A number of miscellaneous agricultural problems were also investigated.The following report makes brief mention of each of the more important projects and summarizes the more important results secured during the biennium. COÖPERATION WITH OTHER AGENCIES The station has been fortunate in having coöperative relationships with a number of related agencies.The extensive and cordial coöp- eration that has existed in the past with the United States Depart- ment of Agriculture has been continued and the work somewhat expanded. The coöperative work with the United States Department of Agriculture has included investigations in small grain production and breeding, corn breeding, and the control of cereal diseases with the Office of Cereal Crops and Diseases; investigations in dry-land agriculture with the Office of Dry-land Agriculture; investigations with alfalfa diseases with the Office of Forage Crops and Vegetable Diseases; and experiments with alfalfa, the sorghums, turf grass, and other forage crops with the Office of Forage Crop Investigations of the Bureau of Plant Industry; a survey of five counties with the Division of Land Classification and Survey of the Bureau of Chem- istry and Soils; a study of factors influencing the palatability and quality of meat and other live-stock problems with the Division of Animal Husbandry of the Bureau of Animal Industry; investiga- tions in the propagation and distribution of forest trees with the Forest Service; and investigations in farm organization, cost of pro- duction, land utilization, wheat marketing, and hay grading in coöp- eration with the Bureau of Agricultural Economics. Coöperative relations have been continued with the Kansas State Board of Agriculture in connection with the regulatory activities of the board. The station has provided facilities for analytical deter- minations of feeding-stuffs, live-stock remedies, and dairy products and has maintained in coöperation with the board a state seed- testing laboratory.Coöperative research in a limited way has also been undertaken on industrial projects with two commercial agencies. 1. Contribution No. 39 from the director’s office. (5) 6 AGRICULTURAL EXPERIMENT STATION THE PURNELL ACT The Purnell act, approved by President Coolidge February 24, 1925, authorized a federal appropriation for the support of the Agricultural Experiment Station of $20,000 for the fiscal year ending June 30, 1926, with increases of $10,000 annually until the fiscal year ending June 30, 1930, when a maximum annual appropriation of $60,000 would be made.The grants of money authorized by the Purnell act were “made subject to legislative assent of the several states and territories to the purpose of said grants.” The Kansas legislature, complying with this provision, passed in its forty-second regular session, February, 1927, house concurrent resolution No. 13 as follows: RELATING to the acceptance by the State of Kansas of the provisions of an act of congress approved February 24, 1925, for the more complete endow- ment of agricultural experiment stations. “Be it resolved by the house of representatives of the state of Kansas, the senate concurring therein: That the provisions of the act of congress entitled ‘An act to authorize the more complete endowment of agricultural experiment stations, and for other purposes,’ approved February 24, 1925, be and the same is hereby accepted by the state of Kansas, and the federal appropriations are hereby placed under the control of the State Board of Regents, subject to the rules and regulations expressed or implied in the act of congress above named.” The Purnell act particularly authorizes investigations in the fields of agricultural economics, rural life, and home economics, as well as support for investigational work “bearing directly upon the produc- tion, manufacture, preparation, use, distribution, and marketing of agricultural products.” For the fiscal year ending June 30, 1928, the Kansas Agricultural Experiment Station received as a result of the Purnell act a grant of $40,000. The money was expended as follows: 35 per cent for investigational work in agricultural economics, including marketing, 20 per cent for investigational work in home economics, and 45 per cent for the support of all other kinds of investigational work of the station. THE SOIL SURVEY The state soil survey resumed in 1925 has been continued during the past biennium. The survey is being made in coöperation with the Bureau of Chemistry and Soils of the United States Depart- ment of Agriculture. Prior to this biennium, a reconnaissance soil survey had been made of the western half of the state and a detailed survey of 11 counties and some smaller areas in the eastern part of the state.During the past biennium detailed surveys of Clay, La- bette, Wilson, and Doniphan counties have been completed and are now in progress in Johnson and Crawford counties.There remain 42 counties in eastern Kansas yet to be surveyed. (Fig. 1.). It is planned to push these fundamental investigations of the soil re- sources of Kansas as rapidly as the support of the work will permit. D IRECTOR ’S R EPORT, 1926-1928 7 LAND, BUILDINGS, AND EQUIPMENT One tract of land embracing 1.6 acres was purchased during the biennium from Mr. Wm. M. Aye. This tract was secured to com- plete the area purchased during the preceding biennium to provide a larger area for plant breeding for the Department of Agronomy. New buildings constructed during the biennium include a sheep barn for the Department of Animal Husbandry, a laying house for the Department of Poultry Husbandry, a new residence for the superintendent of the Fort Hays Branch Experiment Station, and other smaller buildings for the branch stations mentioned later in this report. FIG. 1.—Map of Kansas showing progress of state soil survey. The new sheep barn is used primarily for housing the flock of sheep maintained for investigational and instructional purposes. The barn consists of a two-story central portion 32 feet wide and 52 feet long, with one-story wings 32 feet wide and 90 feet long on each side. The first floor of the central portion is divided into bins, a combination lambing and shearing room, a sleeping room for the shepherd, and a central driveway. The upper story is used for hay and a central driveway.

