Abstract

ABSTRACT One of the harmful insects in maize is the wanderer Grasshopper (Locusta migratoria L.). Grasshopper wanderer often found the area under maize cultivation . Grasshopper wanderer, both young (nymphs) and old, eating the leaves of corn plants, thereby reducing the surface area of leaves. Adult grasshoppers usually eat the leaf edges , while his nymph takes in between bones , causing leaves holes in the leaves. If this locust attack in a high number of population, the leaves of corn plants that are attacked will be devoured. In connection with the matter, has done research on  grasshopper  population  density  wanderer  on  corn  in  the  Village  Banana  Padang  Pauh subdistrict which aims to determine the wanderer grasshopper population densities on corn plants in Padang Pauh subdistrict Banana Village. This study was conducted in September-October 2013, with the method sweep (sweeping) is a way to swing a grasshopper inseknet existing wanderer on corn which is used as a place of research. Field sampling conducted on maize age of 1 month and2 months after planting by using inseknet and hands. Widely used as a research area of 20x20 m. Sampling was conducted at five points with a size of 3x3 m at each point. Physical environmental factors measured are temperature and humidity. From the research that has been conducted in the village of Padang Pauh subdistrict Bananas can be concluded that the grasshopper population density wanderer in maize of different ages 1 month to 2 months of age. Wanderer grasshopper populations on corn gained as much as 1 month of age 0.7 individuals/m² (0.3 nymphs and 0.4 imago), population density is lower than in maize aged 2 months gained as much as 1.8 individuals/m² (0,7 nymphs and 1.1 imago). Grasshopper population density wanderer found already included in the criteria pests.

Abstract

ABSTRACT Rice is the main food as a source of carbohydrates for most of Indonesian society. Farmers at harvest usually storing rice warehouse. During the storage period of rice will be damaged and shrinkage both in quality and quantity. One cause of the decline in the quality and quantity of stored corps from pest attack is a warehouse. One of the pests that attack warehouse is Sitophilus oryzae L. (Rice beetle). This study aims to determine the effect of the use of several of leaves of plants on the development of Sitophilus oryzae L. in rice (Oryza sativa). This research has been carried out in November to December 2013 Laboratory Biology Education Courses STKIP PGRI West Sumatra. This study used  a  Completely Randomized Design (CRD)  with 5  treatments  and  3  replication. As treatments is A (Control/No leaves), B (Bay leaf), C (Sugar apple leaves), D (Soursop leaf) and E (Red betel leaf). Observed data, that is namely mortality, imago population of Sitophilus oryzae and the percentage of damage caused by the attack of rice Sitophilus oryzae. The data were analyzed by analysis of variance with least significant difference test further (LSD) at the 5% level. The results shomed that the use of some types of plants that bay leaf (Syzygium polyanthum), sugar apple leaves (Annona squamosa), soursop leaf (Annona muricata), red betel leaf (Piper crocatum) significant effect on mortality, Sitophilus oryzae imago population and the percentage of damage caused by the attack of rice Sitophilus oryzae. The leaves are most effective for controlling Sitophilus oryzae attack is red betel leaf (Piper crocatum).

Abstract

Polyploidy in the frog Rana cancrivora can be done by providing a temperature shock. The thing need to consider in treatment temperature shock at  the egg is the beginning of a shock, temperature of shock and duration of shock. The research aims to identify and test the effect of temperature shock 36⁰C to the development of the embryo, and the success of poliploidisation of frog R. Cancrivora. The research was conducted in Biology Laboratory STKIP PGRI West Sumatra. The results shows that administration of 36⁰C temperature shock on egg fertilization influences on the development of frog embryos R. Cancrivora i.e. on the treatment D (45 minutes after fertilization). Yet, the temperature shock is 36⁰C does not show any influence on the success of poliploidisation of frog R. Cancrivora.
