Rhynchochoris humeralis (Thunberg), commonly known as the "shoulder bug" or "long kiss bug," is a pest belonging to the order Hemiptera, family Polygonaceae. It is also referred to by several other names such as "horns" and "shoulders." This species is widely distributed across various provinces in China, including Jiangsu, Zhejiang, Hubei, Jiangxi, Hunan, Fujian, Taiwan, Guangdong, Guangxi, Guizhou, Sichuan, and others. The primary host plants of this insect include rice, millet, sorghum, corn, sugarcane, tea, citrus fruits, apples, pears, and sand fruit. The damage caused by this pest is quite severe. Nymphs feed on the sap of rice plants, particularly affecting seedlings. Early infestations can cause the seedlings to appear scorched, leading to plant death. During the heading stage, the damage may result in empty panicles or white ears, significantly reducing crop yield. Adults of Rhynchochoris humeralis measure approximately 22 mm in length and are typically green with a long shield-like body. Their antennae are filamentous and consist of five segments. The front edge of the pronotum is distinctly angled on both sides, and the "shoulder" area features a black border with multiple black markings. The scutellum is elongated and has a large tongue-like projection. The eggs are light green and spherical. Nymphs go through five instars: the first to third instars are pale yellow to reddish yellow with dark spots, while the fourth instar has a green thorax and yellow abdomen with prominent wing buds. The fifth instar is entirely green. In terms of its life habits, this species completes one generation per year in southern regions. Adults overwinter in dense branches of fruit trees, leaf clusters, and hidden spaces in buildings. In April of the following year, they begin laying eggs, with peak egg-laying occurring between May and October, especially in July. Eggs are laid in groups of about 14, arranged in orderly rows. August marks the peak period for nymph development. The first instar does not feed immediately after hatching, but the second and third instars start feeding and often occur in small groups of 3–5. The fourth and fifth instars are more active feeders. By November, most nymphs have developed into adults, and they begin their overwintering process by mid-December. Natural enemies of this pest include orange spines, flat-bellied wasps, yellow ants, crickets, and spiders. To manage this pest effectively, several control methods are recommended: 1. Eliminate adults and nymphs promptly. 2. Remove egg masses and newly hatched nymphs. 3. Apply chemical treatments during the critical period, which is before wintering begins and after nymphs hatch until the third instar. Recommended sprays include 50% dichlorvos EC diluted 800–1000 times, 50% parathion EC diluted 1500–2000 times, 2.5% emulsifiable concentrate diluted 3000 times, 20% suspension concentrate diluted 360 times, and 50% malathion EC diluted 1000–1500 times. 4. Encourage and protect natural predators to maintain ecological balance. By combining these strategies, farmers can effectively reduce the impact of Rhynchochoris humeralis on their crops.

Food Safty And Quality Service

what is Food safety and Quality services?

Food safety and Quality services is a broad field that covers a variety of professional activities and solutions to ensure the safety and quality of food from production, processing, storage, transportation to marketing. Here are some of the main services:

2. Risk assessment and management: Identify and assess possible food safety risks in the food production chain, and develop and implement a risk management plan to reduce these risks.
3. Laboratory testing and analysis: Provide chemical, microbiological, physical and sensory testing and analysis services for food samples to ensure food quality and safety.
4. Supply chain monitoring and traceability: Through advanced technology and systems, real-time monitoring and traceability of the food supply chain to ensure traceability and transparency of the product source.
5. Education, training and capacity building: Provide food enterprises and related personnel with food safety and quality management training and education to improve their knowledge and skills.
6. Technical support and research and development: Provide technical support and research and development services for specific food or production process, including new product development, production process improvement and food safety technology research and development.
7. Crisis management and emergency response: In the event of a food safety incident, provide crisis management strategies and emergency response measures to protect public health and the reputation of the business.
8. Audit and third party audit: Conduct internal and external food safety and quality audits to verify that the enterprise complies with the specified standards and requirements.
The goal of Food Safety and Quality services is to protect the health of consumers, maintain public trust in the food industry, and help companies improve product quality, meet regulatory requirements and enhance market competitiveness. These services are usually provided by professional consulting companies, inspection agencies, scientific research institutions or relevant government departments.
