Weed infestation is a major factor attributed for the poor yield of soybean. Field experiments were therefore conducted to evaluate the influence of row spacing and weed control methods on weed dynamics, seed yield and profitability of soybean. The use of 50 cm row spacing reduced the density and biomass of grass weed species including Digitaria horizontalis, Panicum maximum, Cynodon dactylon and Paspalum

Groundnut (Arachis hypogaea L.) is a major oilseed and cash crop of Asia and Africa. Fungal diseases, grey weevils and termites are consistent major pests in arid region inflicting damage to the groundnut production. It is not feasible to identify all the pests precisely and adopt several management practices simultaneously to protect the crop in curative mode. Therefore, an integrated biointensive

Field evaluation of roosting plants with food bait spray in managing melon fly, Zeugodacus cucurbitae in cucumber, Cucumis sativus Int. J. Pest Manag. (IF 1.091) Pub Date : 2020-07-13 Maruthadurai Ramasamy
Melon fly, Zeugodacus cucurbitae (Diptera: Tephritidae) (Coquillett) is the major pest of cucumber, Cucumis sativus. We investigated the attractiveness of roosting plants with food bait spray to manage melon fly in cucumber under open field conditions. Cucumber was planted over two successive Kharif seasons together with maize (Zea mays), castor bean (Ricinus communis), sorghum (Sorghum bicolor), and

An examination of ethical attitudes towards wild pig (Sus scrofa) toxicants in the United States Int. J. Pest Manag. (IF 1.091) Pub Date : 2020-07-10 Keith M. Carlisle; Erin E. Harper; Stephanie A. Shwiff
This research aims to understand ethical attitudes of the U.S. public towards the use of a toxicant to control wild pigs (Sus scrofa), a destructive invasive species whose population growth is proving difficult to control through conventional management methods. Using a nationwide self-administered survey with 2,186 completed and returned questionnaires, we found that among six different lethal control

Smallholder farmers’ adaptation strategies for the management of fall armyworm (Spodoptera frugiperda) in rural Ghana Int. J. Pest Manag. (IF 1.091) Pub Date : 2020-06-30 Peter Asare-Nuamah
This study examined smallholder farmers' adaptation strategies in managing fall armyworm (Spodoptera frugiperda) in rural Ghana. Using mixed methods, 378 smallholder farmers were randomly selected and surveyed, while 41 key informants were interviewed. The majority of smallholder farmers (83.1%) had experienced fall armyworm invasion with widespread and rapid invasion particularly in maize, which often

The three models for forecasting the peak period of Dendrolimus punctatus for the first generation egg Int. J. Pest Manag. (IF 1.091) Pub Date : 2020-06-26 Guangjing Qian; Xueyu Song; Shuping Zhang; Xiazhi Zhou; Yunding Zou; Shoudong Bi
To improve the accuracy of forecasting the peak period of Dendrolimus punctatus, fuzzy comprehensive evaluation method, contingency table analysis and BP neural network were used to predict peak period of D. punctatus for the first generation egg from 1983 to 2016 in Qianshan County. The forecasted values for the three methods were in 2017 and 2018 were consistent with the actual results. The historical

Metabolic resistance to pyrethroids (Py) and organophosphates (Op) in Callosobruchus maculatus (fab.) (Coleoptera: Chrysomelidae: Bruchinae) a major pest of stored cowpeas in West Africa Int. J. Pest Manag. (IF 1.091) Pub Date : 2020-06-22 Salifou Zongo; Ahmed Y. Coulibaly; Samuel Fogné Drabo; Olivier Gnankiné; Martin Kiendrebeogo; Ali Doumma; Mbacké Sembène; Antoine Sanon
Callosobruchus maculatus is the main pest of stored cowpeas in West Africa. To control this pest, chemicals are frequently used during post-harvest storage. In this study we assessed insecticide resistance in C. maculatus populations collected from Burkina Faso, Senegal and Niger. Enzyme analysis was also performed to detect the basic mechanisms underlying insecticide resistance. Burkina Faso western

Entomopathogenecity of nematode Panagrolaimus spp. (Rhabditida: Panagrolaimidae) against lepidopteran pest Spodoptera litura Int. J. Pest Manag. (IF 1.091) Pub Date : 2020-06-17 Vadivel Amutha; Govindaraj Vengateswari; Muthugounder Subramanian Shivakumar
Agricultural pests cause huge loss to agricultural production. Their control using biopesticides is gaining importance. Entomopathogenic nematodes (EPNs) are most promising biopesticides in agriculture. EPN like other biopesticides has a very specific action on one species or related species as against chemical insecticides. In addition, the median lethal time for EPNs is also lower. Hence there is

Evidence of fungal structures in the mandible and elytra of Hypocryphalus mangiferae collected from mango trees showing symptoms of mango sudden decline disease Int. J. Pest Manag. (IF 1.091) Pub Date : 2020-06-10 Rogério Machado Pereira; Gustavo Ferreira Martins; Ricardo Siqueira da Silva; Tarcísio Visintin da Silva Galdino; Dalton de Oliveira Ferreira; Carlos Alberto Hector Flechtmann; Marcelo Coutinho Picanço
Ceratocystis fimbriata plays a significant role in the initiation of the tree decline disease in mango (Mangifera indica L.), which can kill the plant. The C. fimbriata infection is linked with the presence of the beetle Hypocryphalus mangiferae (Curculionidae: Scolytinae). However, it is unknown how H. mangiferae aids in the transport of the fungus between mango trees. The present study aimed to investigate

Efficient biocontrol of Spodoptera littoralis by Aspergillus nidulans, an endophyte of Lantana camara Int. J. Pest Manag. (IF 1.091) Pub Date : 2020-06-08 Ashraf S.A. El-Sayed; Ahmed H. Moustafa; Aly A. El-Sheikh; Amgad M. Rady; Nahla A.M. Fathy; Hussein A. Hussein; Gamal Enan; Marwa A. Yassin
Spodoptera littoralis has been recognized as a very destructive polyphagous insect, thus, searching for novel bioagents is the current challenge. Endophytic fungi have been recognized as repertoire for bioactive compounds. Thus, the objective of this work was to isolate endophytic fungi inhabiting Lantana camara and evaluating their insecticidal activity against S. littoralis. Aspergillus nidulans
