans, Mantis religiosa, Condylostylus sp., Coccinelidae nymph, and Metioce sp. The parasitoid arthropod species found in chili fields were: Sarcophaga carnaria, Apanteles sp., and Psyttalia fijiensi. Neutral arthropod species: Dolichoderus thoracicus, Musca autumnalis, Trigona sp., Monomorium pharaonis, and Aedes sp. The conclusion from this research is The lowest attacks on leaf suckers were found in MSwTp3 treatment, leaf-eating in BSwTd4 treatment, pistil suckers and fruit flies on raw and ripe fruit treated with BKbTp. The highest species diversity of predatory arthropods and herbivorous arthropods was treated with BSwTd4, while parasitoid insects and neutral insects were treated with MSwTp1.
