Species composition, abundance pattern of Bemisia tabaci and its co-inhibitant on eggplants under different chemical fertilization condition

This study assesses the interaction, relationship and recorded several species of insectacarines pest on the underside of eggplant leaves. Variation of infestation levels by a community of insect-acarines detected on the leaves namely Whitefly Bemisia tabaci, aphids Myzus persicae, thrips Thrips palmi, mite and spider mite Tetranychus cinnabarinus caused serious damage at the initial stage of plant growth with flowering and fruiting stage. Different effects by fertilizer levels were observed affected the presence of insect-acarines and dominancy of major pest. The result also showed that all the insectspest was colonized competitively on the leaves for every sampling date due to treatments effect. Whitefly was found to be the most dominant on eggplants which resulted in more than 50% from other insect pest composition, particularly at higher fertilizer levels. Some occasions described that the predator-prey relationship has been identified as a major role in the habitat competition. There was an obvious trend of competitor pest of whitefly such as aphids’ population was found higher than whitefly in all treatments. Generally, this study suggests that the dominant species and the first invader probably could suppress or mediate the other competitor significantly once they occupied on the same quality of host plants.

Solar Decathlon Latin America and Caribbean: Comfort and the Balance between Passive and Active Design

This article contains an overall analysis of the results obtained by the four highest scoring teams in the Solar Decathlon Latin America and Caribbean 2015 collegiate sustainable habitat competition. Considering that the prototypes developed were based on energy self-sufficiency when operational, it was considered necessary to propose this analysis based on the degree of suitability of each of these models based on their different performances from the perspective of comfort conditions. It was observed that the design of the prototypes did not manage to properly adjust the relationship between passive and active conditioning elements based on the location’s conditions. Accordingly, this article concludes that a balance of the two aforementioned conditioning modes recorded better results based on the measurements taken.

Life in the Slow Lane: Ecology and Conservation of Long-Lived Marine Animals

<em>Abstract.</em> —The history of the Hawaiian monk seal is one of remarkable evolutionary persistence but recent and severe decline. The species may have persisted in the Hawaiian Archipelago for the past 15 million years. Its initial contact with humans probably occurred when Polynesians first settled the Archipelago, perhaps 2,000 years ago. Shortly thereafter, the monk seal was likely extirpated in the main Hawaiian Islands and reduced to its current configuration of six main reproductive colonies. The first written record of the species is from 1805, when it was discovered on Lisianski Island. Through the remainder of the 1800s, it was exploited for skins and oil and for food by shipwrecked sailors. By the turn of the century, at least two of the six reproductive colonies had been extirpated and the species was severely depleted. In this century, the Hawaiian monk seal has suffered more from habitat competition and loss than from direct exploitation. Habitat loss has occurred in the form of permanent human settlement with associated disturbance, deposition of marine debris, physical and biological alteration of its terrestrial environment, and biological alteration of its marine environment. Thus, human activities have played a major role in determining the status and trends of the species over the past two centuries. The historical record also suggests that human access to the Northwestern Hawaiian Islands is increasing, and such activities may become a greater impediment to recovery if they are not limited to those compatible with wildlife conservation. Unfortunately, we are often unable to predict the compatibility of proposed activities. In the face of such uncertainty, is further development of the Northwestern Hawaiian Islands worth the risk of extinction of the Hawaiian monk seal?
