Abstract

ABSTRACT The research aimed to identify important pests which attack sweet potato in the field. Field and laboratory research were conducted. The field research was carried out in sweet potato cropping areas in Minahasa Regency, North Minahasa regency and  Tomohon. The laboratory research was conducted in plant pests and disease laboratory, Faculty of Agriculture Sam Ratulangi University Manado to idedntify the important pest species which were found on sweet potato plants. The duration of the study was four months starting from December 2010 until March 2011. Survey method was applied with purposive random sampling.  The research was used 4 period of plant growth namely 1 month, 2 months,3 months, and 4-5 months after planting. The result showed that there were five orders identified, attacking sweet potato since the age of 1-4 months in Minahasa regency, Tomohon and North Minahasa regency. The five orders were Orthoptera, Hemiptera, Homoptera, Lepidoptera, and Coleoptera. The damage on the leaves were caused by pests coreidae, Cicadelidae, Spodoptera sp (Noctuidae), Valanga sp (Acrididae), and Oxya sp. (Acrididae), whereas on the stem was Omphisa sp (Pyralidae). Damage on the tuber was caused by Gryllotalpa sp (Gryllotalpidae), Cylas formicarius (Curculionidae) and Oryctes sp (Dynastidae). Key words : Important Pest Plant Sweet Potatoes, Ipomea batatas L.

Abstract

ABSTRACT   Research was aiming to determine the effectiveness of the attractant methyl eugenol + traps modification in the catch of species of fruit flies in the chilli plants at any given time and to identify the types of fruit flies trapped with methyl eugenol + traps modification on chilli crop acreage. The field research was conducted in the area of chilli crop in three places namely District Pineleng, Tompaso / Langowan and Modoinding. Observation number and type of fruit flies was performed at intervals of 2 weeks of observation for 3 months. The result showed that the number of fruit fly caught or trapped dead at 30 traps set in chilli crop acreage was 1278. The highest trapped was 164 whereas the lowest trapped was 89. The number of male fruit flies trapped was high implying that reduction of male fruit fly population in the field. There were five types of fruit flies identified from area of Pineleng, Tompaso and Modoinding namely Bactrocera umbrosa Fabricus, Bactrocera dorsalis (Hendel), Bactrocera philippinensis, Bactrocera carambolae, and Bactrocera sp. The five types were attracted to methyl eugenol. Key words : MAT (male annihilation technique), Bactrocera umbrosa Fabricus, B. dorsalis (Hendel), B. philippinensis, B. carambolae

Abstract

ABSTRACT Fruit flies is one of the important pests which attack fruits in Indonesia and very detrimental economicaly. The objective of this research was to determine mating behaviour of fruit flies Bactrocera sp., testing their response to attractants methyl eugenol and cue lure as well as identification  some species of fruit flies that attack belimbing, ketapang and paria fruits. The fruits samples which were affected by fruit flies were collected  from plantation at Lopana and Kapitu, South Minahasa. Imago was assessed  at laboratory of entomology,  Faculty of Agriculture. Result showed that mating time of these species was occured between 17.10 – 18.45. Sexual maturity of belimbing fruit flies was  10 -12 days. Whereas ketapang fruit flies and paria fruit flies were 10 – 14 days and 11 – 13 days respectively.  B. dorsalis complex was  attracted to methyl eugenol. While B. albistrigata and B. cucurbitaceae Coq.were attracted to cue lure. Keywords : fruit flies  Bactrocera sp. Belimbing, ketapang, paria fruits, methyl eugenol and cue lure
