EENY157 Florida Predatory Stink Bug (unofficial common name), Euthyrhynchus floridanus (Linnaeus) (Insecta: Hemiptera: Pentatomidae)1 Frank W. Mead and David B. Richman2 Introduction Distribution The predatory stink bug, Euthyrhynchus floridanus (Lin- Euthyrhynchus floridanus is primarily a Neotropical species naeus) (Figure 1), is considered a beneficial insect because that ranges within the southeastern quarter of the United most of its prey consists of plant-damaging bugs, beetles, States. and caterpillars. It seldom plays a major role in the natural control of insects in Florida, but its prey includes a number Description of economically important species. Adults The length of males is approximately 12 mm, with a head width of 2.3 mm and a humeral width of 6.4 mm. The length of females is 12 to 17 mm, with a head width of 2.4 mm and a humeral width of 7.2 mm. Euthyrhynchus floridanus (Figure 2) normally can be distinguished from all other stink bugs in the southeastern United States by a red- dish spot at each corner of the scutellum outlined against a blue-black to purplish-brown ground color. Variations occur that might cause confusion with somewhat similar stink bugs in several genera, such as Stiretrus, Oplomus, and Perillus, but these other bugs have obtuse humeri, or at least lack the distinct humeral spine that is present in adults of Euthyrhynchus. In addition, species of these genera Figure 1.

Picromerus Bidens (Heteroptera: Pentatomidae) As Predator of the Checkerspot Euphydryas Aurinia (Lepidoptera: Nymphalidae)
© Entomologica Fennica. 16 December 2005 Picromerus bidens (Heteroptera: Pentatomidae) as predator of the Checkerspot Euphydryas aurinia (Lepidoptera: Nymphalidae) Martin Konvicka, Vladimir Hula & Zdenek Fric Konvicka, M., Hula, V.& Fric, Z. 2005: Picromerus bidens (Heteroptera: Penta- tomidae) as predator of the Checkerspot Euphydryas aurinia (Lepidoptera: Nymphalidae). — Entomol. Fennica 16: 233–236. The predatory bug Picromerus bidens is reported as a regular predator of the Marsh Fritillary Euphydryas aurinia from the region of western Bohemia, Czech Republic. Adult bugs attack pre-diapause larvae, either exposed or hidden in pro- tective silken webs, and exhibit efficient behaviour, including returning to previ- ously attacked webs. We observed predation in six out of 28 and eleven out of 21 local populations in 2003 and 2004, respectively. In addition, we observed two attacks by nymphs on handicapped adult butterflies. Predation of Melitaeinae by Heteroptera seems to be a widespread phenomenon, and P. bidens can act as a substantial mortality factor in small colonies of E. aurinia. M.

Spined Soldier Bug
Beneficial Species Profile Photo credit: Russ Ottens, University of Georgia, Bugwood.org; Gerald J. Lenhard, Louisiana State University, Bugwood.org Common Name: Spined soldier bug Scientific Name: Podisus maculiventris Order and Family: Hemiptera; Pentatomidae Size and Appearance: Length (mm) Appearance Egg 1 mm Around the operculum (lid/covering) on the egg there are long projections; eggs laid in numbers of 17 -70 in oval masses; cream to black in color. Larva/Nymph 1.3 – 10 mm 1st and 2nd instars: black head and thorax; reddish abdomen; black dorsal and lateral plates. Younger instars are gregarious; cannibalistic. 3rd instar: black head and thorax; reddish abdomen with black, orange, and white bar-shaped and lateral markings 4th instar: similar to 3rd instar; wing pads noticeable 5th instar: prominent wing pads; mottled brown head and thorax; white or tan and black markings on abdomen. Adult 11 mm Spine on each shoulder; mottled brown body color; females larger than males; 2 blackish dots at the 3rd apical (tip) of each hind femur; 1-3 generations a year. Pupa (if applicable) Type of feeder (Chewing, sucking, etc.): Nymph and adult: Piercing-sucking Host/s: Spined soldier bugs are predators and feed on many species of insects including the larval stage of beetles and moths. These insects are found on many different crops including alfalfa, soybeans, and fruit. Some important pest insect larvae prey include Mexican bean beetle larvae, European corn borer, imported cabbageworm, fall armyworm, corn earworm, and Colorado potato beetle larvae. If there is not enough prey, the spined soldier bug may feed on plant juices, but this does not damage the plant. -
Predation by Podisus Maculiventris on Different Life Stages of Nezara Viridula

(Heteroptera: Pentatomidae) was measured in the laboratory. Both nymphal and adult predators displayed high predation rates on eggs, nymphs and adults of the southern green stinkbug. However, developmental times of fourth instar P. maculiven- tris on eggs or nymphal instars of N. viridula were longer than on fifth instars of the cotton leafworm, Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae), suggesting that N. viridula is suboptimal prey for the spined soldier bug. Preference experiments in which fourth instar P. maculiventris were given a choice between fourth instars of N. viridula and fifth instars of S. littoralis indicated that the stinkbugs were less vulnerable to predation than the caterpillars, mainly because of their greater agility. The potential role of P. macu- liventris in augmentation or conservation biological control of the southern green stinkbug in greenhouse and field crops is discussed. Key Words: Nezara viridula, Podisus maculiventris, Asopinae, predator, biological control RESUMEN La capacidad de depredación de cuartos instares y macho y hembra adultos de Podisus ma- culiventris (Say) (Heteroptera: Pentatomidae) sobre los diferentes estados del chinche verde hediondo sureño Nezara viridula (L.)

List of Biological Control Agents Widely Used in the Eppo Region
EPPO Standards SAFE USE OF BIOLOGICAL CONTROL LIST OF BIOLOGICAL CONTROL AGENTS WIDELY USED IN THE EPPO REGION PM 6/3 English 2021 VERSION oepp eppo European and Mediterranean Plant Protection Organization 21 Boulevard Richard Lenoir, 75011 Paris, France APPROVAL EPPO Standards are approved by EPPO Council. The date of approval appears in each individual standard. In the terms of Article II of the IPPC, EPPO Standards are Regional Standards for the members of EPPO. REVIEW EPPO Standards are subject to periodic review and amendment. The next review date for this set of EPPO Standards is decided by the EPPO Working Party on Phytosanitary Regulations. AMENDMENT RECORD Amendments will be issued as necessary, numbered and dated. The dates of amendment appear in each individual standard (as appropriate). DISTRIBUTION EPPO Standards are distributed by the EPPO Secretariat to all EPPO member governments. Copies are available to any interested person under particular conditions upon request to the EPPO Secretariat. SCOPE The EPPO Standards on the safe use of biological control are intended to be used by NPPOs or equivalent authorities, in their capacity as bodies responsible for overseeing and, if appropriate, regulating the introduction and use of biological control agents. OUTLINE OF REQUIREMENTS NPPOs of the EPPO region generally promote the use of biological control in plant protection because, like other aspects of integrated pest management, it reduces risks to human health and the environment. Use of biological control agents may, nevertheless, present some risks, in particular for the environment if exotic agents are introduced from other continents, and for the user if agents are formulated as plant protection products. -

Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4. -
