“…During winter dormant periods, pests employ various strategies to optimize survival during deleterious environmental conditions, including movement to alternative hosts (Norris & Kogan, ; Kristoffersen & Anderbrant, ), burrowing into leaf litter or sediments (Rozsypal et al , ), or entering diapause (Bale & Hayward, ). Overwintering can occur in insects living in subtropical climates, despite warmer winter temperatures (Yasuda, ; Gangwar et al , ). In subtropical climates, insects may experience short diurnal freezing periods (Turnock & Fields, ).…”

Patterns of habitat use by the Asian citrus psyllid,Diaphorina citri, as influenced by abiotic and biotic growing conditions

1 The Asian citrus psyllid Diaphorina citri Kuwayama (Hemiptera: Liviidae) is an economically important pest of citrus throughout Asia and the Americas because it transmits Candidatus Liberibacter asiaticus (CLas), which is the presumed causal agent of citrus greening disease. 2 We investigated whether biotic and abiotic characteristics can be used to predict Diaphorina citri population abundance and assessed whether agricultural intensity explained the distribution of D. citri populations during winter dormant periods (December to March). 3 Over two consecutive winters, we examined the abundance of D. citri in groves throughout Florida in response to four different management regimes, defined as: conventional, intermittent, unmanaged and organic. 4 During both years, the winter abundance of D. citri in groves with intermittent management was greater than in groves with other management regimes. Latitude and row orientation both had a significant effect on psyllid density during winter. Diaphorina citri abundance was higher when more than 20% of the surrounding landscape was urbanized. 5 These findings suggest that only conventional management of groves reduced D.citri populations during winter periods. By contrast, intermittent management was associated with higher D. citri populations. These results might be of some concern in light of the economic and environmental costs of repeated insecticide applications and the dramatic decline of citrus production in the U.S.A.

“…Predators used augmentatively for biological management include different species of Coccinella (Coleoptera: Coccinellidae), Chrysoperla (Neuroptera: Chrysopidae), Staphylinidae (Coleoptera), Syrphidae (Diptera), Reduviidae (Hemiptera), and Phytoseiulus persimilis (Mesostigmata: Phytoseiidae).The other success stories in biological management include the management of Pyrilla perpusilla (Hemiptera: Lophopidae) was the utilization of egg parasitoids such as Tetrastichus pyrillae (Hymenoptera: Eulophidae) and ectoparasitoids Epipyrops melanoleuca (Lepidoptera: Epipyropidae) in subtropical india (Gangwar et al, 2008). Eriosoma lanigerum (Hemiptera: Aphididae) and Quadraspidiotus perniciosus (Hemiptera: Diaspididae) inflict damage to different species of Malus (Rosaceae) plantations and have been successfully controlled by their biological management agents.…”

Integrated pest management (IPM) programmes are based on using multiple methods to maintain nuisance insects below tolerant levels in crop fields. Recent advances in IPM in developed countries have incorporated biological pesticides, microbial products, semiochemicals, and beneficial insects, but few of such programmes have been successfully implemented in developing countries, such as India. Semiochemicals play critical roles as signals in various interspecific and intraspecific interactions between insects and plants, and among interacting insects, plants, and microbes. In India IPM programmes have included mechanical, chemical, cultural, and biological management strategies. However, among these methods, biological management has its own limitations. Indian IPM scientists mostly work on individual crops, assessing damage severity by specific nuisance arthropods and the efficacy of particular management measure. However, very few government institutions or commercial companies are engaged in developing and commercializing either biological pesticides or semiochemicals. Government institutions mostly focus on research on pheromones of the pestiferous Lepidoptera and Coleoptera. Developing IPM programmes requires a clear understanding of crop-plant development, biology and population dynamics of the nuisance organisms, and the chemical and molecular interactions between the two. It also necessarily requires local knowledge of available, prevalent management tactics. Moreover, the IPM programmes have not been widely adopted in developing countries due to lack of proper knowledge and training farmers in efficient IPM practices, the need for more of human labour, and the complexity of IPM practices, all of which impede on the effective implementation of IPM programmes. In this article, we recapture the historical development of IPM efforts in India and ask whether this concept remains suitable to the present-day challenges in crop production. In this review, more specifically, those factors identified as obstacles to the more widespread adoption of IPM and ways of overcoming such barriers are discussed.

“…Fulgoraecia melanoleuca has been reported from India, Sri Lanka, Pakistan, and Bangladesh (Kumarasinghe & Wratten 1996). It has played a major role in the management of the sugarcane Pyrilla epidemics (Gangwar et al 2008). Although it has been recorded in India in 1939 (Fletcher 1939), its biocontrol potential was recognized only during the Pyrilla epidemics in Uttar Pradesh and Bihar (Banerjee 1973).…”

Occurrence of Fulgoraecia (= Epiricania) melanoleuca (Lepidoptera: Epipyropidae) as a parasitoid of sugarcane lophopid planthopper Pyrilla perpusilla in Tamil Nadu (India) with brief notes on its life stages

Seasonal incidence of sugarcane planthopper Pyrilla perpusilla Walker (Hemiptera: Lophopidae) and its natural enemies was investigated at Cuddalore District, Tamil Nadu during 2018. In this study, Fulgoraecia melanoleuca, a parasitoid of sugarcane planthopper Pyrilla perpusilla was observed in large numbers in the field. Brief notes on its biology, life stages, and extent of parasitism on the host were studied. Per cent parasitization in nymph and adult was 47.54 and 45.09, respectively, during the month of August. High resolution images of all life stages are provided to help in identification.
