“…The abiotic factors, mainly temperature, precipitation and relative humidity, have a great influence on the biological cycle of the insects (Wellington ; Messenger , ; Cammell & Knight ; Peacock et al . ; Battisti & Larsson ; Sable & Rana ). For most Melolonthidae, longer biological cycles, which can last from two to five years, are recorded in species inhabiting temperate regions where temperature seems to be the factor that determine the life cycle duration (Ritcher ; Forschler & Gardner ).…”

“…Climate is one of the main factors responsible for regulating insect populations, directly influencing the biology and behaviour of species (Wellington ; Messenger , ; Cammell & Knight ; Peacock et al . ; Battisti & Larsson ; Sable & Rana ). In temperate regions, low temperatures, which occur in winter (often below zero), represent one of the main obstacles within the biological cycle of insects, requiring the use of survival strategies such as diapause (Addo‐Bediako et al .…”

Phyllophaga capillata (Blanchard) is the most important soil pest in soybean crops in Central Brazil (Federal District and Goiás state). The objective of this work was to study the bio-ecology of P. capillata in the field in the Cerrado of Central Brazil, relating its biology and behaviour to the climatic characteristics of this biome. The study was conducted over three years in a soybean [Glycine max (L.) Merr.] production area (≈6000 ha) in the Federal District. Field samplings were taken to observe the biological stages of P. capillata, preferred oviposition sites and the adult swarming period. Phyllophaga capillata presented an univoltine cycle that lasted about 10 months of egg to inactive adults, and 12 months until the appearance of active adults. Eggs were found in the field in October and November. The larval stage occurred between November and June. Pre-pupae were observed in June and the pupae between July and August. Inactive adults were observed in August and September, and the swarming period was between September and December. Females preferred to oviposit in sites with taller plants. This species synchronises its active phases (larvae and active adults) with soybean cultivation and the rainy season (October/ March) in the Brazilian Cerrado. Alternatives for pest management based on their bio-ecological characteristics are presented.

Phyllophaga nitididorsis (Coleoptera: Melolonthidae), the first biennial melolonthid recorded in the Brazilian Cerrado

Phyllophaga nitididorsis Frey, a species native to Brazil, has recently been recorded as a soil pest in soybean Glycine max (L.) Merr. fields in the north-west region of Minas Gerais (MG), Brazil. Our study aimed to evaluate the phenology of P. nitididorsis in the Cerrado of Central Brazil. The study was conducted in a field (≈300 ha) in Buritis/MG where soybean is sown in October (spring) annually. Monthly (December 2012-November 2014) samples were collected by opening trenches (50 cm × 50 cm and 30 cm in depth), recording the developmental phases of all P. nitididorsis found. Specimens collected from the field were maintained in the laboratory at 25 (±2°C), and their development was recorded at weekly intervals. Light traps were installed in the states of Minas Gerais, Goiás (GO), and the Federal District (DF) to verify species distribution. P. nitididorsis exhibited a biennial life cycle that lasted approximately 22 months, from egg to inactive adult, and 24 months from egg until the emergence of active adults. Eggs were found in the soil in November. The larval stage lasted about 20 months (≈607 days). Second-instar and third-instar larvae constructed chambers in the soil to overwinter during the dry season (March to September) during the first and second years of development, respectively. Pre-pupae were observed between July and August and pupae between July and September. Inactive adults occurred in August and September, and the swarming period was between October and November. Adult P. nitididorsis were caught in all of the States where light traps were operated. The active phases of the insect (larvae and adults) were synchronised with soybean cultivation and the rainy season (October and March) in the Cerrado. To the best of our knowledge, our study is the first to report P. nitididorsis in the states of Goiás and the Federal District. Further, this species is the first biennial melolonthid observed in the Brazilian Cerrado.

Population dynamics of lentil aphid Aphis craccivora (Hemiptera: Aphididae) was assessed in relation with climatic parameters at the research field of National Maize Research Program (NMRP), Rampur, Chitwan during winter season of two consecutive years 2016 to 2018. The experiment was organized in randomized complete block design consisting 20 lentil varieties with three replications. The crop was sown during last week of November in both the years. The daily meteorological parameters like maximum temperature (Tmax), minimum temperature (Tmin), relative humidity (RH) and rainfall (Rf) were recorded at the meteorological station located in NMRP, Rampur, Chitwan and then converted into weekly basis as the standard meteorological week (SMW) with correspondence to weekly population of aphid. The incidence of aphid was started from 2nd SMW of January (2 aphid/plant/10 cm apical twigs) during both experimentation years. Initially the population was low and gradually increased and reached to its peak (49 aphid/plant/10cm apical twigs) on 9th SMW i.e. first week of March with correspondence to weather parameters viz. maximum and minimum temperature (°C), relative humidity (%) and rainfall (mm) were 30.80, 15.34, 67.72 and 0, respectively over the years. The aphid population had significant positive correlation with Tmax (r= 0.94) while the Tmin showed highly significant correlation (r=0.99). The relative humidity (RH) had non significant negative correlation (r= -0.90) and rainfall (Rf) showed non significant negative impact (r= - 0.15) with aphid population. The regression model developed could explain 99% variation in aphid population in different cultivars of lentil. SAARC J. Agri., 17(2): 155-164 (2019)
