“…Should aguacatae scale become established in Florida, it may arrive with E. lounsburyi parasitoids from Mexican populations or acquire them secondarily from populations already present in Florida. However, due to natural population-level genetic variation that may influence host seeking behavior and likelihood of survival through development, the fidelity of the association between host and parasitoid may vary depending on the provenance of the host and parasitoid (Hopper et al 1993;Allendorf & Lundquist 2003;Uesugi et al 2016). Recent examples relevant to Florida are the lepidopteran citrus pest Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) and the parasitoid Ageniaspis citricola Logvinovskaya (Hymenoptera: Encyrtidae) (Hoy & Nguyen 1997), and the noxious adventive plant Brazilian peppertree, Schinus terebinthifolia Raddi (Anacardiaceae) and the herbivore Pseudophilothrips ichini (Hood) (Thysanoptera: Phlaeothripidae) (Cuda 2016).…”

Armored scale insects include invasive economic pests that have been widely studied in human-altered habitats but have received less attention in natural habitats. Although armored scale insects are nearly ubiquitous associates of woody plants, they generally go uncollected in general surveys because they are not susceptible to mass collecting techniques, such as fogging, beating, or trapping. San Lorenzo National Park in Panama was the subject of a recent high-profile effort to quantify the arthropod diversity in a tropical forest (Basset et al. 2012). Here, we contribute to understanding the biodiversity of this classic site by reporting the armored scale insect species we found there in August 2010. We found that, unlike other rainforest canopy taxa, the armored scale insect fauna is dominated by highly polyphagous cosmopolitan pests. However, we also found new species, and we describe two of them here: Furcaspis douglorum Okusu & Normark n. sp. and Hemiberlesia andradae Okusu & Normark n. sp. We provide amendments to the relevant keys, including a new key to New World species of Hemiberlesia Cockerell that lack perivulvar pores. In this context, we treat Abgrallaspis Balachowsky as asubjective synonym of Hemiberlesia, and we transfer its species to Hemiberlesia, except for the following assignments to other genera Affirmaspis flavida (De Lotto), n. comb., Aspidiotus furcillae Brain, rev. comb., Clavaspis perseae (Davidson), n. comb., Diaspidiotus fraxini (McKenzie), n. comb., and Davidsonaspis aguacatae (Evans, Watson, and Miller), n. comb. Davidsonaspis Normark, n. gen. We regard Abgrallaspis azadirachti Ojha and A narainus Dutta & Singh as synonyms of Aonidiella orientalis (Newstead), new synonymy.

“…Assim, é possível que, para o controle de uma determinada espécie de hospedeiro, sejam necessárias várias espécies de parasitóides ou de indivíduos de uma mesma espécie, porém, oriundos de populações adaptadas em diferentes condições climáticas (Messenger & Van Den Bosch 1971). Indivíduos provenientes de populações de parasitóides originadas de regiões climaticamente diferentes podem apresentar desenvolvimento, fecundidade e mortalidade diferenciados, dependendo da temperatura à qual são expostos (Botto et al 1988;Bleicher & Parra 1989;Bleicher & Parra 1990a b;Hopper et al 1993;Mols & Boers 2001;Royer et al 2001;Liu et al 2002).…”

ABSTRACT. Response to temperature of Aphidius colemani Viereck (Hymenoptera, Braconidae, Aphidiinae) from three climatic regions of Minas Gerais state, Brazil. The parasitoid Aphidius colemani Viereck, 1912 presents higher mortality at constant temperatures above 25°C, and probably it is the cause of the failure on the biological control of Aphis gossypii Glover, 1877 when this parasitoid is used at higher temperatures in greenhouses. The aim of this work was to evaluate the influence of different temperatures on individuals of A. colemani from different climatic regions of Minas Gerais state, Brazil. Individuals of A. colemani were collected in the localities of Juramento, Lavras and São Gotardo, and reared in laboratory (22±2°C, 70±10% RH and 12h photophase) for three generations in the host A. gossypii, on cucumber plants. One mated female of A. colemani, 24-48 h old, was released for one hour, in a Petri dish (15cm) with 20 nymphs of 2 nd instar of A. gossypii on a leaf disk of cucumber (4 cm of diameter) laid on a layer of agar-water (1%). The parasitized aphids were kept at 16, 19, 22, 25 and 28±1°C, 70±10% RH and 12h photophase. The emergence rates of individuals from Juramento (65.9 and 35.4%) and São Gotardo (71.4 and 47.6%) were lower compared to those from Lavras (87.1 and 80.9%) at 16 and 28°C. The more suitable temperature for the development of A. colemani from Lavras was higher than those for individuals from Juramento and São Gotardo. The individuals from Lavras showed highest emergence at 28°C, and this demonstrated the existence of individuals of A. colemani with tolerance to higher temperatures. These results open news perspectives on the use of different strains of A. colemani on biological control of A. gossypii in protected cultivation.

“…Host race has been characterized by genetic, behavioral, or combined genetic and behavioral diVerentiation (Craig et al, 1993(Craig et al, , 2000Diehl and Bush, 1984;Drès and Mallet, 2002;Hopper et al, 1993;Narang et al, 1993). Drès and Mallet (2002) point out that the deWnition of "host race" is elusive, and that conferring the status of "host race" is a subjective categorization of "one of a number of intermediates in the continuum between polymorphisms and full species.…”

Hansen, Richard W.; and Markin, George P., "A retrospective analysis of known and potential risks associated with exotic toadflax-feeding insects" (2005 AbstractTo date, eight exotic toadXax-feeding insect species have been accidentally or intentionally introduced to North America. Reports on their establishment and impact have been recorded for more than 60 years. Environmental risks linked to biological control of toadXax were identiWed in terms of host resources and undesirable impacts on the target species through the critical review of this record. Data gaps revealed during this retrospective analysis are addressed through suggestions for future research and associated experimental methodologies. Known and potential impacts of toadXax-feeding insects on both invasive toadXax and non-target species are examined. Recent programmatic demands for demonstrated agent eYcacy and stringent host selectivity during the prerelease screening process clearly illustrate that classical biological control of invasive toadXax in North America is progressing beyond the so-called lottery approach. 
