Convergent Lady Beetle (Hippodamia convergens) Detailing the physical features, habits, territorial reach and other identifying qualities of the Convergent Lady Beetle. It is one of the few natural enemies that are currently wild-collected from mass aggregations for … Under laboratory conditions, H.convergens carbon isotope ratios, d13C, changed after its food supply was shifted from a C 4-toaC 3-based diet of aphids produced on grain sorghum or cotton respectively. Explain your answer. The native Convergent Lady Beetle is beloved for its diet of pesky insects, benefiting plants and the people that eat them. A primary obstacle to biological control of B. cockerelli may be the low rate of parasitism even by psyllid specialists (Romney, 1939; Butler and Trumble, 2012a). Eggplant lace bug was included in keys to the Hemiptera of Missouri (Froeschner, 1944) and the lace bugs of North Carolina (Horn et al., 1979). The short days of autumn cause adult butterflies to enter reproductive diapause, and they undertake a southward journey of 3000 km or more. Hippodamia variegata was found in aphid-rich crops including alfalfa, clover, rye and vetch, and in weedy field borders and wood-land edges. It will also feed on pollen and nectar from flowers when prey is scarce. They discovered that Artemia salina (L.) eggs alone supported the development of larvae but not adult emergence, which was just 18%. Suppose a fire burns through the beetles’ habitat, leaving the trees, soil, and some rocks charred black for several years. Hamasaki and Matsui (2006) found that larvae and adults of a coccinellid Propylea japonica (Thunberg) developed and reproduced on Ephestia eggs in place of pea aphids; however, fecundity was lower for adults reared on the moth eggs. It explains what type of habitat they need and how you can provide habitat in your yard. A) Identify which beetle phenotype or phenotypes will most likely be favored in the habitat after the fire. Larval development, adult longevity, and fecundity were reported to be good. (1982) for maintaining adult R. cardinalis. They are mostly potential predators of aphids, scale insects, mealybugs, and mite pests, although a few are phytophagous. Ladybugs are voracious predators of many soft-bodied pest insects - try some in your garden today! The most comprehensive examination of B. cockerelli natural enemies was by Butler and Trumble (2012a) in California. All known species of the genus Stethorus are predators of spider mites, and several species have been reported as biocontrol agents of tetranychid pests. Despite several unsuccessful attempts, a few successful examples gave hope for aphid biocontrol practitioners. Stable carbon isotopes were used to examine colonization of an ephemeral crop habitat by Hippodamia convergens Guérin-Méneville. Discusses buying and releasing beneficial insects. Eggplant lace bug adults display complex social interactions, including maternal behavior. (1981) developed an oligidic diet supplemented with liver extracts for rearing Hippodamia convergens Guérin in vitro. This species can be found in habitats ranging from grasslands, forests, agricultural fields, gardens, and natural parks. This publication describes lady beetles and their habits. Dietary breadth represents a key component in the ecology, behavior, and evolutionary diversification of predators. (2009) tested two species of entomopathogenic fungi for use against the psyllid and found that both Metarhizium anisopliae (Metchnikoff) Sorokin and Isaria fumosorosea Wize were effective in controlling the psyllid as both adults and nymphs. 39, Issue. Smith (1965, 1966) successfully reared several coccinellid species, including C. maculata, on dried aphids supplemented with pollen. Results indicated that both species could develop on B. cockerelli but survival in the greenhouse conditions was limited, thus reducing the potential for its use. For example, prey specificity impinges directly on the use of predators in all types of biological control -- importation, as well as augmentation and manipulation (e.g., Hagen et al. An improved rearing method was later described by Okada and Matsuka (1973) and adapted by Matsuka et al. Aphid biocontrol could benefit if the prey is targeted early in the season, i.e., prey suppression initiation could be done when the aphid colony is young.
