Problems solved by technology

Moreover, chlorpyrifos and TCP (3,5,6-trichloro-2-pyridinol) may have a synergistic effect
Studies on chlorpyrifos insecticide and cytochrome P450 monooxygenase induction have mostly focused on fish, humans and mice (Wheelock and Eder, 2005; Cui et al., 2008; Lee, 2009), in insects, but on cells There are few studies on pigment P450 monooxygenase

Embodiment 1

[0021] There are many control methods for RIFA, among which chemical control technology is the most effective, deepest and most widely used control method. Spreading bait is the most effective and long-lasting way to control RIFA in a large area, and mound drench is also one of the effective ways to control RIFA in a timely, effective and rapid manner. This application selects 7 different types of insecticides to test the contact toxicity of RIFA to clarify the toxicity difference of different pesticides to RIFA and the sensitivity difference of different grades of RIFA (queen and worker ants) to pesticides.

[0024] The tested RIFAs were collected from Zengcheng, Guangzhou, Guangdong Province and the campus of South China Agricultural University. Referring to the method of Kuriachan et al. (2000), the RIFA colony was collected from the field in a large plastic bucket and placed for 1-2 days. After the ant colo...

Embodiment 2

[0082] Cytochrome P450 (Cytochrome P450, P450 for short) is the core part of the multifunctional oxidase system, which plays a role in terminal oxidation in the oxidative metabolism of the entire enzyme system (Qiu Lihong et al., 1999; Isin and Guengerich, 2007). P450 can participate in the metabolism of various exogenous substances and endogenous substances in insects. The following methods are commonly used for the determination of cytochrome P450 activity: 1. O-deethylation method: the cytochrome P450 enzyme is characterized by the activity of 7-ethoxycoumarin O-deacetylase (ECOD) system activity. After deethylation of 7-ethoxycoumarin (7-ethoxycoumarin) into 7-hydroxycoumarin (7-hydroxycoumarin), the fluorescence value can change (excitation wavelength 368nm, emission wavelength 456nm), using fluorescence spectroscopy Photometer, the change of fluorescence value produced by measuring the amount of 7-hydroxycoumarin is used to characterize the activity of cytochrome P450 (...

Abstract

The invention discloses solenopsis invicta contact insecticide and application of fipronil in eliminating solenopsis invicta. Effective ingredients of the solenopsis invicta contact insecticide are fipronil, phoxim and / or chlorpyrifos. The invention also aims at providing application of the fipronil in eliminating the solenopsis invicta. The application comprises the steps that an ant killing bait containing fipronil is taken and eaten by worker ants of the solenopsis invicta, after the bait is brought in a nest by the solenopsis invicta, medicament is transferred to worker ants, young ants and a queen ant in the nest through frequent activities and trophallaxis feeding behaviors of the worker ants to cause poisoning death of the solenopsis invicta in the whole nest. The solenopsis invicta contact insecticide disclosed by the invention is simple to prepare and convenient to use and has a good eliminating effect.

Description

technical field [0001] The invention relates to an insecticide, in particular to a contact insecticide for red fire ants and the application of fipronil in killing red fire ants. Background technique [0002] The red fire ant (S.invicta) is the most invasive social insect, and has been listed as one of the most invasive and destructive alien pests in the world. RIFA has complex feeding habits, ferocious habits, rapid reproduction and strong competitiveness, which can cause significant economic losses, social hazards and environmental impacts. The omnivorous and aggressive nature of RIFA makes it not only an economic pest, but also a threat to public health. Chemical control measures are still effective measures to control RIFA, but they still cannot eradicate RIFA. Moreover, the long-term use of chemical agents to control RIFA will lead to unexpected rebound. [0003] Fipronil (trade name: Fipronil) is commonly known in English as fipronil. It is a new broad-spectrum insec...
