Abstract

ABSTRACT  A. dorsata bees is one of the bees only growing forest region in the subtropical and tropical Asia and is not found outside of Asia . A. dorsata living in a colony , consisting of a queen bee, bees worker , and drones  bees measuving morphological characteristics of the bee is very important for bee taxonomist to put some type of bee into a particular caste , in the measurement of morphological characters of  bees worker is always selected as the sample trial because the worker bees every day activities related to the environment where the bees. In connection with that have done research on Morphology Study bees worker Apis dorsata Fabr . ( Hymenoptera : Apidae ) Sijunjung Aggregation in April- May 2013 with the aim to determine the morphology of A. dorsata worker aggregation . This research uses descriptive survey method is by way of direct collection of A. dorsata were found in the location study . than  morphometric measurements in the laboratory . From the results of research on morphological studies of worker bees Apis dorsata Fabr . ( Hymenoptera : Apidae) ) in Sijunjung aggregation is derived morphological characters of different sizes in Cu a real , Rs1 , R4 , NH , Ti , while highly significant in R1 .

Abstract

 Thrips populations sp . in Kampung Batu Solok District of Twin Lakes in pepper can reduce the production of vegetables . One of the vegetables contained in this stone village area is chili . The chili is a community that is relatively important and very popular all over the world , and loved by the community chili has low calories and contains vitamin C which is high for a chili fruit contains 20 calories with no fat at all In this regard it has done research on the population density of Thrips sp . ( Thysanoptera : Thripidae ) in pepper in Kampung Batu Twin Lakes District of Solok which aims to determine the population density of Thrips sp . in pepper This study was conducted in September-November 2013, with a descriptive survey method is by way of direct collection against Thrips sp. the research sites. The area used as a study about 30x 20 m. Sampling was conducted on pepper plants already have flowers and pepper plants that have fruit. Physical environmental factors that will be measured are temperature, humidity , and soil moisture . From the research conducted characteristics Thrips sp. found in pepper in Kampung Batu subdistrict Twin Lakes ie, black slim body shape , and jet black , and the wings are fringed and have segmented bodies . The results were obtained an average population density of Thrips sp. on pepper plants that have gained interest of 3.87 individuals / stem and the fruit of pepper plants that have gained 2.92 individual / stem.

Abstract

ABSTRACT The population of aphids (Aphis gossypii) in Kampung Batu Kembar lake district of Solok decrease the production of vegetables. One of the vegetables that there are in the areas of this Batu village is potatoes. The purpose of this study was to determine the population density of Aphis gossypii on potato in Kampung Batu Kembar Lake District of Solok. This study was conducted in September-November 2013 with a descriptive survey method by direct collection against A. gossypii existing research in the location. Field sampling conducted on potato tubers and grow new potatoes will be  harvested a  month. Physical environmental factors measured are temperature, pH  and  soil  moisture. Widely used  as  a  study area  of about 30  x  20  m.  The characteristics of A. gossypii were found on potato in Kampung Batu subdistrict Kembar Lake are body size from 1.1 to 3 mm , konikel one pair , there are winged and wingless and there are a variety of body colors such as black, green, and yellow. From the research that has been conducted on potato in Kampung Batu Kembar Lake District of Solok was concluded on potato tubers grown induvidu obtained 7.69 / month clumps and the potatoes will be harvested obtained 4.6 induvidu / clump. Population density of A. gossypii were found already passed the threshold of pest control.

Abstract

ABSTRACT Dragonflies (Odonata:  Libellulidae)  have  an  important  role  in  rice  field  ecosystem. Dragonflies can serve as an indicator to monitor the water quality of surrounding environment and predators on crop pests of rice, in addition to the dragonfly also play a  role in  health and agriculture. Crocothemis servilia is commonly found in rice crops. So far there are no data on the density of dragonflies (Odonata) including dragonfly C. servilia in the District of Kuranji Anduring. The purpose of this study was to determine the population density of  C. servilia dragonflies (Odonata: Libellulidae) on Rice Planting in Anduring Kuranji District of Padang in West Sumatra. This study was conducted in January-February 2014, with a descriptive survey method. It is by way of direct collection of the C. servilia existing research in the location. Field sampling done at night on dry rice and wet rice fields when the bright moon and new moon. Physical environmental factors measured are temperature and humidity. The area used as a place of research about + 1 Ha. The characteristics of C. servilia which are found are the average length of the male dragonfly C. servilia abdomen is 30 mm long and 27 mm in females. Body of male colored blood red and the female body colered yellow, have teeth, rear wing wider than the front wing, transparent wings with wing base yellowish, eyes slightly purplish red bull and there is a black line along the abdomen . While the female abdomen is yellowish brown with a bla ck stripe along its abdomen, have compound eyes and a pair of antennae are short and fine size. The average of  population density of C. servilia in the rice fields location of Anduring Kuranji District of Padang in West Sumatra on dry fields individu/m2 is 0.15, and the wet rice fields (aqueous) was0.09 individu/m2 .
