TL;DR: The tropical Field Station of the New York Zoological Society, at Simla, Arhna Valley, Trinidad, British West Indies, was founded in 1950 and is intended for research in tropical ecology and in animal behavior.
Abstract: [This paper is one of a series emanating from the tropical Field Station of the New York Zoological Society, at Simla, Arhna Valley, Trinidad, British West Indies. This station was founded in 1950 by the Zoological Society's Department of Tropical Research, under the direction of Dr. William Beebe. It comprises 200 acres in the middle of the Northern Range, which includes large stretches of undisturbed government forest reserves. The laboratory of the station is intended for research in tropical ecology and in animal behavior. The altitude of the research area is 500 to 1,800 feet, with an annual rainfall of more than 100 inches. For further ecological details of meteorology and biotic zones see \"Introduction to the Ecology of the Arima Valley, Trinidad, B.W.I.,\" William Beebe.

TL;DR: The host recognition behavior of Compsilura concinnata (Meigen) (Diptera: Tachinidae) was investigated by exposing hosts of various types to female parasitoids and observing them, suggesting that the parasitoid must physically contact a host before examinations and attacks occur.
Abstract: The host recognition behavior of Compsilura concinnata (Meigen) (Diptera: Tachinidae) was investigated by exposing hosts of various types to female parasitoids and observing them. One week or older females attacked hosts with little regard to time of day. They examined and attacked moving hosts preferentially and responded more to gypsy moth ( Lymantria dispar L.) (Lepidoptera: Lymantriidae) larvae than to greater wax moth ( Galleria mellonella (L.) (Lepidoptera: Pyralidae) larvae. Gypsy moth larvae which were freeze-dried were attacked even when headless, hairless, or divided in half. Evidence suggests that the parasitoid must physically contact a host before examinations and attacks occur. Integumentary chemicals may have a role, but this was not definitively shown. Females deposited larvae in host integuments filled with an agar solution to the same extent they did in living larvae.

TL;DR: The data reported here constitute the first molecular confirmation of this pest in the country, and reveal the occurrence of H. armigera in northern and central Argentina, including the main soybean- and maize-producing area.
Abstract: Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae: Heliothinae) is among the most voracious global pests of agriculture. Adults of this species were identified recently in northern Argentina by dissection of male genitalia. In this work, a rapid and simple molecular tool was designed to distinguish H. armigera from the morphologically similar indigenous bollworms Helicoverpa zea (Boddie) and Helicoverpa gelotopoeon (Dyar), regardless of the life stage. Amplification of partial COI gene with a new primer pair, and subsequent digestion with endonuclease HinfI, yielded different RFLP profiles for the three main Helicoverpa pests currently present in South America. The method was validated in Helicoverpa specimens collected across Argentina, whose identity was further corroborated by COI sequencing and phylogenetic analysis. The data reported here constitute the first molecular confirmation of this pest in the country. The survey revealed the occurrence of H. armigera in northern and central Argentina, including the main soybean- and maize-producing area.

TL;DR: The Lepidoptera of Antipodes Island are described, together with biological and ecological information on many species, and the presence of mice on the island, and their possible effect on invertebrates are discussed.
Abstract: The Lepidoptera of Antipodes Island are described, together with biological and ecological information on many species. Twenty‐two species are now recorded, of which 20 are believed to be breeding there. One of these is a world‐wide domestic species, while four are considered to be endemic to the island. Close faunal relationships are demonstrated with the moth fauna of Bounty, Chatham and the South Island of New Zealand. The total list of Lepidoptera for the subantarctic islands south of New Zealand is updated and discussed. The seasonality, dependence on disturbed areas and diurnal activity of the moth fauna are commented on. The status of the megaherb Senecio antipodus, defoliated by magpie moth larvae, is discussed. The presence of mice on the island, and their possible effect on invertebrates, is discussed and a recommendation made that they be eradicated. Coleoptera and Mollusca collected are listed in an appendix.
