Abstract:
We investigated the predation ability of big-eyed bugs Geocoris ochropterus on different single prey species of thrips, whiteflies, and aphids. Results indicated that G. ochropterus adults consumed the highest number of aphids per day (33.6 ± 3.35). First instar nymphs of G. ochropterus showed low ability to consume prey, while from second to fifth instar nymphs showed high ability to consume prey with significant differences. The number of eggs deposited per female fed on whiteflies was significantly different larger than other prey types. In addition, development time of Geocoris ochropterus nymphs first to fourth instar was longest when fed on aphids and significantly different among prey types. Results suggest that G. ochropterus consumed the highest numbers of aphids, with the order of preference aphids > whiteflies > thrips.

Abstract:
Big-eyed bugs Geocoris spp. are a natural enemy species presented in many parts of the world that have been extensively researched because of the benefits that they bring to plants. In Vietnam, big-eyed bugs are found in many places, especially in farming complexes or large farms. In Ho Chi Minh City, Geocoris sp. was found in Pham Van Coi Commune, Cu Chi District, Ho Chi Minh City, with bug density fluctuations across seasons at an average of 5.33 ± 2.67 individuals per point. The density of the big-eyed bug in Cu Chi District was 03 times higher than the density recorded in Ham Tan District, Binh Thuan Province. Morphological and molecular-based COI genes identified the speciments from Cu Chi, Ho Chi Minh City, and Ham Tan, Binh Thuan are Geocoris ochropterus. From the research results, these two sampling sites will be selected to further evaluate the rate of natural increase of the big-eyed bug Geocoris ochropterus.

Abstract:
Bọ mắt to Geocoris ochropterus là loài ăn mồi đa thực, đã và đang được quan tâm nghiên cứu và áp dụng trong phòng trừ sinh học côn trùng gây hại ở nhiều nước trên thế giới. Trong nghiên cứu này, các thí nghiệm phản ứng chức năng được thực hiện để đánh giá khả năng phòng trừ sinh học rầy mềm của bọ mắt to Geocoris ochropterus thu thập ở Củ Chi. Trong thời gian 24h, có sự khác biệt rất có ý nghĩa về mặt thống kê về tổng số rầy mềm bị bọ xít mắt to tiêu diệt giữa các nghiệm thức. Bọ mắt to tiêu diệt trung bình 12.7 ± 2.51; 21.33 ± 1.52; 31.33 ± 2.08; 40 ± 2; 40 ± 1.15 rầy mềm tương ứng lần lượt với các mật độ 20, 30, 40, 50, 60 con rầy mềm, kết quả nghiên cứu chỉ ra rằng bọ mắt to thể hiện phản ứng chức năng phù hợp với kiểu II (Holling, 1959). Thí nghiệm phản ứng số lượng biểu thị đường cong số rầy mềm bị tiêu diệt gia tăng khi mật độ bọ thành trùng tăng từ 05 con. Kết quả nghiên cứu cho thấy Bọ mắt to Geocoris ochropterus là loài có khả năng áp dụng trong phòng trừ sinh học côn trùng gây hại.
