AbstractThe tomato looper, Chrysodeixis chalcites (Esper) (Lepidoptera: Noctuidae), is a major pest that feeds on some fodder crops, vegetables, and ornamental plants in diverse plant families. We studied the effect of different cultivars of tomato including: Cal.JN3, Hed Rio Grande, Rio Grande UG, SUN 6108 f1, Super crystal, and Super strain B on the life history of C. chalcites under laboratory conditions (25±1 °C, 65±5% relative humidity, and 16:8 (light:dark hours). Data were analysed using the age-stage, two-sex life table method. Tomato cultivars had significant effects on developmental time of larvae, pupae, and total preadult stages of C. chalcites. The longest (17.39 days) and the shortest (13.93 days) larval period were observed on Hed Rio Grande and SUN 6108 f1, respectively. The longest pupal period was observed on Cal.JN3 (12.16 days) and Hed Rio Grande (12.11 days) compared with other cultivars. The lowest amount of larval growth index and rate of ovipositon days was observed on Cal.JN3. The results of this study revealed that Cal.JN3 and Hed Rio Grande were the less suitable cultivars to C. chalcites compared with other cultivars studied and can be used in integrated pest management programme of this pest.

Abstract We evaluated the host suitability and related traits of Trichoplusia ni Hübner (Lepidoptera: Noctuidae) and Chrysodeixis chalcites Esper (Lepidoptera: Noctuidae), which is nonnative in North America, for the native parasitoids Campoletis sonorensis Cameron (Hymenoptera: Ichneumonidae) and Copidosoma floridanum Ashmead (Hymenoptera: Encyrtidae), and the nonnative parasitoid Cotesia vanessae Reinhard (Hymenoptera: Braconidae). For the larval parasitoid C. sonorensis and C. vanessae trials, three-day-old larvae of both hosts were used, whereas one-day-old eggs of both hosts were used for the egg–larval parasitoid C. floridanum trial. For suitability parameters on each host exposed separately to each of the three parasitoid species, we measured parasitoid emergence (parasitoid success), parasitoids that did not emerge (parasitoid cocoon mortality), the proportion of male offspring (parasitoid sex ratio), hosts that developed into moths (host success), hosts that died without developing into moths or producing a parasitoid (host mortality), parasitoids emerging from cocoon masses (brood size), and the developmental times of parasitoids and hosts. For C. sonorensis, the native host and the nonnative host were found to be similarly suitable. For C. vanessae, the native host was more suitable than the nonnative host. For C. floridanum, the native host was suitable, whereas the nonnative host was not; however, sublethal effects on both the native and nonnative hosts were observed. The differential suitability of the hosts observed in this study contributes to the understanding of this measure as a dynamic factor in the expansion of parasitoids into novel host species.

Penelitian ini dilaksanakan di desa Balung Lor, kecamatan Balung, kabupaten Jember, selama tiga bulan dimulai September sampai dengan Nopember 2013, bertujuan untuk mengetahui pengaruh teknik budidaya kubis terhadap diversitas arthropoda dan intensitas serangan P. xylostella L. Indeks keanekaragaman arthropoda dianalisis menggunakan indeks keanekaragaman Shanon-Wiener (H'), indeks domonansi  Simpson (D) dan indeks kemerataan jenis (E). Untuk membedakan  intensitas serangan P. xylostella L.   menggunakan       uji T pada taraf 5%. Kesimpulan penelitian ini sebagai berikut: diversitas arthropoda pada agroekosistem kubis yang dibudidayakan secara organik maupun konvensional menunjukkan jumlah kelas, ordo, famili dan spesies yang sama yaitu dua kelas,  tujuh ordo, empat belas famili dan enam belas spesies. Status dalam jaring makanan meliputi hama terdiri atas sembilan spesies yaitu Oxya chinensis (Orthoptera: Acrididae), P. xylostella L.

Alphabaculovirus of Chrysodeixis chalcites (ChchNPV-TF1) has been investigated as a useful bioinsecticide against C. chalcites (Esper) (Lepidoptera: Noctuidae) in banana crops. This study investigated the effects of several substances on the persistence of ChchNPV-TF1 under field conditions in the Canary Islands. Natural photoprotective substances, such as moringa, cacao, green tea, benzopurpurine, charcoal, iron dioxide, benzimidazole, kaolinite, and bentonite, were first evaluated under laboratory conditions using a Crosslinker as UV light source at 200 J/cm2. The photoprotective substances were divided into three groups: low protection (0–8%; kaolinite), intermediate protection (48–62%; green tea, moringa, bentonite and cacao) and high protection (87–100%; charcoal, iron ioxide). Benzopurpurine and benzimidazole did not provide any photoprotective effects. Two of the substances that yielded the best results, 1% cacao and 1% charcoal, were selected for the open-field experiment in a banana plantation. The persistence of ChchNPV-TF1 OBs (occlusion bodies) on leaf surfaces with sunlight exposure was analysed by comparing the initial mortality of 2nd instar C. chalcites larvae with the mortality observed at various intervals postapplication. The mortality rates decreased over time in all treatments and were always higher in the UV-protective substance-treated parcels. The 1% charcoal treatment exhibited the highest protection in both the laboratory and field experiments. No specific interference of UV-protective substances on the maximum photochemical efficiency of banana plants was observed under field conditions.

Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae) is a polyphagous moth species that mainly damages various crops and ornamental plants. This widely distributed pest is particularly a nuisance in Pakistan where it damages many crops, e.g., wheat and vegetables. To assess the risk of damage by this moth, we used the CLIMEX model to predict the distribution of A. ipsilon under current and future climatic conditions. Using the literature data, we collected information on the biology and ecology of A. ipsilon relevant for modelling the distribution of this species in Pakistan and worldwide under current and future climatic conditions. Our results revealed that under future climatic scenarios, the highly favourable habitat area of A. ipsilon (ecoclimatic index EI > 30) would decrease globally from 19% at present to 14% in the future, and the moderately favourable habitat area (0 < EI ≤ 15) would increase from 21 to 29%. We found that the northern areas of Pakistan will become highly suitable for the establishment of A. ipsilon. Under the current climatic conditions, the optimal habitats of A. ipsilon (EI > 30) comprised 10% and moderately favourable habitats (EI < 17) accounted for 25% of the total land area in Pakistan. Under future climatic scenarios, the optimal habitat area of the moth in Pakistan could decrease to 5% and the moderately favourable habitat area could cover 63% of the entire land area. The results can be applied in the protection of various crops and ornamental plants against A. ipsilon in Pakistan as well as worldwide.
