AbstractThe term ‘dead-end trap cropping’ has recently been proposed to identify a plant that is highly attractive for oviposition by an insect pest, but on which offspring of the pest cannot survive. The potential of the wild crucifer Barbarea vulgaris R. Br. to allure and serve as a dead-end trap crop for the diamondback moth Plutella xylostella (L.), an important pest of cruciferous crops worldwide, was examined in laboratory experiments. When P. xylostella adults were provided with a dual-choice of plants of B. vulgaris, and Chinese cabbage Brassica campestris (L.), in one arena, adult moths laid 2.5–6.8 times more eggs on the former than on the latter. When P. xylostella adults were provided with a dual-choice of plants of B. vulgaris and common cabbage Brassica oleracea L., adult moths laid virtually all their eggs on the former and ignored the latter. Nearly all P. xylostella eggs laid on the three species of plants hatched successfully, but nearly all individuals on plants of B. vulgaris died as neonates or early instar larvae, while 87–100% of the larvae on Chinese cabbage and common cabbage survived to pupation. Dual choice tests with a Y-tube olfactometer showed that volatiles from B. vulgaris were much more attractive to P. xylostella adults than those from common cabbage. The results demonstrate that B. vulgaris has a great potential as a dead-end trap crop for improving management of P. xylostella. Factors that may influence the feasibility of using B. vulgaris as a trap crop in the field are discussed, and ways to utilize this plant are proposed.

The chinch bug, Blissus leucopterus leucopterus (Say) (Heteroptera: Blissidae), is the most important insect pest of pearl millet (Pennisetum glaucum L. R. Br.) production in the southeastern and central United States. Chinch bug feeding causes stunting and leaf sheath necrosis of the young seedlings and loss of crop stand in severe infestations. Sixteen germplasm entries (including hybrids and inbreds) of pearl millet were screened for chinch bug resistance on 2 planting dates. ‘Dove’ proso millet (Panicum miliaceum L.) was interplanted in 2-row strips among experimental plots to attract adult chinch bugs and establish initial chinch bug infestations. Use of a proso millet trap crop strip was effective in establishing chinch bug infestations for screening of pearl millet for chinch bug resistance in the field. Weekly samplings were begun when plants were at the 5-leaf stage. Significant differences in adult and nymph numbers, stunting and necrosis ratings, percent tiller loss, crop stand loss, and chlorophyll content were recorded for the 16 pearl millet germplasm entries. Combining all injury evaluation parameters (i.e., stunting and necrosis ratings, percent tiller loss, and crop stand loss), we identified that ‘TifGrain 102’ had a moderate level of chinch bug resistances e data demonstrated that, millet would aeh resistance. Entries 637 (i.e., 59668A × NM-5B), 639 (59668M × 9Rm/4Rm), 648 (i.e., 02GH973 × Tift 454), and 653 (i.e., NM-5A1 × NM-7R1R5) were the most resistant; whereas, entries 640 (i.e., Tift 99B), 641 (i.e., Tift 454), and 644 (i.e., 02F 289-1) were the most susceptible to chinch bug feeding. The study showed the combination of nondestructive visual ratings (i.e., stunting and necrosis ratings, tiller loss, and stand loss) and chlorophyll content could be used for evaluating chinch bug resistance in pearl millet.

Abstract The brown marmorated stink bug, Halyomorpha halys (Stål 1855) (Hemiptera: Pentatomidae) is an invasive and economically important agricultural and ornamental insect pest nowadays established in many countries. There are numerous methods used for its control. Due to the increased risk of chemical contamination upon the application of synthetic insecticides to control harmful insects, essential oils are gaining increasing attention. In this research, the insecticidal effectiveness of Satureja spicigera (C. Koch) Boiss (Laminaceae) essential oil at 10, 15 and 20 μL/mL doses, and 24, 48, 72 and 96 h against five nymph instars and adults of H. halys was investigated. In addition, the chemical analysis of S. spicigera essential oil was done by GC-MS. The major components of the S. spicigera oil were carvacrol (32.14%), thymol (20.01%), ɣ-terpinene (17.05%), p-cymene (9.08%) and carvacrol methyl ether (5.70%). At the 96th h of the study, the essential oil caused a mortality rate of between 20.1 and 87.5%. The positive control (Nimbecidine®) had the highest mortality rates for nymphs (100%) and adults (90.3%). According to the LD50 and LD90 values, while the most toxic LD50 values were recorded as 0.63 and 4.66 μL/mL for the N1 instar and adults, the lowest LD90 values were 19.12 and 26.32 μL/mL for the N5 instar and adults, respectively. In conclusion, results showed that S. spicigera oil had a highly toxic effect against five nymph instars and adults of H. halys.

Abstract BackgroundBrown marmorated stink bug (BMSB), Halyomorpha halys (Hemiptera: Pentatomidae) is native to East Asia but has invaded many countries in the world. It is a polyphagous insect pest and causing significant economic losses to agriculture worldwide. Knowledge on the genetic diversity among BMSB populations is scarce but is essential to understand the patterns of colonization and invasion history of local populations. Efforts have been made to assess the genetic diversity of BMSB using partial mitochondrial DNA sequences but genetic divergence on mitochondria is not high enough to precisely identify and distinguish various BMSB populations. Therefore, in this study, we applied a ddRAD (double digest restriction-site associated DNA) sequencing approach to ascertain the genetic diversity of BMSB populations collected from 12 countries (2 native and 10 invaded) across four continents with the ultimate aim to trace the origin of BMSBs intercepted during border inspections and post-border surveillance.ResultA total of 1775 high confidence single nucleotide polymorphisms (SNPs) were identified from ddRAD sequencing data collected from 389 BMSB individuals. Principal component analysis (PCA) of the identified SNPs indicated the existence of two main distinct genetic clusters representing individuals sampled from regions where BMSB is native to, China and Japan, respectively, and one broad cluster comprised individuals sampled from countries which have been invaded by BMSB. The population genetic structure analysis further discriminated the genetic diversity among the BMSB populations at a higher resolution and distinguished them into five potential genetic clusters. ConclusionThe study revealed hidden genetic diversity among the studied BMSB populations across the continents. The BMSB populations from Japan were genetically distant from the other studied populations. Similarly, the BMSB populations from China were also separated from the Japanese and other populations. Further genetic structure analysis revealed the presence of at least three genetic clusters of BMSB in the invaded countries, possibly originating from multiple invasions. Furthermore, this study has produced novel set of SNP markers to enhance knowledge of genetic diversity among BMSB populations and demonstrate a great potential to trace the origin of BMSB individuals for future invasion events.

The New Zealand endemic wheat bug, Nysius huttoni (Hemiptera: Lygaeidae), is a pest of brassica seedlings. However, it has a wide host range comprising almost all cultivated brassicas, cereals and many other cultivated crops, as well as weeds. The brassica alyssum (Lobularia maritima) is a potential trap crop of N. huttoni, having the potential to keep the bugs away from seedlings. Laboratory no-choice and choice tests evaluated the relative preference of N. huttoni for two major growth stages of alyssum – vegetative and flowering. In both bioassays, N. huttoni adults settled significantly more promptly on the flowering than on the vegetative stage. The same preference was evident for adult numbers settling. Survival was higher on the flowering (38%) than on the vegetative stage (28%), although this was not significant. The implications of these findings are important in the design of trap cropping protocols for N. huttoni management. Flowering alyssum in brassica fields can also potentially improve pest biological control and provide other ecosystem services that can contribute to mitigating diminished ecosystem functions in agriculture.
