A new rearing method using carrots as food for the brown-marmorated stink bug, Halyomorpha halys (Stål) (Heteroptera: Pentatomidae)

Abstract

In order to improve the rearing efficiency of Halyomorpha halys, I developed a new rearing method using carrots with a peanut-soybean diet. Nymphs were reared under one of three food conditions, as follows: FC-A, raw peanuts and dry soybean seeds (a conventional rearing method); FC-B, carrot flesh only; and FC-C, carrot flesh, raw peanuts and dry soybean seeds. The adult emergence ratio of nymphs on FC-C was significantly higher than on FC-A, and was as high as on FC-B. The developmental period of nymphs fed FC-C was not significantly different from that of those fed FC-A, and was significantly shorter than those fed FC-B. The body size of adults fed FC-C was significantly greater than that fed FC-A, but that fed FC-B was significantly inferior to that of FC-A. The nutritional status of adults fed FC-C was not significantly different from that of those fed FC-A, and was significantly greater than those fed FC-B. The survival period and the number of eggs deposited by females fed FC-C were not significantly different from those fed FC-A, and were significantly greater than those fed FC-B. These results suggest that adding carrots to a peanutsoybean diet significantly improves the rearing of successive generations of H. halys.

Development and comparison of trunk traps to monitor movement of Halyomorpha halys nymphs on host trees

“…Lee et al (2014) demonstrated that the dispersal capacity of H. halys nymphs by walking is considerable. ), concurring with Funayama (2006), and further suggesting the likelihood that nymphs move among hosts during the season. When attractive olfactory stimuli were deployed in a mowed grassy field near a woodlot, Lee et al (2014) reported that responding nymphs walked over a distance of 20 m within 4-5 h. These findings suggest that H. halys nymphs can move readily among host plants growing near one another.…”

“…Moreover, H. halys nymphs exhibited higher survivorship and faster development when reared on mixed diets of wild and cultivated tree hosts than on single diets of most of the same hosts (AL Acebes-Doria, unpubl. ), concurring with Funayama (2006), and further suggesting the likelihood that nymphs move among hosts during the season.…”

Rearing Protocol and Density Trials of the Brown Marmorated Stink Bug (Hemiptera: Pentatomidae) in the Laboratory

“…Food was administered by placing 2 prewashed organic baby carrots, 3 prewashed organic green beans, and approximately 20 organic sunflower seeds into the dorm. The food provided to H. halys in this protocol is consistent with the types of food used in other studies (Funayama 2006;Li et al 2007;Medal et al 2012;Haye et al 2014). Funayama (2006) used carrots, soybeans, and peanuts as food for this insect.…”

Diversity of mung bean insect pests and their natural enemies in farmers’ fields in East Java, Indonesia

“…Pod sucking bugs are an important pest and are polyphagous insects (Figure 3). These pests attack several species in the family Leguminosae, such as soybeans, mung beans, peanuts, pigeon pea, cowpea, common beans, alfalfa, Crotalaria sp., and Sesbania rostrata (Funayama 2006;Nakamura and Numata 2006). Pod sucking bugs are widespread in tropical and sub-tropical areas, including Indonesia, South Japan, America, Australia, and Europe (Musser et al 2010;Temple et al 2011;Wada et al 2006).…”
