Özet:

This study was carried out to determine the effects of methanol extractes obtained from grapefruit (Urtica dioica), grapefruit (Ocimum basilicum), grapefruit (Humulus lupuıus) and grapefruit (Euphorbia cyparissias) in contact with and preventing the leaving of eggs against adult Callosobruchus maculatus (F.) (Col.: Chrysomelidae). Furthermore, the contact effects of plant extracts with deltametrin mixture in Callosobruchus maculatus adolescents have also been detected. The tests were carried out in laboratory conditions at a temperature of 28±0.5°C in a moisture and dark environment of 55±5%. The contact effect studies were carried out using eight different concentrations of extract (%0.156, 0.312, 0.625, 1.25, 2.5, 5, 10, 20 w/w). Ergine contact effect is determined by the topical application method. At the end of 24, 48 and 72 hours, with increased concentrations of extract, death rates increased. The highest mortality rate was found in U. dioica, while the lowest was found in H. lupulus. In the detection of the preventative effect of putting eggs, 1 ml of extract (2.5%, 5, 10 (w/w) concentrations) is sprayed on the nuts using the spray tower. In terms of the preventive effect of putting eggs, plants are classified as bite>sherbetti tree> breathing>milk. Plant extract mixed with deltametrin has not been found to cause an increase in the toxic effect of deltametrin.
