Abstract

ABSTRACT   The study aimed to: (1) know the type of pests and predator that lived during the growth and production of strawberry plants, (2) know the populations of pests associated to the strawberry plants during vegetative and generative development stages until harvest time. The methodology used was Descriptive Method. Sampling the pests associated to strawberry plants was taken by the Method of Deliberate (Purposive Sampling Method). In the vegetative stage, the plants were in 2-10 weeks after planting, and the generative stage of flowering plants until harvest time, or age 11-20 weeks after planting. The results showed that, the pests on strawberry plants growth and development in both vegetative and generative stages, i.e.: seven order were included in nine families, those were: order Orthoptera with Acrididae and Grylotalpidae families; order Coleoptera with Curculionidae and Chrysomelidae families; order Lepidoptera with Pyralidae families; order Diptera with Drosophilidae families; order Homoptera with Aphididea families; order Acari with Tetranychidae families, and order Mollusca. There were six types of pests which destroyed the leaves on  the vegetative phase, i.e.: Acida turita, Locusta sp., Valanga nigricornis, Chrysocus auratus, Tetranychus sp. and Aphis sp., and a kind of destructive root, that was Gryllotalpha sp. There were 11 types of pests in the generative phase, consisted of: a) six pest species destroyed the leaf, i.e.: Acida turita, Locusta sp., Valanga nigricornis, Chrysocus auratus, Tetranychus sp., and Aphis sp.; b) two kinds of fruit pests, those were : Drosphila sp. and Filicaulis bleekeri, c) as well as a type of root pest was Gryllotalpha sp. Keywords : population type and plant pests and predators; strawberry plants

Abstract

abstract This study aims to understand the interaction of varieties and watering the papaya mealybug in Bangkok and local plants. Research using Completaly Randomized design (CRD) with treatments that Papaya of varieties Bangkok, Lokal, and Watering. Parameters measured were population nymph, imago, and the attack rate of the mealybug P. marginatus on the part of the plant consists of a trunk, the upper leaves, leaves the middle, and bottom leaves. The results showed that the population of nymphs on papaya local watering every day at the upper leaves of the plant has the highest population as much as 71.85 individuals per leaf and the lowest found in papaya Bangkok on watering every three days on the underside of leaves of plants of 1.85 individuals per leaf. Imago population at the local papaya with a watering every day at the middle leaf has the highest population of 27.85 individuals per leaf and the lowest found in papaya Bangkok with a watering every three days at the bottom of the leaf has a population of 1.71 individuals per leaf. The percentage of mealybug attacks were highest in local varieties of papaya with every day watering time (90.89%), followed by papaya local time watering every two days (70.35%), papaya Bangkok time watering every day (67.92%), local papaya time watering every three days (57.32%), papaya Bangkok time watering every two days (42.72%), and papaya Bangkok time watering every 3 days (40.04%).

Abstract

The objectives of thiswork was to study the difference on the population growths of these two pests of tomatoon plots with and without pesticide sprayings for 5 strains of tomatoes obtained from AVRDC (G1-G6) and 4 varieties (G7-G10) available in the local market. The population of leafminer started growing a week after replanting and reached the peak 7-8 weeks then it started declining until 12 weeks after replanting.Statistical analysis showed that there was no significant difference on the population growth of L. sativae on sprayed plots for all strains from AVRDCand varieties G7-G9 but it was significant different from G10. There was also no significant difference on population growths of L. sativae for strains G1,G2 and G4 to G7 and G8 but it was significant different with strains G5,G9 and G10 on sprayed plots and plots without spraying.The population of N. tenuis grew quicker and reached the peak on week 6 after replanting and starts declining until week 12th. Statistical analysis showed that there was no significant difference on the population of N. tenuis on all strains and varieties G7 and G8 on plots without spraying but there was significant difference for all strains and varieties G7-G9 with variety G10. ABSTRAKTujuan penelitian ini untuk mengetahui perbedaan pertumbuhan populasihama penggorok daun, Liriomyza sativae dan kepik tomat mirid, Nesidiocoris tenuis pada petak tanpa penyemprotan pestisida dan dengan penyemprotan pestisida pada 5 galur tomat yang berasal dari AVRDC dan 4 varietas tomat yang tersedia di pasaran.Populasi penggorok daun, L. sativae mulai terlihat sejak seminggu sesudah dipindahkan dan mencapai puncak 7-8 minggu kemudian populasihama mulai menurun sampai 12 minggu sesudah tanaman dipindahkan. Hasil analisis statistika tidak terdapat perbedaan nyata terhadap populasi L. sativae pada petak yang disemprot pestisida untuk semua galur dari AVRDC serta varietas G7- G9 tapi berbeda nyata dengan varietas G10. Juga, tidak terdapat perbedaan yang nyata antara populasi L. sativae untuk galur G1,G2, G4,G7dan G8 tetapi berbeda nyata dengan galur G5, G9 dan G10 pada petak yang tidak disemprot pestisida. Populasi L. sativae terendah pada varietas G10 baik pada petak penyemprotan maupunpetak tanpa penyemprotan pestisida.Populasi N. tenuis berkembang lebih cepat dan mencapai puncak pada minggu ke enam dan ke tujuh serta menurun sampai minggu ke 12 sesudah tanaman tomat dipindahkan.Hasil analisis statistika menunjukkan tidak terdapat perbedaan yang nyata terhadap populasi N. tenuis untuk semua galur dari AVRDC serta varietas G7 dan G8 pada petak tanpa penyemprotan tetapi terdapat perbedaan yang nyata antara semua galur dan varietas G7-G9 dengan varietas G10.

Abstract

ABSTRACT Cocoa is one of the agricultural products that have a big role, especially in terms of employment, regional development, increasing farmer welfare and increasing revenues/foreign exchange. One of the main pests is the cruncher of cocoa C. cramerella Snell. The research aims to get the technology of environmentally friendly cacao borer pest control through the use of sex pheromone traps. The study was conducted in Makarti Jaya Village, Pohuwato District, Gorontalo Province for 3 months (January - March 2017), using Randomized Block Design (RAK), with 3 treatments and 6 replications. The result of the research is the use of the six traps of pheromone sex succeeded in decreasing the intensity of PBK pest attack, after one month of attack intensity attack trapping decreased to 2.23%, lower than pesticide application which only 4.49%.Keywords: pheromone sex Conopomorpha cramerella Snell, cacao fruit snipper
