Nursaidah, Iin (2013) Komposisi Serangga Kanopi Pohon Apel di Desa Poncokusumo Kabupaten Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk mengetahui kelimpahan, struktur komunitas, diversitas serangga kanopi yang mengunjungi pohon apel di Poncokusumo pada musim bunga dan buah, mendiskripsikan komposisi serangga kanopi pohon apel pada kedua musim, dan mengetahui pengaruh musim dan warna perangkap bejana kuning dengan biru terhadap kelimpahan serangga kanopi pengunjung pohon apel, serta mengetahui struktur komunitas vegetasi dibawah pohon apel pada musim bunga dan buah. Pencuplikan serangga kanopi dilakukan dengan metode perangkap bejana. Masing-masing pencuplikan dilakukan empat kali setiap musim. Analisis vegetasi dibawah pohon apel menggunakan metode Kurva Spesies Area. Data perbandingan kelimpahan, diversitas, struktur komunitas baik serangga maupun vegetasi semak dibawah pohon pada musim bunga dan buah dianalisis dengan indeks nilai penting dan diversitas (Indeks Shannon-Wiener). Pengaruh musim dan warna perangkap dianalisis dengan uji-t tidak berpasangan. Kesamaan komposisi dua musim dan warna perangkap dianalisis menggunakan Indeks kesamaan Bray-Curtis. Hasil menunjukkan Serangga kanopi pohon apel Poncokusumo pada musim bunga lebih banyak dibandingkan musim buah dengan nilai berturut-turut 1014 dan 480 spesimen. Struktur komunitas dengan pola dominan ditunjukkan dengan indeks nilai penting yang diperoleh famili Aphididae pada musim bunga dengan INP 56,87% dan Famili Cecidomyiidae pada musim buah dengan INP 55,26% . Diversitas serangga kanopi di musim bunga dan musim buah berturut-turut dengan nilai 2,37 dan 2,40. Kesamaan komposisi serangga kanopi dengan indeks Bray-Curtis pada musim bunga dan buah sebesar 0,13. Berdasarkan hasil uji-t tidak terdapat perbedaan kelimpahan serangga kanopi secara signifikan antara perangkap warna biru dengan kuning. Struktur vegetasi naungan pohon apel pada musim buah didominasi oleh Capsicum annum dengan INP 37,65%
English Abstract
This study aims to determine the abundance, community structure, diversity of insects visitor to the apple tree canopy in Poncokusumo in flowering and fruiting phase (season), to describe the composition of the canopy insect, and determine the influence of season and trap color (yellow and blue) to the abundance of insect visitors, as well as to know the structure of vegetation of ground cover shrubs in Poncokusumo. Sampling was conducted using colour water pan trap. Each sampling conducted four times each season. Analysis of ground cover shrubs vegetation under the apple tree was used Species Area Curve method. Comparison of data abundance, diversity, community structure both insects and ground cover shrubs in the flowering and fruiting phase were analyzed with significance test and diversity index (Shannon-Wiener index). Effect of season and color was analyzed by unpaired t-test. The similarity of the composition of canopy insect in two seasons was analyzed based on color using Bray-Curtis similarity index. Results showed that the abundance of canopy insect in the flowering phase was greather than that in the fruiting phase in a row with a value of 1014 specimens and 480 specimens. Community structure with the dominant pattern indicated by the index values indicated that important family in the flowering phase was Aphididae (56.87%) while that in fruiting phase was dominated by Cecidomyiidae (55.26%). The diversity of canopy insects in both season was almost equal. Similarities between the two compositions canopy insects with Bray-Curtis index in the flowering and fruiting phases was met at 0.13. Based on the results of t-test there was no significantl difference in the abundance of canopy insects collected in blue and yellow traps. The vegetation structure of ground cover shrubs was dominated by Capsicum annuum (37.65%).
