Life History, Damage, and Gall Development of the Gall Midge, \u3ci\u3eNeolasioptera Brevis\u3c/i\u3e (Diptera: Cecidomyiidae), Injurious to Honeylocust in Michigan

Neolasioptera brevis is univoltine in Michigan. Adults issue in late spring, and females deposit eggs in rows on the lower side of young shoots of honeylocust. Larval eclosion occurs shortly after: there are three larval instars. The gall is polythalamous and may have 20 or more larvae. The third-instar larvae overwinter, and pupation occurs in spring. The gall injury kills sorne shoots, but most damage is cosmetic. One can monitor for adult emergence in late April or May by observing cast pupal cases protruding from the gall. Control, if needed, should be directed at adults

Notes on the Life cycle of \u3ci\u3eNemoria Rubrifrontaria\u3c/i\u3e (Lepidoptera: Geometridae)

(excerpt) While surveying for insect pests of sweet fern, Myrica aspleniifolia L., two unidentified eggs were detected on foliage samples collected in June 1972 near Barton City, Alcona County, Michigan. the eggs were transferred to petri dishes with sweet fern foliage for rearing. Subsequently, one of the larvae that emerged was reared to adulthood and identified as Nemoria rubrifrontaria Packard. This note describes the life cycle of this insect

Seasonal Shoot-Feeding by \u3ci\u3eTomicus Piniperda\u3c/i\u3e (Coleoptera: Scolytidae) in Michigan

Seasonal shoot-feeding by Tomicus piniperda (L.) was monitored at 2­ week intervals on 15 Scotch pine, Pinus sylvestris L., trees from 8 April through 16 November 1994 in southern Michigan. All shoots that showed evidence of T. piniperda attack were removed every two weeks. In 1994, initial spring flight of T. piniperda began on 22 March. At least two live T. piniperda adults were found on the 15 trees on each sampling date from 8 April through 1 November 1994. In addition, at least one freshly attacked, beetle- free shoot was found on each sampling date except for 1 November. The greatest numbers of newly attacked shoots, with or without adults present, were found from mid-June through mid-August. All adults found in April and May were likely parent adults, while those from June onward were primarily brood adults. Therefore, at all times of the year, live T. piniperda adults can be found on live pine trees, either feeding in the shoots or overwintering at the base of the trunk. Implications of these findings are provided in light of the US federal quarantine on T. piniperda

An Evaluation of the Health and Physical Education Programs in the High Schools of Utah

During the past ten years there has been an increased evidence of the importance of health and physical education in the United States. Leaders in this field are attempting to establish physical education in its rightful place in the school curriculum

Growth and Recruitment of Two Penaeids in the Bay of St. Louis, Mississippi During 1979

Juvenile brown (Penaeus aztecus, Ives) and white (Penaeus setiferus, Linnaeus) shrimp were collected from two stations of a nursery area in St. Louis Bay Mississippi, during May to October, 1979. Periods of shrimp recruitment and growth were determined to discern whether the concurrent environmental variables of salinity and temperature had an influence on shrimp abundance and yield. Growth estimates were obtained from length frequency measurements of trawl samples taken over a 24-h period per month from each station. An analysis of variance of length versus the variables of sex, month, station, time of day, salinity and temperature was run for each species. Station, month, and month-·sex were found significant (P≤ .05) for both species. Additionally, sex and station-month were found significant (P≤ .05) for P. aztecus. A multiple regression of number of shrimp versus salinity, temperature, and salinity and temperature revealed that shrimp number significantly ( P≤ .05) varies with changes in salinity in P. aztecus. Temperature appeared to have little effect on shrimp abundance and productivity

Leech Parasitism of the Gulf Coast Box Turtle, Terrapene carolina major (Testudines:Emydidae) in Mississippi, USA

Ten leeches were collected from a Gulf Coast box turtle, Terrapene carolina major, found crossing a road in Gulfport, Harrison County, Mississippi, USA. Eight of the leeches were identified as Placobdella multilineata and 2 were identified as Helobdella europaea. This represents the second vouchered report of leeches from a box turtle. Helobdella europaea is reported for the first time associated with a turtle and for the second time from the New World

RENEWABLE ENERGY–POWERED HYDROGEN GENERATION AND STORAGE FROM AMBIENT MOISTURE

This research combines the proven Electrochemical Hydrogen Production and Storage System with a renewable energy source for safe and reliable utilization in Department of Defense and Navy applications. Photovoltaic cells provide the most robust and cost effective renewable energy combined with minimal complexity and weight compared to other available renewable energy sources. Previous research has proven solar panels are capable of consistently achieving the desired energy output levels for hydrogen generation. The critical component of this research is the design and installation of a coupled control system and graphics display to effectively distribute energy from the solar panels to the different components of the generation system while monitoring system status and regulating production autonomously. Once all components function as desired independently, they are combined and assessed to confirm operational viability and a final configuration to maximize practical utilization is investigated. The final product is the fully autonomous coupled system utilizing the implemented controller as well as a capabilities study and a proof of concept report.Ensign, United States NavyApproved for public release.