Janzena,1 and Winnie Hallwachsa Edited by David L. Wagner, University of Connecticut, and accepted by Editorial Board Member May R. Berenbaum November 11, 2020 (received for review April 6, 2020) We have been field observers of tropical insects on four continents and, since 1978, intense observers of caterpillars, their parasites, and their associates in the 1,260 km2 of dry, cloud, and rain forests of Area´ de Conservaci ´onGuanacaste (ACG) in northwestern Costa Rica. ACG’s natural ecosystem restoration began with its national park designation in 1971. As human biomonitors, or “insectometers,” we see that ACG’s insect species richness and density have gradually declined since the late 1970s, and more intensely since about 2005. The overarching perturbation is climate change. It has caused increasing ambient tempera- tures for all ecosystems; more erratic seasonal cues; reduced, erratic, and asynchronous rainfall; heated air masses sliding up the volcanoes and burning off the cloud forest; and dwindling biodiversity in all ACG terrestrial ecosystems. What then is the next step as climate change descends on ACG’s many small-scale successes in sustainable biodevelopment? Be kind to the survivors by stimulating and facilitating their owner societies to value them as legitimate members of a green sustainable nation.

C. postal 19.020, 81531-990, Curitiba, PR, e-mail: [email protected] Neotropical Entomology 32(3):481-485 (2003) Biologia Reprodutiva e Longevidade de Euplectrus ronnai (Brèthes) (Hymenoptera: Eulophidae) RESUMO - O ectoparasitóide Euplectrus ronnai (Brèthes) é um dos componentes do complexo de espécies que parasitam a lagarta do trigo Mythimna (Pseudaletia) sequax Franclemont (Lepidoptera: Noctuidae). Não há dados na literatura sobre o potencial de parasitismo, preferência por ínstares do hospedeiro e longevidade desse parasitóide, o que motivou a realização do presente trabalho. O parasitismo ocorreu entre o terceiro e o quinto ínstares do hospedeiro; lagartas de segundo instar inviabilizaram o desenvolvimento do parasitóide, e no primeiro e no sexto ínstares não houve oviposição pelas fêmeas de E. ronnai. O número de ovos depositados pelas fêmeas aumentou com o estádio de desenvolvimento do hospedeiro, variando de 1,5 ovos/lagarta no terceiro instar a 3,6 ovos/lagarta no quinto ínstar. A proporção de lagartas parasitadas entre os diferentes ínstares mostrou que E. ronnai apresenta preferência pelo quarto e quinto ínstares de M. sequax. Não houve diferença no tempo de desenvolvimento, na razão sexual, no número médio de lagartas parasitadas e na porcentagem de lagartas parasitadas em testes de livre escolha entre lagartas de quarto e de quinto ínstares. Entretanto, o número de parasitóides/hospedeiro foi significativamente maior em lagartas de quinto ínstar. A fecundidade média das fêmeas de E. ronnai foi de 63,7 ovos e cada fêmea parasitou a média de 20,3 lagartas.

  • Non-Target Effects of Insect Biocontrol Agents and Trends in Host Specificity Since 1985
    CAB Reviews 2016 11, No. 044 Non-target effects of insect biocontrol agents and trends in host specificity since 1985 Roy Van Driesche*1 and Mark Hoddle2 Address: 1 Department of Environmental Conservation, University of Massachusetts, Amherst, MA 01003-9285, USA. 2 Department of Entomology, University of California, Riverside, CA 92521, USA. *Correspondence: Roy Van Driesche, Email: [email protected] Received: 6 October 2016 Accepted: 7 November 2016 doi: 10.1079/PAVSNNR201611044 The electronic version of this article is the definitive one. It is located here: http://www.cabi.org/cabreviews © CAB International 2016 (Online ISSN 1749-8848) Abstract Non-target impacts of parasitoids and predaceous arthropods used for classical biological control of invasive insects include five types of impact: (1) direct attacks on native insects; (2) negative foodweb effects, such as competition for prey, apparent competition, or displacement of native species; (3) positive foodweb effects that benefited non-target species; (4) hybridization of native species with introduced natural enemies; and (5) attacks on introduced weed biocontrol agents. Examples are presented and the commonness of effects discussed. For the most recent three decades (1985–2015), analysis of literature on the host range information for 158 species of parasitoids introduced in this period showed a shift in the third decade (2005–2015) towards a preponderance of agents with an index of genus-level (60%) or species-level (8%) specificity (with only 12% being assigned a family-level or above index of specificity) compared with the first and second decades, when 50 and 40% of introductions had family level or above categorizations of specificity and only 21–27 (1985–1994 and 1995–2004, respectively) with genus or 1–11% (1985–1994 and 1995–2004, respectively) with species-level specificity.

