Five years of biological control of stored-product moths in Germany.

Abstract

The application of macroorganisms for the biological control of stored product pests in Germany is reviewed. In bakeries and mills, the Mediterranean flour moth Ephestia kuehniella is the major pest moth. The egg parasitoid Trichogramma evanescens and the larval parasitoid Habrobracon hebetor [Bracon hebetor] are released 12 months. In the food processing industry, the wholesale trade and the retail trade, the Indian meal moth Plodia interpunctella is the major pest moth. Due to the diapause of this species, the same parasitoids are released for eight months. Empty rooms were treated to control residual populations. Additional information on control actions in herb stores, seed storage and private households is given. The cost of biological control is estimated.

Modelling of the Calendering Process of NMC‐622 Cathodes in Battery Production Analyzing Machine/Material–Process–Structure Correlations

“…Electrode Materials and Composition: In this article, two different NMC-622 cathodes were used. Though they are based on the same amount and kind of components, they were made in different campaigns within the Competence Cluster for battery cell production (ProZell) [34] and differ in the type of coating application (single or double sided). Detailed specifications of the coating materials and the measured cathode data are denoted in Table 1.…”

Estimating effect of augmentative biological control on grain yields from individual pearl millet heads

“…There are several studies describing the use of commercially available H. hebetor populations in biological control, especially of pyralid pests in stored products (Brower et al. ; Prozell and Schöller ). Also detailed life table studies have been developed for this important parasitoid (Eliopoulos and Stathas ).…”

“…Habrobracon hebetor Say (Hymenoptera: Braconidae) is a well-known, gregarious ectoparasitoid of larvae from a wide range of economically important moth families, including Pyralidae (Eliopoulos and Stathas 2008;Ghimire and Phillips 2010a,b), Gelechiidae (Jackson and Butler 1984;Ghimire and Phillips 2010a,b), Tineidae (Ghimire and Phillips 2010a,b), Geometrids (Ghimire and Phillips 2010a,b), and Noctuidae (Ghimire and Phillips 2010a,b;Rabie et al 2010), including the millet head miner (Youm and Gilstrap 1993). There are several studies describing the use of commercially available H. hebetor populations in biological control, especially of pyralid pests in stored products (Brower et al 1996;Prozell and Sch€ oller 2002). Also detailed life table studies have been developed for this important parasitoid (Eliopoulos and Stathas 2008).…”

The internal bacterial diversity of stored product pests

“…Many available chemical insecticides are not advised for controlling stored product pests since the residues of the chemicals cause health problems when eaten by human beings or livestock (De Groot 2004;Matthias 2009). This has led to an increased interest in alternative control options, including biological control by mass-reared natural enemies such as parasitoids and predators of insect pests and microbial control agents (also called microbial control), such as bacteria, fungi, viruses, nematodes and protozoa (Khetan 2001;Prozell and Schöller 2002;Matthias 2009). …”