Most of eulophines are ectoparasitoids that attack concealed hosts in protected situations, such as leafminers, woodborers and leaf rollers. The subfamily are frequently involved in biological control programs directed against dipteran and lepidopteran leaf-mining pests, and many eulophine genera have been considered economically important. The taxonomy and distribution of the species in Asia, especially in Java, are however still poorly studied despite the fact that the subfamily is an important group for sustainable agriculture. This study is based on the specimens newly collected from many localities in Java and Bali using sweep netting, Malaise trapping, yellow-pan trapping and rearing from their hosts. All the three tribes (Elasmini, Cirrospilini and Eulophini) of the subfamily Eulophinae are recognized in the islands. A single genus of Elamini, three genera of Cirrospilini and 19 genera of Eulophini are recognized in the islands and they included 14 genera as new records for the islands and 66 undescribed species. A total of 110 species are recognized in Java and Bali; of those about 86% are new records for the islands and about 60% are undescribed species.

    forest health news No. 169, January 2007 ISSN 1175-9755 URABA LUGENS BIOLOGICAL CONTROL PROGRESSING NICELY Uraba lugens (gum leaf skeltoniser) (Nolidae) is an Australian moth that was first found in New Zealand in 1992 at Mount Maunganui. After several years it was eradicated from there but in 2001 it was found in Auckland. It is not known whether the Auckland population originated from the Mount Maunganui ones or represents a separate incursion from Australia. It has now spread throughout the greater Auckland region, with additional records in Waikato, Northland, and Bay of Plenty — (see http://gis.scionresearch.com/maful/viewer.htm for a map of the distribution). Modelling work carried out at Ensis predicts that Uraba has the potential to survive in all the commercial eucalypt growing regions of New Zealand and is thus a threat to the expanding eucalypt industry as well as to amenity trees. Uraba lugens has been recorded from nearly 50 species of Lisa Berndt working with Cotesia urabae in the quarantine facility Eucalyptus in New Zealand and, as the common name implies, these are the main hosts. However, it has been recorded from other In 2004 Ensis gained approval to import four parasitoids of Uraba species as well. These include Agonis, Angophora, Lophostemon, lugens into containment (FH News 143 August 2004), and work Metrosideros, and Tristaniopsis. These are not so surprising began to determine if any of these would be suitable biological because they all in the family Myrtaceae as is Eucalyptus. What control agents. (FH News 150 April 2005). Since then many is somewhat surprising are records from Betula, Fagus, Fraxinus, problems have been encountered with mating and rearing the Liquidambar, Populus, and Quercus.

    J. Biol. Control, 23(3): 221–228, 2009 Impact of integrated pest management modules on the activity of natural enemies in castor ecosystem H. BASAPPA Directorate of Oilseeds Research, Rajendranagar, Hyderabad 500030, Andhra Pradesh, India. E–mail: [email protected] ABSTRACT: Investigations were carried out during 2001–2004 to study the impact of biointensive integrated pest management (BIPM), chemical pesticide intensive integrated pest management (CIPM) modules and non–integrated pest management (non–IPM) modules (farmers’ practice) on the natural enemies of insect pests of castor in Andhra Pradesh. BIPM module proved to be relatively safer to natural enemies with 16.13 and 66.10 % average field parasitization of Achaea janata (L.) eggs and larvae by Trichogramma chilonis Ishii and Microplitis maculipennis Szepligeti, compared to 6.92 and 21.2, 8.80 and 24.00, 8.92 and 22.35 % in CIPM module and non–IPM modules 1 and 2, respectively. M. maculipennis cocoon number per plant increased with increase in duration after treatment in the BIPM module whereas it decreased in CIPM and non–IPM modules. Similarly, average parasitisation by Charops obtusus Morley (3.54%), Rhogas spp. (4.60%), Apanteles hyposidrae Wilkinson (13.85%), Euplectrus maternus Bhatnagar (7.92%) on A. janata larvae and Cotesia flavipes Cameron (8.96%) on Spodoptera litura (F.) was higher in the BIPM module compared to CIPM module (1.65, 1.59, 3.50, 2.37 and 2.49%) and non–IPM modules 1(1.16, 0.80, 2.70, 1.20 and 2.68%) and 2 (1.50, 1.19, 2.80, 3.82 and 1.99%), respectively.
